Monthly Newsreel

 In an area of New Brunswick (Canada) the Canadian Department of Transportation had plans to construct a by-pass of Route 8 around the city of Fredericton, capital of the region.

     As part of the investigations which are made for the planning of any major road, not just in Canada, an archaeological team was sent to see if there was anything of interest. What they found was actually so important that there was an immediate cessation of ground works and the by-pass would have to be permanently re-routed.

     The find centred on a campsite, dated at 10,000 BCE, which would have been based on the shores of a long lost lake. So far over 600 artefacts have been unearthed, ranging from stone tools to arrow heads and a fire pit.

     One of the First Nation tribes of this area of New Brunswick was the Maliseet and several members of the archaeological team were members of that tribe, including Shawna Goodall, who is quoted as saying "These are my ancestors. And just to be able to be the first one to hold things in 13,000 years - I get goose bumps every timer, (from) every single artefact. That never ores away, that feeling".

     The other exciting part of the find is that it provides a missing link. Team Leader, Brent Suttie, is quoted as saying "We have a few sites down in the Pennfield area and then we have very famous sites in Debert, Nova Scotia that dates to 11,600 years old. We don't have anything between those two sites. This site just happens to fall within that".

New insight into the construction of Stonehenge
A recent discovery of a Y-shaped wooden sledge at a megalithic site in Japan has lead a team of students from the Institute of Archaeology at London University's University College (UCL), to re-think how the Stonehenge stones were transported to the site.

     Previous ideas had centred on the impractical use of tree trunks as rollers. Experiments using these failed badly as, unless the trunks were exactly the same diameter as each other and perfectly round, the immense weight of the stones rolling over them would either crush them or push them into the ground.

     This new technique uses static 'rollers' with a smooth, low friction wooden sled being pulled over them. The experiment involved a slab of stone weighing a mere 1 ton and a team of 10 managed to pull it easily, at a steady speed of 1.6 km/hour. This lead to the belief that the 2 ton bluestones from the Preseli Hills in West Wales could have been transported in this way.

     It was not possible to confirm if the same technique could have been used for the much larger (32 ton) sarsen stones, albeit the journey would have been much shorter. Even the organisers were surprised with the ease with which the experiment worked.

     Event organiser, Barney Harris, from the Institute of Archaeology, is quoted as saying "All we can really tell from experiments like this is the minimum number of people involved. My preliminary calculations led me to believe it would take slightly more people. In the event, what I thought would take 15 people, at a minimum, actually needed only 10 people".

     More experimentation, over a variety of surfaces (this experiment was conducted over the smooth manicured grass of Gordon Square, adjacent to UCL) before a more accurate, revised estimate of the construction period for Stonehenge can be made

Evidence uncovered of a thriving community in the Gobi desert
he Gobi desert is a vast area of 1,295,000 square kilometres, spread across northern China and Mongolia. It is an inhospitable, barren area, home only to hardy nomadic tribes who can withstand the harsh extremes of -43° C to +38° C. However, 40,000 years ago it painted a totally different picture, home to a wide variety of flora and fauna, interspersed with large lakes, which have long ago dried up under desertification. This period coincide with the Pleistocene and early Holocene occupation of the region.

     A team of archaeologists from the Institute of Archaeology, University of Wroclaw (Poland), has been conduction research across the southern end of the Gobi with amazing results. Not only have they found large, stone covered Iron Age tombs but also a variety of stone tools and a group of several items made of jasper, on what would have been a lookout point on one of the mountains.
     Professor Szykulski, leader of the project, is quoted as saying "The accumulation of certainly valuable material in one place proves that it had great importance for the inhabitants of the region. Perhaps the discovery is related to a rite".

     The aim of the project is to chart pre-history for this semi-arid area, between the Altai Mountains and the Gobi desert. Restricting the area to this region reduces the area to be covered but even so it stretches to a vast 50,000 square kilometres.

Researchers from the University of Oxford have revealed that the genetic ancestries of many of sub-Saharan Africa's populations are the result of historical DNA mixing events within the last 4000 years.

     Lead author George Busby, Statistical Geneticist at the Wellcome Trust Centre for Human Genetics, says: "As Africa has few written records of its history, it is somewhat unknown what important movements of people generated the populations in the continent today. Looking at and comparing the differences in the genomes of people alive today can help us better understand and reconstruct the historical interactions that brought their ancestors together."

     The team used DNA analysis to characterise the structure of genetic diversity and gene flow - the transfer of genes between different populations - in a collection of 48 sub-Saharan African groups. They discovered that most sub-Saharan populations share ancestry with groups from outside their current geographic region as a result of gene flow within the last 4000 years.

     Dr Busby explains: "Our research provides further genetic evidence that the spread of Bantu languages and agricultural technology from Central West Africa, known as the Bantu expansion, was likely to be accompanied by people who moved from Cameroon to the south and east within the last 2500 years. Additionally, we revealed that coastal populations in western, eastern, and southern Africa experienced small influxes of Eurasian genes as a result of different events over the last 3000 years. These findings show that groups from similar parts of Africa experienced admixture events at similar times and involving similar sources, suggesting that genetic variation in these areas of the continent has been shaped by shared historical events. It is also clear that our ancestors have always moved about and traces of these migrations are left in the DNA of people alive today."

Livestock enclosures dating back over 6,000 years to the Ancient Neolithic have previously been documented at other sites on Spain's Sierra de Cantabria, about 300 kilometres north-northeast of Madrid, and around 100 kilometres south of the Bay of Biscay. A new study by the same team looks at ancient activities inside these shelters during the Copper Age, about 5,000 years ago.

     Ana Polo-Diaz, a researcher at the University of the Basque Country explains: "This is a piece of pioneering work in the studies on agro-pastoral communities on the Iberian Peninsula. We have evidence that the human groups that occupied San Cristobal during the Chacolithic used the shelter as a pen for goats and/or sheep and that this use, although repetitive throughout hundreds of years, was not ongoing but of a temporary nature linked to a seasonal exploitation of the rich natural resources available on the Sierra de Cantabria. We also know thanks to the microscopic study of the sediments that every now and again they used to burn the debris that had built up, probably to clean up the space that had been occupied and that this combustion process was carried out in line with some specific habits: they used to pile up the debris and on top of them pile up woody remains, perhaps to help to get the fire going before going on to burn the debris."

     Analyses of micro-sediments and mineral remains of the skeleton of plants makes it possible to determine the grazing available around the shelter. Pollen reveals that a forest grew in the immediate surroundings of San Cristobal during the period, in which hazelnut trees predominated along with deciduous oaks, and grazing areas and farmland fairly close to the shelter.

     Charcoal remains indicate a clear change in the selection of woody materials: during the oldest phase a predominance of pine followed by yew, in the latter phase increased use of species such as oak, holm oak, the rose family, and box.

     Correlating data with that from neighbouring sites and the immediate area reveals that San Cristobal was part of a network of shelters and enclosures, and the people were very likely the same ones using the dolmens of the Rioja Alavesa region.

The earliest evidence of domesticated rice has been found in China, and it's about 9,000 years old.

     Working with three researchers from the Provincial Institute of Cultural Relics and Archaeology in Zhejiang Province, China, anthropological archaeologist and University of Toronto Mississauga professor Gary Crawford found the ancient domesticated rice fragments in a probable ditch in the lower Yangtze valley, south and southwest of Shanghai. The remains document an early stage of rice domestication and the ecological setting in which early cultivation was taking place. The rice plant remains also had characteristics of japonica rice, the short grain rice used in sushi that today is cultivated in Japan and Korea - the first confirmation that it grew in this region of China.

 Archaeological evidence for the initial steps leading to domesticated rice in China is elusive.

     Crawford and his colleagues spent about three years exploring the five-hectare site, called Huxi, situated in a flat basin about 100 metres above sea level. Digging 1.5 metres below the ground, the team also unearthed sophisticated pottery and stone tools, as well as animal bones, charcoal and other plant seeds.

     This study builds on Crawford's previous research into early agriculture in China, in which he examines ancient settlements, tools, and plant and animal management efforts in different regions of the country, to better understand the transition from hunters and gatherers to farmers.

     "The question I ultimately want to answer is, what pushed them to move wholeheartedly into the farming regime? Why did they reduce their emphasis on hunting and expand into crop production?" Crawford says. "People did what they needed to do to make their lives more manageable and sustainable, and the unintended consequence was farming. With this rice discovery, we're seeing the first stages of that shift."

Paintings at Laas Geel in the self-declared state of Somaliland retain their fresh brilliance some 5,000 years or more after Neolithic artists swirled red and white colour on the cliffs of northern Somalia, painting antelopes, cattle, giraffes and hunters carrying bows and arrows.

     Abdisalam Shabelleh, site manager from Somaliland's Ministry of Tourism, says: "These paintings are unique. This style cannot be found anywhere in Africa." Then he points to a corner, where the paint fades and peels off the rocks. "If nothing is done now, in 20 years it could all have disappeared."

     Amazed by the remarkable condition of the paintings as well as their previously unknown style, Xavier Gutherz, the former head of the French archaeology team that discovered the site in 2002, asked for the cave's listing as a Unesco world heritage site, but that was refused because Somaliland is not recognised as a separate nation. "Only state parties to the World Heritage Convention can nominate sites for World Heritage status," said a Unesco spokesperson. Requests for funding from donor countries face the same legal and diplomatic headache.

     The cave paintings have become one of the main attractions for visitors to Somaliland. Around a thousand visitors each year endure rugged terrain with armed escorts to reach Laas Geel, and numbers are growing.

     Archaeologists say that Laas Geel may only be one of many treasures awaiting discovery in the vast rocky plains stretching towards the tip of the Horn of Africa.

Perfectly preserved images of humans, a bull, trees and birds - more than 20 petroglyphs found by accident years ago in a remote part of the Trans-Baikal region. Most intriguing is a human-like figure near a circle with a cross inside it. Experts kept the discovery secret for three years while they returned to study these drawings along Largi River near the village of Gorbitsa, not far from the northernmost border of China. The precise location is still not disclosed.

     Dr Sergei Alkin, from Novosibirsk University, was the first academic to closely examine the rocks, where paintings were made with red and orange ochre, an earthy pigment containing iron oxide.

     Dr Alkin says the site is rare. "It is large and contains many images, while generally on the rocks in this area show between one and three poorly preserved drawings."

Preliminary dating suggests the find is around 4,000 years old.

     "The rock art is not just paintings or engravings," Dr Alkin said. "They are associated with the rituals and ceremonies. Usually at the site under the images are the altars, there are various tools, and arrowheads. Today this place is remote and scarcely populated, but in the times when Largi rock art was created it was relatively well inhabited. In addition, we want to explore the neighbourhood in search of other petroglyphs."

     The artists are likely to have been people of Tungus or Mongolian origins. Scientists hope analysis of the composition of the ochre will help locate the source of the raw material.

A 6,500-year-old grave of a man holding in his hands a stone axe sceptre has been found by archaeologists excavating a recently discovered Copper Age necropolis in northeast Bulgaria.

     A total of seven graves were found in the necropolis of Kamenovo when it was first discovered in September 2015, however these were all graves of women and children. The newly discovered grave is the first male grave to be found there.

     The newly found grave of the male who was buried holding a stone axe dates to 4,500-4,300 BCE. Inside the grave, archaeologists also found a bead from a Mediterranean seashell. Seashell beads were also found in some of the graves discovered in 2015.

     Head archaeologist Yavor Boyadzhiev has explained that the male grave has been found in a shallow layer, almost right under the modern-day surface in the yard of a former elementary school.

     The man was buried in a fetal position, lying on his left side, holding the stone axe in his hands, with his body oriented in an east-west direction. Boyadzhiev says the bodies of women and children discovered so far were buried in a similar way, and some of the graves were organised in rows.

     Boyadzhiev says that, while the sex of the person in the newly found grave is not yet confirmed, it seems certain that he was a male because of the stone axe sceptre found in his hands: all 15 similar prehistoric stone axe sceptres to have ever been discovered in Bulgaria have been found in male graves. There are no traces that the stone axe was ever used. Its purpose was likely symbolic.

     Shortly before finding the necropolis, the same archaeological team discovered a 6,500-year-old workshop for flint tools. The team plans to continue researching the workshop, which they believe began operating in the early Copper Age, around 4,800 BCE, within a settlement. The people extracted flint from nearby deposits, processed it, and distributed the tools they produced all over the southern Balkan Peninsula.

Astronomers are exploring what might be described as the first astronomical observing tool, potentially used by prehistoric humans 6,000 years ago. They suggest that the long, narrow entrance passages to megalithic tombs may have enhanced what early human cultures could see in the night sky. A team of researchers has presented this study at the National Astronomy Meeting, in Nottingham (England).

     The team's idea is to investigate how a simple aperture, for example an opening or doorway, affects the observation of slightly fainter stars. They focus this study on passage graves, which are a type of megalithic tomb composed of a chamber of large interlocking stones and a long narrow entrance. These spaces are thought to have been sacred, and the sites may have been used for rites of passage, where the initiate would spend the night inside the tomb, with no natural light apart from that shining down the narrow entrance.

     These structures could therefore have been the first astronomical tools to support the watching of the skies, millennia before telescopes were invented. Kieran Simcox, a student at Nottingham Trent University, and leading the project, comments: "It is quite a surprise that no one has thoroughly investigated how for example the colour of the night sky impacts on what can be seen with the naked eye."

     The project targets how the human eye, without the aid of any telescopic device, can see stars given sky brightness and colour. The team applied these ideas to the case of passage graves, such as the 6,000 year old Seven-Stone Antas in central Portugal. Dr Fabio Silva, of the University of Wales Trinity Saint David, explains that, "the orientations of the tombs may be in alignment with Aldebaran, the brightest star in the constellation of Taurus. To accurately time the first appearance of this star in the season, it is vital to be able to detect stars during twilight."

     The first sighting in the year of a star after its long absence from the night sky might have been used as a seasonal marker. The timing of this could have been seen as secret knowledge or foresight, only obtained after a night spent in the depths of a passage grave, since the star may not have been observable from outside. However, the team suggest it could actually have been the result of the ability of the human eye to spot stars in such twilight conditions, given the small entrance passages of the tombs.

No game was too big to hunt for Stone Age man
A team of researchers from Tel Aviv University (Israel) have been conducting research into the consumption and possible hunting of prehistoric elephants by Palaeolithic dwellers. They studied evidence from sites across the world, ranging from the Republic of Djibouti in Africa, Valencia in Spain, the Dead Sea Rift Valley and as far east as Russia.

     To understand the scale of the logistics behind hunting and slaying an elephant we must bear in mind that the head alone, of a modern day African elephant weighs in excess of 400kg. The extinct elephant roaming the planet in the Pleistocene era was approximately twice this size.

     The head of an elephant is actually exceptional nutritious, taking together its constituent parts of brain, tongue ears and trunk, providing the correct balance required of meat and fat. There is even evidence in the Bolonar Cave in Valencia of the skull and jaw bone being crushed to extract the marrowbone.

     Great cooperation was needed, not only to kill the animal but also to transport the heads back to their campsites. One site, at Gesher Benot Ya'aqov in the Dead Sea Rift valley, had evidence of the remains of 154 elephants. The leaders of the team, Aviad Agam and Ran Barkai are quoted as saying "The repeated evidence of transportation of elephants' head parts to residential sites indicates it was chosen to be transported back."

As part of the discovery of the Dinaledi chamber and the Rising Star Cave in the Malmani dolomites, part of the Cradle of Humankind World Heritage Site in South Africa, Professor Lee Berger's team was faced with a challenge. The opening to the cave containing the 1500 Homo Naledi fossils was only 18 centimetres and lead into a 12-metre vertical chute. This led to Professor Berger to call for skinny underground astronauts to help traverse the cave.

     Using aerial drone photography, high-resolution 3D as well as other techniques, the all-female team was able to map the cave entirely and make real time descisions concerning the excavations. Kruger stated that: "This is the first time ever, where multiple digital data imaging collection has been used on such a scale, during a hominin excavation," adding that "These methods provided researchers with a digital representation of the site from landscape level right down to individual bones."

     Ashley Kruger, a PhD candidate in Palaeoanthropology at the Evolutionary Studies Institute at Wits, used the mapping technologies on site, stating, "These methods provided researchers with a digital representation of the site from landscape level right down to individual bones," says Kruger.

     Homo naledi is an extinct species of hominin, assigned by the anthropologists to the genus Homo, found the Rising Star Cave by recreational cavers Rick Hunter and Steven Tucker in 2013.

     Kruger's publication has already come out in the South African Journal of Science, with a number of papers planned for publishing. The research will continue on site, hoping to answer the question of how the site was formed, if anything can be gained from fossil positioning, as well as answer how the bodies came to the cave.

In Europe, the oldest boat ever discovered is a 10,000 year-old dugout canoe from the Netherlands.

The oldest plank-built vessels in the region are Bronze Age boats found at Dover and in Yorkshire, dated to between 3,500 and 4,000 years ago. At Bouldnor Cliff, 11 metres underwater off the northwest shore of the Isle of Wight in the south of England, Garry Momber and the Maritime Archaeology Trust have found something up to twice that age.

     In 2005, at the bottom of a 7-metre high underwater cliff, Garry saw something. "Among the branches of an old tree was a collection of coloured flints, some of which had been superheated."

     Two years later the team had enough money to investigate further. Their 2 by 3 metre excavation revealed charcoal, flint tools, wood chippings, well-crafted functional items, and dozens of pieces of well-preserved timbers. Most of the timbers were oak, still in position where they had fallen over 8,000 years ago. Some had been shaped and trimmed, while others had been charred to make them easier to work.

     One piece, just under 1 meter long and about 8,100 years old, had been split - a technique which doesn't appear elsewhere in the British archaeological record for another 2,500 years, when it was used during the Bronze Age to build deeper log boats, by removing 1/4 of the tree and hollowing out the remaining 3/4.

     When it was felled, the tree would have been a couple of metres wide and several tens of metres high.

     The team also found a scalloped out end-piece, timbers that formed the end of the structure, and cord which would have united the various elements. Taken together, these would make Bouldnor Cliff the oldest known boat-building site in the world. "The trouble is we still need more evidence to be 100% certain," says Garry.

     Garry and his team will return to the site in June. You can follow their progress at DigVentures on Facebook, and TheDigVenturers on Twitter.

Scientists from the India Institute of Technology in Kharagpur, and the Archaeological Survey of India, have uncovered evidence that the Indus Valley Civilisation is at least 8,000 years old, and that pre-Harappan civilisation existed for at least 1,000 years before this. They also believe climate change ended the civilisation about 3,000 years ago.

     Anindya Sarkar, head of the department of geology and geophysics at IIT-Kharagpur, says: "We have recovered perhaps the oldest pottery from the civilisation. We used a technique called 'optically stimulated luminescence' to date pottery shards of the Early Mature Harappan time to nearly 6,000 years ago and the cultural levels of pre-Harappan Hakra phase as far back as 8,000 years."

     The team's excavations at an unexplored site - Bhirrana - also yielded large quantities of animal remains like bones, teeth, and horn cores of cow, goat, deer and antelope.

     The researchers believe that the Indus Valley Civilisation spread over a vast expanse of the sub-continent. While earlier phases were represented by pastoral and village farming communities, and mature Harappan settlements were highly urbanised with organised cities, a developed material and craft culture, and regular trade with Arabia and Mesopotamia, the Late Harappan phase is characterised by large-scale de-urbanisation, drop in population, abandonment of established settlements, lack of basic amenities, violence, and even the disappearance of the Harappan script.

     The study shows that the pre-Harappan humans started inhabiting this area in a climate favourable for settlement and agriculture.

     "The monsoon was much stronger between 9000 years and 7000 years ago, and probably fed these rivers making them mightier with vast floodplains," explains Arati Deshpande Mukherjee of Deccan College, which helped analyse the finds.

     The researchers say that, with the declining monsoon, the Indus Valley people shifted their crop patterns from large-grained cereals like wheat and barley to drought-resistant species like rice. As the yield diminished, the organised storage system of the Mature Harappan period gave way to more individual household-based crop processing and storage systems, acting as a catalyst for the gradual decline of the civilisation rather than any abrupt collapse.

Spanish archaeologists say they have discovered an exceptional set of Palaeolithic cave drawings that could rank among the best in a country which already boasts some of the world's most important cave art.

     Chief site archaeologist Diego Garate says that an estimated 70 drawings were found on ledges 300 meters underground in the Atxurra cave in the northern Basque region, describing the site as being among the top 10 in Europe. The engravings and paintings feature horses, buffalo, goats, and deer, dating to between 12,500 and 14,500 years ago.

     Garate says access to the area is so difficult and dangerous that it is unlikely to be open to the public.

     The cave was discovered in 1929 and first explored in 1934-35, but it was not until 2014 that Garate and his team resumed their investigations and the drawings were found.

     "No one expected a discovery of this magnitude," said Jose Yravedra, a prehistory professor at Madrid's Complutense University. "There a lot of caves with drawings but very few have this much art and this much variety and quality."

     Garate says one buffalo drawing depicts what must be the most hunting lances of any in Europe. Most have four or five lances but this has almost 20.

     Yravedra says that, given the cave's hidden location and the number, variety, and quality of its drawings, the site was being classified as a "sanctuary," or special Palaeolithic meeting ritual place, like those at Altamira in Spain, or Lascaux in France.

     Regional officials hope to set up a 3-D display of the art so that the public can appreciate it.

A team of researchers, headed up by the Tel Aviv University (Israel), has recently been studying animal remains fund in a cave known as the Qesem Cave, located 12 km from Tel Aviv.

     Human occupation of the cave was first identified in 2010 and is recorded as having started approximately 400,000 years ago and covered a span of 200,000 years. Whilst it is widely known that early humans captured, cooked and ate large game (in addition to a vegetarian diet), the discovery made by the team indicates that turtles also formed a significant part of their diet. Whilst not being as nutritious as larger game, the turtles nevertheless provided substantial calorific value, enough to warrant the time and effort needed in their capture, transport and preparation.

     Studies of the remains found indicate that there were two main ways of cooking these heavily armoured creatures, either by roasting whole within the shell or by splitting the shell open with flint tools and roasting the flesh on its own. As turtle remains were found at most levels throughout the cave it is thought that they must have been part of the diet throughout the 200,000-year human occupation.

     Doctor Ruth Blasco, a leading member of the team, is quoted as saying "In some cases in history, we know that slow-moving animals like tortoises were used as preserved or canned food. Maybe the inhabitants of Qesem were simply maximising their local resource. In any case, this discovery adds an important new dimension to the knowhow, capabilities and perhaps taste preferences of these people"

A team of archaeologists from the University of Colorado at Boulder (USA) have been investigating one of the reasons why the giant flightless ancestor of the Emu may have been driven to extinction. The bird in question is the Genyornis newtoni, which grew to over 2 metres high an d weighed between 220 and 240 kilogrammes.

     It roamed the Australian continent 50,000 years ago, at a time when it is believed that the early humans arrived. It would appear that these early humans had developed a taste for the unfortunate bird's eggs, thus playing a significant part in their decline by restricting their reproduction.

     The evidence for this claim was found in the analysis of burnt eggshell fragments. First the eggs were dated using optical stimulated luminescence dating technique, which was corroborated by radiocarbon dating. Then the burnt sections were analysed by studying the amino acid decomposition, which proved that the burning could not have been caused by natural wildfire, but was more concentrated and deliberate.

     Professor Gifford Miller, Associate Director at Colorado University, is quoted as saying "We consider this the first and only secure evidence that humans were directly praying on now-extinct Australian megafauna. We have documented these characteristically burned Genyornis eggshells at more than 200 sites across the continent".

Archaeology in the United States of America is sometimes conducted in an unusual way. In this instance the archaeologists were working for a commercial organisation known as Logan Simpson who, in addition to specialising in landscape architecture and environmental services, also employ cultural resource consultants who carry out what they call, Historic Archaeology.

     Using a technique known as Predictive Modelling they identified an area in Southern Nevada (known as the Great Basin) which was found to house 19 separate sites from the Paleoarchaic Period, which stretched from 10,000 BCE to 5,000 BCE, marking the transition from Pleistocene to Holocene Eras. By studying already known sites from this period they predicted where others might be found.

     Previous usage of this technique resulted in uncovering previous unknown human settlements in Wyoming. Predictive Modelling utilises statistical data to predict outcomes and has been successfully deployed to detect crimes and identify the criminals, as well as many other fields, although there have been some spectacular failures in the financial sector, particularly in 2008.

     Jesse Adams, the archaeological team leader for Logan Simpson, is quoted as saying "The Pleistocene-Holocene Transition is a fascinating, yet under represented, time period in the Great Basin. Through the creation, and later revision, of a predictive model using GIS technology, we are able to successfully identify archaeological sites from this time period on the landscape."

Heritage experts will examine the complex role of Old Oswestry's landscape through the ages at a forthcoming seminar dedicated to one of Britain's most spectacular and impressive early Iron Age hill forts in the Welsh Marches near Oswestry in north west Shropshire.

     Entitled 'A Wider Understanding of Old Oswestry and its Setting', this is the second seminar organised by campaign group HOOOH as it continues to fight development targeting the hillfort's ancient landscape. Speakers include hillfort and prehistory specialist, Dr Rachel Pope of the University of Liverpool, who will make the case that the setting of hillforts should now be recognised as a heritage protection concern.

     Prehistoric finds in North Shropshire, as reported to the Portable Antiquities Scheme (PAS), are the focus of Peter Reavill's presentation as he discusses what they reveal of the County's wider archaeological landscape. Hillfort researcher, David Matthews, will provide analysis of the intervisible links and tribal connections between Old Oswestry and the hillforts of the Northern Marches. Heritage planning expert, Tim Malim, will examine how location, ancient routes and trading links helped define the importance of Old Oswestry in the Medieval period. Folktales and legends of the landscape come under the scrutiny of archaeologist, Caroline Malim, as she asks whether archaeology can unlock the truth or fiction behind them.

     Free to attend, the day-long seminar takes place on February 13 from 10am to 4.15pm in Oswestry's Memorial Hall in Smithfield Street. It forms the keynote to a weekend of activities devoted to Old Oswestry running February 13 and 14, culminating with a hillfort hug on Valentine's Sunday.

Genetic relationships between human groups were first studied by comparing populations - an approach having problems of resolution and dating, but results were largely consistent with an African ancestry for anatomically modern humans (AMH). Following specific lineages rather than populations has since revealed a detailed geography of migrations, revolutionising our knowledge of the peopling of the world, giving stronger proof of the recent near replacement of all human species by AMH.

     Africa is the most likely geographical origin for a modern human dispersal. The basic questions are how many founding exits of AMH can be seen in the fossil or archaeological record, which of these are evidenced genetically, which routes were taken, and when, how, and why.

     There is growing consensus for a single southern dispersal of AMH via the mouth of the Red Sea, around the coasts of the Indian Ocean - initially to Bali, but ultimately to Melanesia and Australia, and to the Americas.

     Although evidence for a single successful ex-African AMH lineage is clear, the scenario is surprising and counterintuitive. In the absence of severe drift, a single exit group would be expected to involve multiple founder lineages spreading to different Eurasian locations.

     A single successful African exit for AMH has several implications. The simplest but most important is that the number of possible subsequent routes decreased. Whichever route was taken initially, the model has to explain how both Europe and Asia could have been colonised from the same single exit group.

     There are genetic reasons for identifying the southern route across the mouth of the Red Sea as the most likely. Dated archaeological evidence for the exit is lacking, because sea-level rise has drowned most coastal remains. Much of the relevant datable evidence lies either in on the Indian subcontinent, or on the eastern side of the Indian Ocean. The first archaeological evidence of occupation of the island of New Guinea has been radiocarbon dated to 49,000 BP.

In the Nefud Desert of northern Saudi Arabia, large sandstone outcrops diverted the flow of sand, allowing lakes and marshes to form several times in the past, and evidence has been found for repeated human occupations extending back hundreds of thousands of years.

     The Arabian Peninsula saw some of the earliest human migrations, yet until just five years ago not a single Palaeolithic site had been excavated or dated. Recent excavations in the United Arab Emirates and Yemen have confirmed early human occupations, yet most of the Peninsula remains almost unknown.

     Ancient lakes provide significant evidence for environmental change in Saudi Arabia. There are hundreds, if not thousands, of these lakes. By analysing sediments and associated materials such as fossils, we can draw a detailed picture of the local climate. Few other places on earth saw such dramatic changes, but we have yet to see whether early humans took advantage of broad windows of opportunity in the Early Pleistocene and the earlier part of the Middle Pleistocene.

     In Africa, Homo erectus began to produce hand axes about 1.8 million years ago, in the Acheulean period. In Arabia hand axes are often found at the source of the raw material and adjacent to ancient lakes. The abundance of Late Acheulean material suggests that relatively dense occupations occurred in the later interglacials of the Middle Pleistocene.

     In the East Mediterranean Levant, the transition from the Lower to the Middle Palaeolithic occurs about 250,000 years ago, with an abrupt change in material culture often attributed to population replacement. Though this transition occurs at different times around the world, research in Saudi Arabia suggests that in the north the change happens at the same time as in the Levant. We see significant technological innovations, a shift from handheld tools to hafted tools, and a substantial increase in imported raw materials. However it appears that Middle Palaeolithic occupations were as short-lived as those of earlier periods. In the Middle Palaeolithic (circa 250,000 to 40,000 years ago) there is considerably greater variation in stone-tool technologies.

     The early phases of the Middle Palaeolithic remain poorly understood. The era between about 130,000 to 75,000 years ago has produced a far larger body of finds in Arabia. This is the period when we see evidence for the earliest expansion of Homo sapiens out of Africa and into the Levant, generally regarded as a failed dispersal.

     No archaeological sites are currently known for the period of around 70,000-60,000 years ago. The next wave of human occupation occurred about 60,000 to 55,000 years ago, still associated with a Middle Palaeolithic technology broadly similar to tools produced at this time by Neanderthals in the Levant. The youngest known Middle Palaeolithic assemblages in Arabia, dating to around 40,000 years ago, are found in the United Arab Emirates. There is then a complete absence of human occupation across the Peninsula until the transition to the Holocene, about 12,000 years ago.

     Major debate surrounds the process by which the Neolithic way of life developed in Arabia: was it imported from the Levant, or of indigenous origin? Evidence from stone tools and rock art which date to the earliest phases of this period suggest a bit of both - not simple population dispersal, but rather of some form of cultural diffusion.

     At the remarkable site of Shuwaymis, 'Neolithic' rock art reflects at least two phases. The first is associated with hunter-gatherers, often showing horses, hunting dogs, and human figures with bows. The second shows cattle, but no hunting scenes, and the pastoralists selectively re-engraved some of the earlier hunter-gatherer images. For example, humans were sometimes re-engraved, but the bow and arrows they were holding were not. Along with findings from southern Arabia, this suggests both continuity and change: Arabia was not simply an empty space into which people moved.

Archaeologists say they have uncovered Britain's 'Pompeii' after discovering the best-preserved Bronze Age dwellings ever found in the country. The circular wooden houses, built on stilts, form part of a settlement at Must Farm quarry, in Cambridgeshire (England), and date to about 1000-800 BCE. A fire destroyed the posts, causing the houses to fall into a river where silt helped preserve the contents. Pots with meals still inside have been found at the site.

     An earlier test trench at the site, near Whittlesey, revealed small cups, bowls and jars. In addition, archaeologists said 'exotic' glass beads that formed part of a necklace "hinted at a sophistication not usually associated with the Bronze Age". Textiles made from plant fibres such as lime tree bark have also been unearthed. However, the roundhouses themselves are now being excavated.

     Archaeologists think they have found about five houses but are not yet certain. The work to uncover the settlement is necessary because there are concerns the water level at the site could fall some time in the future, meaning the remains of the houses cannot be preserved in situ.

     Duncan Wilson, chief executive of Historic England, described the settlement and contents as "an extraordinary time capsule". He added: "A dramatic fire 3,000 years ago, combined with subsequent waterlogged preservation, has left to us a frozen moment in time, which gives us a graphic picture of life in the Bronze Age."

     David Gibson, from Cambridge Archaeological Unit, which is leading the excavation, said: "So much has been preserved, we can actually see everyday life during the Bronze Age in the round. It's prehistoric archaeology in 3D, with an unsurpassed finds assemblage both in terms of range and quantity."

     Well-preserved charred roof timbers of one of the roundhouses are clearly visible, together with timbers showing tool marks and a perimeter of wooden posts known as a palisade, which once enclosed the site. Archaeologists digging 2m (6ft) below the modern surface at the quarry also found preserved footprints, believed to be from people who once lived there.

     While a number of Bronze Age settlements have been found in the UK, Mr Gibson said none had been as well-preserved as the Must Farm site. "Most don't have any timber remaining, just post-holes and marks where posts would have been," he said. "So far this is unique as we have the roof structure as well."

The 2,500 year old footprints of some ancient farmers and their children and dogs have been found perfectly preserved north of Tucson, Arizona (USA), roughly 800 kilometres east-southeast of Los Angeles. Dozens of prints depict the movements of several adults and at least one child, as they tended their crops and irrigation ditches. They are likely the oldest human tracks yet found in the North American Southwest.

     The barefoot tracks are distinct enough that the movements of specific individuals can be followed across the 15-square-meter field. The tracks were preserved by a sudden flood from a nearby creek soon after the prints were made, covering them in mica-rich sandy sediment, forming a kind of mineralised cast.

     The fields appear to date to the Early Agricultural Period, a span between about 2500 BCE and 50 CE when some of the Southwest's first farmers began cultivating crops.

     The fields, the shallow ditches around them, and even the small depressions where archaic farmers placed individual plants of corn and other crops may stretch far and wide throughout the area, says Jerome Hesse, project manager for SWCA Environmental Consultants, which is conducting the study, "So we've excavated a number of these planting depressions and will run samples for pollen and phytoliths to get a sense of what was being grown."

     The nonprofit 'Archaeology Southwest' is conducting 3-D photo scans of the site to create a digital model, and some of the prints have been cast with synthetic moulds, while others have been extracted completely to be sent to nearby museums. The site lies in the path of road construction.

Three years of work has gone into creating a true-to-life replica of renowned Stone Age cave paintings in southwestern France, and the 46 segments are ready to be transported and installed in a hillside near the original site in Montignac, in the Dordogne, about 500 kilometres south-southwest of Paris. The International Centre of Parital Art, 150 metres long and 9 metres high, will open by the end of the year.

     The original cave, discovered in 1940 and closed to the public since 1963, contains nearly 2,000 Upper Palaeolithic wall paintings depicting rhinos, horses, bison, deer and panthers - Europe's most important collection of prehistoric art, by the oldest known modern humans, who came to Europe from Africa via Asia.

     A limited set of reproductions have been on display since 1983. The 57 million-euro project to replicate the entire set unites technology with a desire for the utmost authenticity.

     Francis Ringenbach, the artistic director of the project and himself a sculptor, says the need to be as faithful as possible to the original slowed the team down. "Sometimes one has to spend hours reproducing just 10 square centimetres," he says.

     The artists benefitted from 3D digital scans of the original paintings that were projected onto the walls, creating a task akin to using tracing paper as they applied layer upon layer of natural pigments. Chief painter Gilles Lafleur said of the original works: "We try to understand them really, to understand how and why they were painted this way," but admits that "time has taken its toll and these animals don't look the way they would have when they were painted."

     Ringenbach says that where the smaller-scale original museum offered limited insight into the site's significance, "here, we reach a whole new level in terms of helping people to understand what Lascaux represents for science, the history of art, prehistory."

The Neolithic people are thought to have introduced new burial rituals - including megalithic tombs, which were used over an extended period of time as sites for collective burials and ritual acts. Complex patterns of treating and reburying skeletal remains have been identified in some tombs.
     The analysis of the human remains from the strikingly situated 3 metre diameter tomb at Alto de Reinoso, 250 kilometres north of Madrid, represents the widest integrative study of a Neolithic collective burial in Spain - a good example of a non-megalithic barrow. Combining archaeology, osteology, molecular genetics, and stable isotope analysis, the study provides information on the number of individuals, as well as their age, sex, body height, diseases, injuries, mitochondrial DNA profiles, kinship relations, mobility, and diet.

     The grave was in use for approximately one hundred years around 3700 BCE - the Late Neolithic in Iberia. Findings suggest the tomb probably began as a burial chamber made of wood, mud, and other organic materials, which was later dismantled and converted to a monumental structure by erecting a stone mound over it.

     The uppermost Bronze Age layer, containing the remains of two individuals from around 1700 to 1500 BCE and disturbed by agricultural activity, is not included in the study. Beneath that, further bodies represented a different use of the tomb, with almost all of those skeletons missing bones, especially skulls. At the bottom, on natural bedrock, six complete and six partial skeletons lay in crouched positions.

     In total the Neolithic burials comprise at least 47 individuals - a surprisingly high density - including males, females, and adolescents, although children aged 0 to 6 years were under-represented. The remains exhibit a moderate number of pathologies, such as degenerative joint diseases, healed fractures, head injuries, and tooth decay.

     Mitochondrial DNA profiles reveal a closely related local community with matrilineal kinship. In some cases adjacent individuals in the bottom layer showed familial relationships. According to their strontium isotope ratios, only a few were likely to have spent their early childhood in a different geological environment - the majority grew up locally. Carbon and nitrogen isotope analysis indicate a homogeneous group with egalitarian access to food. Cereals and small ruminants - possibly sheep and goats - were the principal sources of nutrition: a lifestyle typical of sedentary farming populations in the Spanish plateau during this period of the Neolithic.

     Artefacts were not abundant, but include both personal adornments such as stone necklace beads and wild boar tusk pendants, as well as grave goods such as polished stone axes, flint blades and microliths, and bone scrapers. There was a distinct lack of pottery in megalithic tombs, at least during the earlier period of their use.

     The Neolithic tombs in Europe represent a particular type of collective burial. Communal use clearly illustrates the bond within a community where the individual is not at the forefront, in life or in death. It was not until the Copper and Bronze Ages that social differentiation increased, and individuals and groups came to the fore.

Two independent studies, both recently published in the American Journal of Human Genetics, have both confirmed the belief that interbreeding between two of our ancestors, namely Neanderthals and Denisovans, has directly contributed to improvements to our immune system but at the expense of increasing our susceptibility to allergies. The two studies were carried out by the Max Planck Institute for Evolutionary Anthropology (Leipzig) and the Institut Pasteur and the CNRS (Paris).

     The team from the Institut Pasteur studied data on modern humans, gleaned from the large amount of data provided by the 1000 Genomes Project (This was a worldwide project, started in 2008, to build up a catalogue of human genetic variation). They compared this data against the genetic makeup of Neanderthals and Denisovans, identifying where and when the genetic modifications occurred.

     The Max Planck team had concentrated on a study of the importance of inherited genes but identified exactly the same genes as the French team. Janet Kelso, from the Max Planck team, is quoted as saying "What has emerged from our study as well as from other work on introgression is that interbreeding with archaic humans does indeed have functional implications for modern humans and that the most obvious consequences have been in shaping our adaptation to our environment - improving how we resist pathogens and metabolize novel foods". She went on to add "Neanderthals, for example, had lived in Europe and Western Asia for around 200,000 years before the arrival of modern humans. They were likely well adapted to the local climate, foods and pathogens. By interbreeding with these archaic humans we modern humans gained these advantageous adaptations".

A 7,000-year-old defensive wall from the Copper Age has been discovered at a prehistoric settlement mound near Hotnitsa, in north central Bulgaria. The palisade was made of wooden pillars 40 centimetres in diameter, and plastered with clay on both sides. The finished wall surrounding the 50 metre diameter settlement was about 80 centimetres wide, probably up to 3 metres tall, and maintained for 1,000 years.

     The settlement was inhabited from the 5th to 4th millennium BCE by people engaged in agriculture, cattle breeding, hunting and gathering. Discovered in 1955, its archaeological layers are 6 metres thick. It is known for the Hotnitsa Gold Treasure, from the same period as the gold treasure from the Varna Chalcolithic Necropolis on the Black Sea. One of the gold spirals found at Hotnitsa was more than a metre deeper than any from Varna, and could be the world's oldest gold.

     In a small pit under the floor of a burned home with well-preserved charred wood, the team found a hand mill, a ceramic vessel, and two flint artefacts. The pit was dug before the home was built. A pit previously discovered beneath a different home on this site yielded a collection of legs from goats, sheep, and pigs, placed in an anatomically correct order. A pit plastered into the floor of a home in another settlement held a model of a miniature vessel. A pit within a home in a third settlement contained a large vessel with ashes.

     Large finds from 2015 at Hotnitsa include a section of 6,400-year-old wooden floor, preserved by a flood. The boards fit perfectly together, supported by beams about one metre apart. Small finds comprise some 500 artefacts, mostly flint tools made from prime quality flint from northeast Bulgaria. Other tools include a bone dagger, a copper needle, stone claw hammers, awls, and arrow tips. Ceramic vessels, and ornaments made of bone or the shells of freshwater mollusks and snails were also found. Among the most interesting artefacts is a vertical loom for weaving.

     Truly remarkable is a 6,400-year-old ceramic vessel lid with a depiction of a male head with a large nose and a pointy chin. Signs shaped like butterflies, possibly tattoos, are visible on the man's cheeks. He wears a small cap represented with by dots. Archaeologist Alexander Chohadzhiev says: "This is a very rare find because the anatomical features of the face are presented in great detail. We have found other depictions of male heads with beards but the presence of a cap shows that this man enjoyed a more special status. In the past, we have found a similar lid in Petko Karavelovo - a male head with beard braids wearing the same kind cap but it was depicted with spirals, not dots.

     His team has also found two bone figurines with female human features, one of them 8.5 millimetres long and only 3 millimetres wide. Another new find is a miniature model of a ceramic vessel - the second of its kind found at Hotnitsa.

     Excavations first took place at Hotnitsa between 1956 and 1959. Finds included 20 perfectly aligned thatched roof one-room homes made with wooden poles plastered with mud, as well as ceramic vessels, and artefacts made of copper, bone, stone, and flint. In one home, archaeologists found 40 gold rings, and four thin gold plates with depictions of faces drawn with dots. In another were found a large quantity of prehistoric idols made of bone, not all of them finished. From 2000 to 2007, the northern half of the mound yielded 6 more homes and over 5,000 artefacts, including gold items, copper tools, and figurines of humans and animals.

     Some artefacts are interpreted as proving Hotnitsa had commercial ties with the Black Sea, the Mediterranean, and north of the Danube.

     The settlement may have been destroyed in an invasion of nomadic tribes from the north, who, after 800 years of convergence with the local population gave rise to the highly developed civilisation of Ancient Thrace.

The first log boats are thought to predate both pottery and agriculture by thousands of years. During the Bronze Age, which lasted from roughly 2000 BCE to 500 BCE in Northern Europe, log boats began to change. According to Ole Thirup Kastholm, of Denmark's Roskilde Museum, the changing designs reflect broader cultural transformations.

     Examining 110 log boats recovered from sites in Scandinavia, western Europe, Britain, and Ireland, Kastholm says that starting around 2000 BCE log boats from across this vast region begin to display similarities in design. Logs were carved to have slender, vertical sides and flat bottoms that made them more stable. Many were more than 10 metres long, and some were as long as 15 metres.
     Around the same time, plank boats begin to appear. Larger and more stable than log boats, they were mainly used for ocean voyages. Traditionally, archaeologists have considered Bronze Age plank boats an exclusively British design, but Kastholm thinks plank boat technology was likely more widespread. He says the similarities between log boats found throughout western and Northern Europe shows that there was a great deal of contact between people separated by vast distances.

     The plank boats and log boats being built in northern Europe were not the most advanced watercraft of their time. Greeks, Egyptians, and other cultures around the Mediterranean Sea used sailing ships. Sails wouldn't be used in Northern Europe until the Iron Age, during the 7th or 8th century CE.

     When sails did arrive in the north, instead of copying Mediterranean designs, early Scandinavian boat builders adapted their Bronze Age plank boats. Kastholm shows that Northern European Iron Age sailing ships used the same type of cleats to secure the planks to the boat frame as the earler Bronze Age plank boats. This counters the prevailing view that the Iron Age boats came from a completely different boat building tradition. If correct, this means the Northern European tradition that produced the Viking longships had its roots in the Bronze Age plank boats.

A team of archaeologists from Iran's Research Institute for Cultural Heritage and Tourism has been carrying out extensive research in the Kavousiyeh hills in Tehran's suburbs. The area had not previously been investigated to any great degree, but has now been yielding up a plethora of Bronze Age and Iron Age artefacts.

     Tehran had remained a relatively small settlement until the late 18th century, when it was chosen to be the capital city. More recent expansion had started to threaten rare archaeological sites, including this one.

     The leader of the team, Maryam Molaei is quoted as saying "Kavousiyeh hills site has been added to the list of prehistoric sites with settlement during a research investigating land downdraft in Tehran; since then no serious archaeological investigation addressed the hills, effectively putting into abeyance valuable information imbedded in the hills strata. Our present research addresses this lack".

     She went on to say "In investigation of Kavousiyeh hills modern cutting-edge technology of drone-aided imaging robot has been used; aerial photogrammetry helped also preparation of a highly precise topographic map of the hills; we currently hope to see further investigation which would address the exact area of the settled hills during prehistory and draft a set of regulations to prevent the delimitation of the hills".

Evidence is emerging that the origins of farming in Europe can be traced back to Anatolia in modern day Turkey. Occupation of the area stretches back to the Palaeolithic Era and it is also conjectured that the Indo-European language group also originated here.

     A group from the Archaeological Research Laboratory, Stockholm University (Sweden), has been studying the DNA of human remains found within the area known as Kumtepe, close to the site of Troy and also renowned for being the oldest permanent settlement in the area. Although the group has yet to publish their findings, the initial results are leading them to believe that this area was at the heart of the transition to farming.

     Team leader Jan Stora, associate professor in osteoarchaeology, is quoted as saying "It is complicated to work with material from this region, it is hot and the DNA is degrading. But if you want to understand how the process that led from a hunter gatherer society proceeding to a farming society, it is this material that we need to exhaust".
