The recent archaeological finds along the western seaboard are creating great excitement among locals, but a Clifden-based archaeologist believes much of its value will be lost if resources aren’t put into recording and interpreting the artefacts.
“There is great excitement in the local population about this [previously] drowned landscape. I am contacted virtually every day by people finding things in the fields adjoining the coastline,” says archaeologist Michael Gibbons, who wants the Government to establish regional archaeological units to record and interpret these finds.
“The problem is that if nothing is done, it will be taken back by the sea,” says Gibbons, who suggests that some of the 6,000-year-old stone axes and other prehistoric materials have already been washed away.

Visit Stonehenge in 3D on Your iPhone/iPad with Apple Maps


If you’re strapped for cash but dying to check out Stonehenge up close, there’s now an easy way to visit the prehistoric monument right from the comfort of your couch and provided that you own one of Apple’s fancy iDevices.

Stonehenge is now accessible from Apple Maps in 3D Flyover, which means you can hover over the mysterious ring of standing stones, pinch to zoom, and rotate at will to check it out from all angles.

Don’t expect to see the pores in the monoliths, though (not that they’d let you even if you were there in person). In case you’re a stranger to Apple Maps (nobody blames you), all you need to do is launch the app, tap the search bar at the top, type in “Stonehenge,” and then select the 3D Flyover view from the row of options at the bottom (represented by a trio of skyscrapers in space view).

Go ahead and give it a try on your device, then come back to read some more about Stonehenge if you’re hungry for a late history lesson on Britain’s heritage.

New Genetic Findings About Stone-Age Scandinavian Farmers and Hunter-Gatherers


An international team led by researchers at Uppsala University and Stockholm University reports a breakthrough on understanding the demographic history of Stone-Age humans. A genomic analysis of eleven Stone-Age human remains from Scandinavia revealed that expanding Stone-age farmers assimilated local hunter-gatherers and that the hunter-gatherers were historically in lower numbers than the farmers. The study is published, ahead of print, in the journalScience.

The transition between a hunting-gathering lifestyle and a farming lifestyle has been debated for a century. As scientists learned to work with DNA from ancient human material, a complete new way to learn about the people in that period opened up. But even so, prehistoric population structure associated with the transition to an agricultural lifestyle in Europe remains poorly understood.

An international team led by researchers at Uppsala University and Stockholm University reports a breakthrough on understanding the demographic history of Stone-Age humans. A genomic analysis of eleven Stone-Age human remains from Scandinavia revealed that expanding Stone-age farmers assimilated local hunter-gatherers and that the hunter-gatherers were historically in lower numbers than the farmers. The study is published today, ahead of print, in the journal Science.

The transition between a hunting-gathering lifestyle and a farming lifestyle has been debated for a century. As scientists learned to work with DNA from ancient human material, a complete new way to learn about the people in that period opened up. But even so, prehistoric population structure associated with the transition to an agricultural lifestyle in Europe remains poorly understood.
"For many of the most interesting questions, DNA-information from people today just doesn't cut it, the best way to learn about ancient history is to analyze direct data—despite the challenges", says Dr. Pontus Skoglund of Uppsala University, now at Harvard University, and one of the lead authors of the study.

"We have generated genomic data from the largest number of ancient individuals" says Dr. Helena Malmström of Uppsala University and one of the lead authors. "The eleven Stone-Age human remains were between 5,000 and 7,000 years old and associated with hunter-gatherer or farmer life-styles" says Helena Malmström.

The discovery of a mysterious copper artefact at a Neolithic tomb on Anglesey could help to answer one of  archaeology’s burning questions.
Dr George Nash, who led the excavation at Perthi Duon near Brynsiencyn, says the find could lend  weight to the idea of a British Copper Age, which is currently being  debated by archaeologists.
Perthi Duon – described by Dr  Nash as Anglesey’s “least known  Neolithic chambered tomb” – is believed to have been a portal dolmen,   a type of single-chamber tomb  mostly built in the early Neolithic  period, and dates to around 3,500BC  or earlier.

Flint tools dated 14,000 years ago


Primitive tools dug up by archaeologists in South Lanarkshire have been dated at 14,000 years old - making them the earliest evidence of humans in Scotland.
The discovery follows a study of more than 5,000 flint artefacts recovered from fields at Howburn, near Biggar, from 2005 to 2009.
Experts observed striking similarities to previous finds in northern Germany and the south of Denmark, helping them date the tools to the very earliest part of the late-glacial period.
They now believe Howburn is likely to have hosted the very first settlers in Scotland.

Log boat dating back 4,500 years found in Lough Corrib


A 4,500-year-old log boat is among 12 early Bronze Age, Iron Age and medieval craft that have been located in Lough Corrib, along with several Viking-style battle axes and other weapons.
The vessels were discovered by marine surveyor Capt Trevor Northage while mapping the western lake to update British admiralty charts.
Investigative dives were subsequently carried out last summer by the underwater archaeology unit (UAU) of the National Monuments Service, and radiocarbon dating of samples was then conducted.
Minister for Arts, Heritage and the Gaeltacht Jimmy Deenihan, who was informed of the finds recently, has described them as “exceptional”.
The three Viking-style battle axes recovered from one of the vessels will be a centrepiece in the National Museum’s Battle of Clontarf commemorative exhibition, which is due to open later this month.

Leicester dig unearths Iron Age mint and Roman tile with dog paw prints


unearthed: The Roman tile with possible dog paw prints


Archaeologists believe they might have stumbled across an Iron Age mint which produced gold and silver coins for the coveted Hallaton Treasure.
The dig at Blackfriars, in the city, unearthed coin mould fragments which, combined with evidence from previous excavations, seems to confirm the site was a 2,000-year-old Corieltauvi tribe mint.
The Corieltauvi controlled most of the East Midlands, with Leicester as its capital.
Archaeologists believe the Blackfriars site could have produced some of the 5,000 silver and gold coins found in 2000, near the Leicestershire village of Hallaton.

Researchers say Neanderthals were no strangers to good parenting


Archaeologists at the University of York are challenging the traditional view that Neanderthal childhood was difficult, short and dangerous.

A research team from PALAEO (Centre for Human Palaeoecology and Evolutionary Origins) and the Department of Archaeology at York offer a new and distinctive perspective which suggests that Neanderthal children experienced strong emotional attachments with their immediate social group, used play to develop skills and played a significant role in their society.

The cliff-hanging cists of Arran


In March 2012, the landowner and a local resident spotted a short stone cist exposed in the cliff face of a disused quarry at Sannox on the Isle of Arran. They alerted the West of Scotland Archaeology Service, which prompted Historic Scotland to commission GUARD Archaeology to undertake a rescue excavation.

A GUARD Archaeology team, led by Iraia Arabaolaza, were sent to investigate the site; not an easy task given the high exposed location of the cist. The first thing the team did was to clean the exposed section of the eroding face of the sand cliff using a mechanical cherry-picker. This revealed not just the one but two cists. The subsequent excavation of the cists required the GUARD Archaeologists to wear harness and be tied to a fixed point at all times. However, the team successfully recovered and recorded the archaeological remains and brought them back to GUARD Archaeology's laboratory in Glasgow for specialist analyses, which has only just now been completed.

Farming Changed Human Bones, Suggests Study


Because the structure of human bones can inform us about the lifestyles of the individuals they belong to, they can provide valuable clues for biological anthropologists looking at past cultures. Research by Alison Macintosh, a PhD candidate in Cambridge University's Department of Archaeology and Anthropology, shows that after the emergence of agriculture in Central Europe from around 5300 BC, the bones of those living in the fertile soils of the Danube river valley became progressively less strong, pointing to a decline in mobility and loading.

Macintosh presents some of her results at the Annual Meeting of the American Association of Physical Anthropologists in Calgary, Alberta on April 8-12, 2014. Her research shows that mobility and lower limb loading in male agriculturalists declined progressively and consistently through time and were more significantly affected by culture change in Central Europe than they were in females.

New method confirms Humans and Neandertals interbred


Technical objections to the idea that Neandertals interbred with the ancestors of Eurasians have been overcome, thanks to a genome analysis method described in the April 2014 issue of the journal Genetics. The technique can more confidently detect the genetic signatures of interbreeding than previous approaches and will be useful for evolutionary studies of other ancient or rare DNA samples.

"Our approach can distinguish between two subtly different scenarios that could explain the genetic similarities shared by Neandertals and modern humans from Europe and Asia," said study co-author Konrad Lohse, a population geneticist at the University of Edinburgh. The first scenario is that Neandertals occasionally interbred with modern humans after they migrated out of Africa. The alternative scenario is that the humans who left Africa evolved from the same ancestral subpopulation that had previously given rise to the Neandertals.

Did Europeans Get Fat From Neandertals?

Fathead? Modern humans (right) in Europe may have inherited genes from Neandertals that process fat in their brains and bodies.

Neandertals and modern Europeans had something in common: They were fatheads of the same ilk. A new genetic analysis reveals that our brawny cousins had a number of distinct genes involved in the buildup of certain types of fat in their brains and other tissues—a trait shared by today’s Europeans, but not Asians. Because two-thirds of our brains are built of fatty acids, or lipids, the differences in fat composition between Europeans and Asians might have functional consequences, perhaps in helping them adapt to colder climates or causing metabolic diseases.
“This is the first time we have seen differences in lipid concentrations between populations,” says evolutionary biologist Philipp Khaitovich of the CAS-MPG Partner Institute for Computational Biology in Shanghai, China, and the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, lead author of the new study. “How our brains are built differently of lipids might be due to Neandertal DNA.”

Pillage d’une nécropole antique à Prunay-Belleville


Depuis mi-février, les archéologues de l’Inrap interviennent à Prunay-Belleville, dans l’Aube, avant l’aménagement du gazoduc « Arc de Dierrey », réalisé sous la maîtrise d'ouvrage de GRT Gaz. Cette fouille, prescrite par l’État (Drac Champagne-Ardenne), vient de révéler trois ensembles funéraires majeurs : deux enclos de l’âge du Fer ainsi qu’un ensemble de sept sépultures antiques. Ces dernières, datées des IIe-IIIe siècles, très riche en mobilier funéraire, étaient particulièrement bien conservées. 
Mardi 4 mars, l’équipe de l’Inrap a constaté le pillage d’une partie des tombes gallo-romaines. Sur les lieux, la gendarmerie de Villenauxe-Grande a démarré une enquête. Une plainte a été déposée par l’Inrap.

Findings push back earliest known East-West interaction along Silk Road by 2,000 years
Charred grains of barley, millet and wheat deposited nearly 5,000 years ago at campsites in the high plains of Kazakhstan show that nomadic sheepherders played a surprisingly important role in the early spread of domesticated crops throughout a mountainous east-west corridor along the historic Silk Road, suggests new research from Washington University in St. Louis.
“Our findings indicate that ancient nomadic pastoralists were key players in an east-west network that linked innovations and commodities between present-day China and southwest Asia,” said study co-author Michael Frachetti, PhD, an associate professor of archaeology in Arts & Sciences at Washington University and principal investigator on the research project.

More on Neanderthals’ Genetic Legacy


SHANGHAI, CHINA—Neanderthals and modern humans are thought to have interbred at least once—probably in the Middle East—after modern humans left Africa. As a result, today’s Europeans and Asians carry a small amount of Neanderthal DNA. A new analysis of some of those Neanderthal gene variants, and an examination of brain tissues, suggests that today’s Europeans have three times as many Neanderthal genes involved in the breakdown of fats than Asians have. “This is the first time we have seen differences in lipid concentrations between populations. How our brains are built differently of lipids might be due to Neanderthal DNA,” evolutionary biologist Philipp Khaitovich of the CAS-MPG Partner Institute and the Max Planck Institute for Evolutionary Anthropology toldScience Now. Khaitovich thinks the fatty acid genes may have helped Neanderthals and Europeans adapt to living in the Northern Europe’s colder climates.

'Homo' is the only primate whose tooth size decreases as its brain size increases


Andalusian researchers, led by the University of Granada, have discovered a curious characteristic of the members of the human lineage, classed as the genus Homo: they are the only primates where, throughout their 2.5-million year history, the size of their teeth has decreased in tandem with the increase in their brain size.

The key to this phenomenon, which scientists call "evolutionary paradox," could be in how Homo's diet has evolved. Digestion starts first in the mouth and, so, teeth are essential in breaking food down into smaller pieces. Therefore, the normal scenario would be that, if the brain grows in size, and, hence, the body's metabolic needs, so should teeth.

PHOENICIAN COLONY IN SOUTHEAST SPAIN RE-EXAMINED

Cabezo Pequeño del Estany. Image: University of Alicante

Researchers in Spain have applied new remote sensing and aerial imaging to the Phoenician colony of Cabezo Pequeño del Estany of Guardamar under the project “Cultural Transfers in the Ancient Mediterranean” to begin a new round of archaeological works on the site.
The settlement was first discovered by chance in the late 1980s when it was partially destroyed by an illegal cement quarry and subsequently excavated in several seasons of rescue archaeology under the direction of Antonio García Menárguez, director of the Archaeological Museum of Guardamar.
