The Neolithic lifestyle, including farming, animal domestication and the development of new technologies, emerged in the Near East around 12, years ago and contributed profoundly to the modern way of life. The Neolithic spread rapidly across Europe, mainly along the Danube valley and the Mediterranean coastline, reaching the Atlantic coast around BCE. The existing archaeogenetic data from prehistoric European farmers indicates that the spread of farming is due to expanding populations of early farmers who mixed little, if at all, with indigenous hunter-gatherer groups. However, until now, no archaeogenetic data were available for France. These interactions seem to vary greatly from one region to another, attesting to a diverse cultural mosaic in early Neolithic Western Europe. The study, published in Science Advances , reports new genome-wide data for prehistoric individuals from 12 archaeological sites in today’s France and Germany, dating from BCE.

A team of international researchers, which includes a Saint Louis University Madrid anthropologist, dug deep to find some of the oldest African DNA on record, in a new study published in Nature. Africa is the homeland of our species and harbors greater human genetic diversity than any other part of the planet. Studies of ancient DNA from African archaeological sites can shed important light on the deep origins of humankind. The research team sequenced DNA from four children buried 8, and 3, years ago at Shum Laka in Cameroon, a site excavated by a Belgian and Cameroonian team 30 years ago.
The findings, “Ancient West African foragers in the context of African population history,” published Jan. They enable a new understanding of the deep ancestral relationships among early Homo sapiens in sub-Saharan Africa. Shum Laka is a rock shelter located in the ‘Grassfields’ region of Cameroon, a place long pinpointed by linguists as the probable cradle of Bantu languages, a widespread and diverse group of languages spoken by more than a third of Africans today. This expansion is thought to be the reason why most people from central, eastern and southern Africa are genetically closely related to each other and to West Africans.
The Shum Laka rockshelter was excavated in the s and s by archaeologists from Belgium and Cameroon. It boasts an impressive and well-dated archaeological record, with radiocarbon dates spanning the past 30, years. Stone tools, plant and animal remains, and eventually pottery collectively indicate long-term forest-based hunting and gathering and an eventual transition to intensive tree fruit exploitation.
Shum Laka is emblematic of the ‘Stone to Metal Age,’ a critical era in west-central African history that ultimately gave rise to Iron Age metallurgy and farming. During this era, the site repeatedly served as a burial ground for families, with 18 individuals mainly children buried in two major phases at about 8, and 3, years ago.
24,000-Year-Old Body Shows Kinship to Europeans and American Indians
A research team co-led by a scientist at New Zealand’s University of Otago has sequenced the first complete mitochondrial genome of a year-old Phoenician dubbed the “Young Man of Byrsa” or “Ariche”. This is the first ancient DNA to be obtained from Phoenician remains and the team’s analysis shows that the man belonged to a rare European haplogroup—a genetic group with a common ancestor—that likely links his maternal ancestry to locations somewhere on the North Mediterranean coast, most probably on the Iberian Peninsula.
Study co-leader Professor Lisa Matisoo-Smith of the Department of Anatomy says the findings provide the earliest evidence of the European mitochondrial haplogroup U5b2cl in North Africa and date its arrival to at least the late sixth century BC. It is remarkably rare in modern populations today, found in Europe at levels of less than one per cent. Interestingly, our analysis showed that Ariche’s mitochondrial genetic make-up most closely matches that of the sequence of a particular modern day individual from Portugal,” Professor Matisoo-Smith says.
“The DNA evidence based on those bones completely upends the far from the Celt homelands in the middle of Europe at a very, very early date. “It just didn’t fit with the traditional theory of Celtic spreading west to Britain and Iberia.” and are a dangerous element in the body politic of a free country.
Cells, including fetal cells, tumor cells, or cells from transplanted organs, release DNA into the blood stream. This DNA can be analyzed using PCR or next-generation sequencing to understand genetic characteristics of a developing fetus, a cancer tumor, or a transplanted organ from a blood draw. Molecular diagnostic tests using ccfDNA enable clinicians to gain actionable biological insights without a tissue biopsy or similar invasive test.
The PAXgene Blood ccfDNA tube provides a solution for clinical laboratories to stabilize samples when the sample cannot be processed on the same day it was collected. Where standard EDTA tubes require processing within hours before cells die and release genomic DNA into blood plasma thus changing the native ccfDNA profile , the PAXgene tube has a unique stabilization chemistry that enables collection and processing to occur days apart, addressing a critical logistical hurdle for reference labs offering molecular testing outside of the hospital setting.

Introducing Our New DNA Ethnicity Analysis
The genetic history of Europe since the Upper Paleolithic is inseparable from that of wider Western Eurasia. By about 50, years ago 50 ka a basal West Eurasian lineage had emerged alongside a separate East Asian lineage out of the undifferentiated ” non-African ” lineage of 70 ka. European early modern humans EEMH lineages between 40 and 26 ka Aurignacian were still part of a large Western Eurasian “meta-population”, related to Central and Western Asian populations.
We know that our species originated in Africa and likely reached Europe from the southeast no later than 42, years ago. During the last ice age some 33,, years ago, when a permanent ice sheet covered northern and parts of central Europe, modern humans in southwest Europe were isolated from groups further to the east. When the ice sheet retreated, some of these hunter gatherers eventually colonised Scandinavia from the south about 11, years ago, making it one of the last areas of Europe to be inhabited.
But exactly who these individuals were and how they got there has remained a puzzle for researchers. Now we have sequenced the genomes of seven hunter gatherers, dated to be 9,, years old, to find out. One of the reasons the origins of the first Scandinavians is so enigmatic is a major shift in stone tool technology that appeared soon after they got there.
This new technology seemed to have had an origin in eastern Europe and it has been an open question how it reached Scandinavia. Our interdisciplinary research team combined genetic and archaeological data with reconstructions of the ice sheets to investigate the earliest people of the Scandinavian peninsula. We then compared the genomic data with the genetic variation of contemporary hunter gatherers from other parts of Europe. To our surprise, hunter gatherers from the Norwegian Atlantic coast were genetically more similar to contemporaneous populations from east of the Baltic Sea, while hunter gatherers from what is Sweden today were genetically more similar to those from central and western Europe.
One could say that — in Scandinavia at that time — the geographic west was the genetic east and vice versa.
Despite the increasing availability of direct-to-consumer DTC genetic testing, it is currently unclear how such services are regulated in Europe, due to the lack of EU or national legislation specifically addressing this issue. Emphasis is placed on provisions relating to medical supervision, genetic counselling and informed consent.
Our results indicate that currently there is a wide spectrum of laws regarding genetic testing in Europe.

Near Eastern migrants played a major role in the introduction of agriculture to Europe, as ancient DNA indicates that early European farmers were distinct from European hunter-gatherers 4 , 5 and close to present-day Near Easterners 4 , 6. However, modelling present-day Europeans as a mixture of these two ancestral populations 4 does not account for the fact that they are also admixed with a population related to Native Americans 7 , 8.
To clarify the prehistory of Europe, we sequenced nine ancient genomes Fig. We show all sampling locations for each population, which results in multiple points for some e.

DNA Analysis Suggests Ancient Rome Represented a Genetic Crossroads of Europe and the Mediterranean
Some defining features of their skulls include the large middle part of the face, angled cheek bones, and a huge nose for humidifying and warming cold, dry air. Their bodies were shorter and stockier than ours, another adaptation to living in cold environments. But their brains were just as large as ours and often larger – proportional to their brawnier bodies. Neanderthals made and used a diverse set of sophisticated tools, controlled fire, lived in shelters, made and wore clothing, were skilled hunters of large animals and also ate plant foods, and occasionally made symbolic or ornamental objects.

The first people to arrive in the Americas have long been assumed to have descended from Siberian populations related to East Asians. It now seems that they may be a mixture between the Western Europeans who had reached Siberia and an East Asian population. Elsewhere at the same site about 30 Venus figurines were found of the kind produced by the Upper Paleolithic cultures of Europe. The remains were excavated by Russian archaeologists over a year period ending in and stored in museums in St.
There they lay for some 50 years until they were examined by a team led by Eske Willerslev of the University of Copenhagen. Willerslev, an expert in analyzing ancient DNA, was seeking to understand the peopling of the Americas by searching for possible source populations in Siberia.

A personal genomics company in Switzerland says they’ve reconstructed a DNA profile of King Tutankhamen by watching the Discovery Channel, claiming the results suggest more than half of Western European men are related to the boy king. But researchers who worked to decode Tut’s genome in the first place say the claim is “unscientific. Swiss genomics company iGENEA has launched a Tutankhamen DNA project based on what they say are genetic markers that appeared on a computer screen during a Discovery Channel special on the famous pharaoh’s genetic lineage.
If the claims were true, it would put King Tut in a genetic profile group shared by more than half of Western European men. That would make those men relatives — albeit distant ones — of the pharaoh. The Y chromosome is the sex chromosome found only in males, and looking at the genes in this chromosome would show Tut’s male lineage.
But they didn’t publish the full genetic data that would allow genomics companies like iGENEA to link modern people to the Tutankhamen lineage. According to Scholz, that crucial data is what appeared on the Discovery Channel. The alleged Discovery Channel markers put Tut in a genetic profile group, or haplogroup, that also includes more than half of the men in Western Europe. Scholz said the company is now searching for the closest living relatives of Tutankhamen , men who share all 16 genetic markers on the pharaoh’s supposed Y chromosome.
