The West Kennet long barrow served as a tomb and ceremonial site for more than a millennium. Thirty kilometres north of Stonehenge, through the rolling countryside of southwest England, stands a less-famous window into Neolithic Britain. Established around bc by early farming communities, the West Kennet long barrow is an earthen mound with five chambers, adorned with giant stone slabs. At first, it served as a tomb for some three dozen men, women and children. But people continued to visit for more than 1, years, filling the chambers with relics such as pottery and beads that have been interpreted as tributes to ancestors or gods. The artefacts offer a view of those visitors and their relationship with the wider world. Changes in pottery styles there sometimes echoed distant trends in continental Europe, such as the appearance of bell-shaped beakers — a connection that signals the arrival of new ideas and people in Britain. But many archaeologists think these material shifts meshed into a generally stable culture that continued to follow its traditions for centuries. But last year, reports started circulating that seemed to challenge this picture of stability. A study 1 analysing genome-wide data from ancient Europeans, including associated with Bell Beaker-style artefacts, suggested that the people who had built the barrow and buried their dead there had all but vanished by bc.

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. European hunter-gatherers fall beyond present-day Europeans in the direction of European differentiation from the Near East. Stuttgart clusters with other Neolithic Europeans and present-day Sardinians.
MA1 falls outside the variation of present-day West Eurasians in the direction of southern-northern differentiation along dimension 2. We estimate nuclear contamination rates to be 0.

DNA test kits like AncestryDNA and 23andMe have become increasingly popular over the past few years — some 26 million people have taken them — and were a big gift item during the holiday season. The possibilities are quite literally endless — from finding your birth mother after 47 years to discovering that you’re related to a president.
Though DNA tests are being added to more and more people’s bucket lists, the sheer number of kits you can choose from is overwhelming. The result? A lot of interested folks opt out simply because they’re not sure which kit to buy. Even DNA tests for your dog exist.

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.
These Bronze Age population replacements are associated with the Beaker culture archaeologically and with the Indo-European expansion linguistically. Ethnogenesis of the modern ethnic groups of Europe in the historical period is associated with numerous admixture events, primarily those associated with the Roman , Germanic , Norse , Slavic , Arab and Turkish expansions.
Research into the genetic history of Europe became possible in the second half of the 20th century, but did not yield results with high resolution before the s. In the s, preliminary results became possible, but they remained mostly limited to studies of mitochondrial and Y-chromosomal lineages. Autosomal DNA became more easily accessible in the s, and since the mids, results of previously unattainable resolution, many of them based on full-genome analysis of ancient DNA, have been published at an accelerated pace.

In , archaeologists excavating the Viking town of Birka, Sweden, uncovered a singular ornate 10th-century burial tomb believed to hold the remains of a great warrior. The site was filled with a trove of weapons, including a sword, spear, shield and two horses, as well as a game board likely used to map out military strategies. Further emphasizing its noteworthiness, out of 1, Birka tombs identified on the settlement, it was just one of two that contained a full set of weaponry.
Guided by comprehensive genomic sequencing, archaeologists first revealed the unexpected findings of the woman warrior in a study published in the American Journal of Physical Anthropology. Now, the authors of the original paper have released a follow-up study, newly published in Antiquity , reaffirming their original conclusions and delving deeper into the secrets of the grave.
The latest batch of research addresses many of the concerns raised by critics; at the same time, Little notes, the paper acknowledges the difficulty of assessing gender roles and identity in such a long-ago culture. Domestic tools one might more closely associate with Viking women are, on the other hand, absent from the grave. Finally, as Geggel observes for Live Science , the location of the tomb at the westernmost reaches of Birka suggests it was visible from both the sea and the town.
Marked by a large stone boulder, the site would have been known to all as the grave of a likely high-ranking member of the community.

L ast year, I did what 12 million people from all over the world have done and surrendered my spit to a home DNA-testing company. I hoped a MyHeritage test would bring me the peace I needed; my Irish mother had never been able to give me any information about my biological father. But, at 24, I was done with occupying a box of black ambiguity. Could I finally get a clear answer? I had no cultural knowledge of Nigeria; should I now start claiming it as my own?
Did the results mean my very distant ancestors were Nigerian, or that my biological father was probably from there?

Dna Egypt. This is a developing story. Because of the dry Egyptian climate, however, there are also many natural mummies preserved from earlier as well as later times. Rather this number includes the years that the Israelites’ ancestors sojourned in other foreign lands, and also includes the thirty years between the Covenant Between the Parts and Isaac’s birth. For example, a 2,year-old cat in Egypt had DNA.
The Philistines and Sea Peoples. It likely has even more ancient roots; four of the Egyptian mummies carried the parasite’s DNA, each dating from the Middle Kingdom period of to B. The birds went extinct in Egypt by the midth century, likely due to. Ancient Egyptians were from upper Egypt. Ancient DNA can provide us with a broader picture of the interactions that led to modern populations: a precious snapshot delivered directly by Egyptian mummies.
