Ancient DNA from Peştera cu Oase, Romania

The authors analyzed DNA from a 37,000-42,000-year-old modern human from Peştera cu Oase, Romania. They found that on the order of six to nine percent of the genome of the Oase individual is derived from Neanderthals, more than any other modern human sequenced to date. Three chromosomal segments of Neanderthal ancestry are over 50 cM in size, indicating that this individual had a Neanderthal ancestor as recently as four to six generations back. The Oase individual does not share more alleles with later Europeans than with East Asians, suggesting that the Oase population did not contribute substantially to later humans in Europe. I converted the raw data of these samples into formats familiar to genetic genealogists. The complete SNPs are available for download. However, there is not much common SNPs when filtered with SNPs tested by DNA testing companies like FTDNA, 23andMe and Ancestry, hence not uploaded to GEDmatch. Haplogroups, site location, and age of the sample etc as per the authors can be found in Ancient DNA page.
