First look at an ancient genome from Neolithic Anatolia
Felix at GGT is in the process of uploading the genomes from the recent Pinhasi et al. paper. The file for the early Neolithic sample from Barcin, Turkey, is basically ready. I analyzed it with my K8 model and got these results (click on the image to enlarge).
I was only able to use a couple hundred SNPs for the test, so the outcome can't be taken too seriously. But it does make sense. The lack of Ancient North Eurasian (ANE) ancestry isn't surprising, because it mirrors the results of early European farmers we've seen to date.
Moreover, the relatively high level of Western European Hunter-Gatherer (WHG) ancestry, or at least something very similar, is also in line with expectations, considering that the sample was dug up in far western Anatolia, almost on the European border.
I also ran an Identical-by-State (IBS) affinity test using the Human Origins dataset and around 1800 SNPs. The results broadly back up the K8 analysis, with southern Europeans topping the list.
