Some new Neolithic Anatolians

Well, thanks to a new study, we now have some new Neolithic Anatolian samples. This time they're from South-Central Anatolia and date to between 8300 and 5800 BCE.




Seems the Boncuklu samples (~8300-7500 BCE) are nearly identical to the Barcın (Northwestern) Neolithic Anatolians in terms of WHG/Villabruna-related ancestry and "ENF-like/Basal-rich"-related ancestry whilst the Tepcek samples (~7500-5800 BCE) are less Villabruna-shifted and thus pull a bit more toward Neolithic Levantines and Natufians. You can see this in David's PCA (Principal Component Analysis based on autosomal SNPs) below:



The more left a population pulls; the greater the affinity for Villabruna-type Hunter-Gatherers whilst the more right the pull indicates how ENF-like/Basal-rich they are. Finally, the more north a population pulls indicates how "ANE" shifted they are. Neolithic Anatolians, Neolithic Levantines and Natufians pull the absolute least toward the north as they seem to lack ANE-related admixture.

Notes:

1. The mtDNA diversity among these samples is rather interesting to me as someone from the Horn of Africa, to be honest. N1a1a1, N1b, K1a, K1a12a, U3: these are quite close to or directly overlap with the mtDNA Haplogroups you can find among Somalis and other Horn African populations.
