I have updated the Ancient DNA Dataset, including a lot of new information from – among other sources – the latest version of Reich Lab curated Dataset, now renamed Allen Ancient DNA Resource (AADR). This includes new columns:
- Object-ID: I am now using whenever possible the Master-ID; Version-ID for a quick identification of the ‘best’ sample to include in SmartPCA or ADMIXTURE runs; and Index as a key with a unique reference number for each sample. That should make for enough stable references for any external tool to use the data.
- mtDNA: Added mtDNA coverage

New papers Genomic History of Neolithic to Bronze Age Anatolia, Northern Levant, and Southern Caucasus, by Skourtanioti et al., and (open access) The Genomic History of the Bronze Age Southern Levant, by Agranat-Tamir et al., both in Cell (2020) 181(5).
Interesting excerpts from Skourtanioti et al. (2020) (emphasis mine):
Genetic Continuity in Anatolia
We focused on the three Late Chalcolithic groups with sufficiently large sample size and who are the earliest in time among the LC-LBA groups: ÇamlıbelTarlası_LC (n = 9), İkiztepe_LC (n = 11), and Arslantepe_LC (n = 17). Taking individual estimates from all these individuals together

The recent update on the Indo-Anatolian homeland in the Middle Volga region and its evolution as the Indo-Tocharian homeland in the Don–Volga area as described in Anthony (2019) has, at last, a strong scientific foundation, as it relies on previous linguistic and archaeological theories, now coupled with ancient phylogeography and genomic ancestry.
There are still some inconsistencies in the interpretation of the so-called “Steppe ancestry”, though, despite the one and a half years that have passed since we first had access to the closest Pontic–Caspian steppe source populations. Even my post “Steppe ancestry” step by step from a year ago … Read the rest ““Steppe ancestry” step by step (2019): Mesolithic to Early Bronze Age Eurasia”
