Fully Steppe-like Proto-Corded Ware Late Trypillians

The genotypes from Human auditory ossicles as an alternative optimal source of ancient DNA, by Sirak et al. Genome Res. (2020), have been finally published by the Reich Lab, so we can get a sneak peek into what’s coming in future papers about the origins of R1a-rich Proto-Corded Ware and R1b-rich Italo-Venetic peoples.

NOTE. To avoid adding potential errors, I have merged the Reich Lab’s Curated Dataset (v. 42.4, March 1 2020) with these new samples before performing the qpAdm analyses. If you find something different with your files, you should probably check out this simple setting first. … Read the rest “Fully Steppe-like Proto-Corded Ware Late Trypillians”

Mitogenomes show likely origin of elevated steppe ancestry in neighbouring Corded Ware groups

Open Access Mitochondrial genomes reveal an east to west cline of steppe ancestry in Corded Ware populations, by Juras et al., Scientific Reports (2018) 8:11603.

Interesting excerpts (emphasis mine, references have been deleted for clarity):

Ancient DNA was extracted from the Corded Ware culture individuals excavated in southeastern Poland (N = 12) and Moravia (N = 3). Late Eneolithic (N = 5) and Bronze Age human remains (N = 25) originated from western Ukraine and came from the Yampil barrow cemetery complex located in the north–western region of the Black Sea. Bronze Age individuals were associated with different archaeological

Sredni Stog, Proto-Corded Ware, and their “steppe admixture”

Once the haplogroups of the announced West Yamna and Yamna settlers in Hungary and Khvalynsk from Ekaterinovka appear, it is to be expected that there won’t be much discussion on the Y-DNA bottlenecks that affected Khvalynsk – Yamna migrations.

So let’s cut to the chase and see where Corded Ware peoples (mainly of R1a-Z645 subclades) got their so-called “steppe admixture” different from that of Yamna. Because, as you might have realized by now, Sredni Stog – and consequently Corded Ware – remains nowadays an undefined (archaeological) mess.

Rassamakin explains it quite well, in the chapter Eneolithic of the Black … Read the rest “Sredni Stog, Proto-Corded Ware, and their “steppe admixture””
