K = 14 admixture analysis of Neolithic Estonian genomes

Below is a plot for a K = 14 admixture analysis that includes seven genomes from Neolithic Estonia. The table above the plot gives some information for these samples.

The hunter-gatherer samples from the Comb Ware culture are similar to the Comb Ware sample from Latvia, the earlier hunter-gatherer samples from Karelia and Samara in Russia, and the earlier Mesolithic and Dnieper-Donets samples from Ukraine. All of these samples are made up mostly of the medium blue Eastern component, but also have significant amounts of the dark blue Western component. The Baltic Comb Ware samples have more of the Western component than the Russian samples, but less than the Ukrainian samples.

The Estonian Corded Ware samples are indistinguishable from the other Corded Ware samples from Germany and Poland. They differ from the Corded Ware sample from Latvia, which lacks the light blue early farmer component.

Sample       Culture      Date BC
Kudruküla 2  Comb Ware    3831–3426
Kudruküla 3  Comb Ware    3950–1850
Ardu 1       Corded Ware  2850–2050
Ardu 2       Corded Ware  2921–2555
Kunila 1     Corded Ware  2850–2050
Kunila 2     Corded Ware  2626–2390
Sope         Corded Ware  2625–2400
