The Genetic Origin of the Indo-Europeans

[Kale]

It is unfortunate we have no samples from Western Kazakhstan prior to the bronze age to help elucidate the 'Tutkaul' component of CLV.
I suspected it for a while but thought I was in a small crowd in that respect.
Anyways, here's some models for Kumsay_EBA and Steppe Maykop.

I wonder if this surplus Tutkaul is from the same source that contributed to CLV in the first place?
