>>2573598>Yamnaya are the current oldest Indo-Euro culture knownNo my MENA friend :) We have older R1a and R1b samples from Samara, Khvalynsk, Dniepr-Donets. Dniepr-Donets people were also R1a just like Nordid Corded-Wareans :)

Andronovians were Nordid, except one guy with dark brown hair who was a C y-DNA Mongoloid slave.
