    Where did K1 split from K2?

    And what would that suggest about the autosomal affinities of each?

    I suspect East Asia, possibly in a population with a similar autosomal profile to remains at Ust-Ishim (a 45,000 year old sample which carried Haplogroup K2a). However, we will never know for sure without Ancient DNA.

    Sounds plausible. I wonder if K2a was an Early East Eurasian line like K2b was. K1 the same?

    Respectively, Oase is in Western Eurasia (Romania), and Ust-Ishim is in Central Asia (modern-day Omsk Oblast, Russia). Keep in mind that Tianyuan is the only Paleolithic sample from East Asia, so it is still perfectly possible for K2a to have been in Eastern Eurasia. Keep in mind that K-Y28299, a highly divergent subclade of K2a, has only been found in South Asia, so that could possibly be informative as to the origins of K2a.

    I am agnostic on K1. Not much to say at this point, although it went through a 16,000 year bottleneck which probably ended somewhere in Western Eurasia.
