Basal Eurasian discussion

[TanTin]

I don't think there was a hub like that, that's really just for trying to make the Basal theory work. I read some of the supplements of that hard sweeps paper and I'm not convinced by their methods. I think it was rapid expansion in all direction with two main groups being the most successful. For the East population it definetely could have been a hub, suitable climate, large carrying capacity. A split somewhere in Iran after crossing Arabia and the strait of Hormuz. One group goes west and climbs to mountains, another reaches India. From there Ust'-Ishim can go north along the Himalayas.

To illustrate my idea, here's a (modern) climate map, green=good, red=bad. The green region is also where the lower Neanderthal East Eurasians are found, Longlin, Hoabinhian, Jomon, possibly AASI. As you venture north or south, you also get more archaic admixture.

"Basal" is not a Theory and not a geographic location.
"Basal"  is a huge component and we register such components in all humans, including in Africans.
However this is in my definition for "Basal".  And I think this was the initial idea of Lazaridis when he introduced this term. 

Basal Eurasian is a proposed lineage of anatomically modern humans with reduced, or zero, archaic hominin (Neanderthal) admixture compared to other ancient non-Africans.

The definition given by Lazaridis doesn't work also, because there are many kind of "archaic".
So the Basal could be low on Archaic Neanderthal, but they could be rich on other type of "archaic" hominin.
