African phylogeny (beginning...)

[Chad Rohlfsen]

Here is a little image here for everyone to browse. This fits well and is in agreement for D-stats. There are several African components. The oldest is a "basal human" lineage that is labeled W_Africa which maximizes in the Shum_Laka individuals here. South_Africa_2000BP maximizes S_Africa at 100%. No additional ancestry is needed here. East Africa is featuring two splits. One that maximizes in Kenya_LSA and Shum_Laka, while the other is maximized in Mota. In this, Mota splits off before OoA, which is shared more with Kenya and Shum_Laka. There is no affinity to the crown Eurasian groups exemplified by SunghirIV, Ust_Ishim, and Tianyuan. I think this is a cue that these individuals are unadmixed with post-OoA groups. Although, adding more individuals may change that. I'll add some more Africans to this, before expanding onto more recent Eurasians.

Great news! I've gotten even further with Africa. I definitely need a population that has more basal human than Shum Laka. They have additional East African ancestry.

The earlier population is wild looking. I'll have that hopefully before the end of the night.

Back-to-Africa flow to IBM is also not at all what we would expect. This is absolutely nuts.

Would love to see where Dinka/Nilotes would find themselves as opposed to the ancestors of HoAs as they seem very different at this point. Also the split in West Africa [Senegambian] versus West Africa Bantu [Lemande] and how intermediate populations i.e. Nigerians formed.

Please elaborate.

I am interesting in seeing if your analysis generates common ancestry among NS and NK(especially Senegambians) and a more composite nature of seemingly Homogenous Nilotes.

This is pretty wild. That's all I'll say for now. I'm not sure if this is going to be one giant post, or if I'll split posts on West and East Eurasians. That whole replacement on Y chromosomes was on point.

I've found Basal Eurasian!!!!!!!!!!!!!! Hoooooly Shit! Sorry for the language, but I can't believe how easy that was.

[Chad Rohlfsen]

Wow... I can model anything now!

[Chad Rohlfsen]

I really think this is going to hold. I can do the whole population history of the world.

I can see OoA now too!!! Wow!
