Show me WHERE the OOA is dated. It seems you're blowing a bunch of nonsense out of nowhere. And who the heck was even talking a replacement theory????
Watch the video again because nowhere is he saying the stuff you are saying. What he is really saying is that Archair humans like Neanderthals were STILL around during the OOA and that there was still interbreeding and the Archair human DNA did not vanish. I'm actually well versed on Chris Stringers work and here's a link on his "
Rethinking Out of Africa".
The Homo Sapien group that moved out of Africa interbred with the Neanderthals, and later on with Denisovans. Meaning Denisovans were still around during the OOA.
Or its due to the multiple Homo Sapien OOA streams later mixing Denisovans admixture with Neanderthals Homo Sapien. Since the Neanderthals not Denisovans distribution hasn't been spread equally (Europe-Asia).
(1-4%) contribution to the gene pools
I interpret this as multiple intrusions/ OOA of Homo Sapiens coming into Asia and Europe, bringing in a variety of this gene distribution (in later arrivals).
Chris states:
To me this means Homo Sapiens were evolving faster than other
"species", And this is perhaps also in the ancestral loop. Where we split off from the Neanderthals, Denisovans and other "species".
Chris states:
Again does not agree with what you were saying. But more importantly tells us my fossils in this part of the world is lacking until recent times...
Chris states"
Shows why very early Homo Sapien distribution is found in East and South Africa.
They haven't found any remains in Central and West Africa as of yet, due to the large field coverage. So this picture is not clear.
Chris also states:
Maybe any of these are ancestral to Homo Sapiens? Who died out earlier, just like the Neanderthals and Denisovans died out. But leaving a large genetic stem on Modern Humans, or were perhaps the proto-Homo Sapiens????
Chris states:
To test the robustness of the backbone and the root of current Y chromosome phylogeny, we searched for SNPs that might be informative in this respect. To this aim, a resequencing analysis of a 205.9 kb MSY portion (183.5 kb in the X-degenerate and 22.4 kb in the X-transposed region) was performed for each of seven chromosomes that are representative of clade A (four chromosomes belonging to haplogroups A1a, A1b, A2, and A3), clade B, and clade CT (two chromosomes belonging to haplogroups C and R) (Table S1 available online).

Chris even states:
Homo Heidelbergensis. which is the oldest of the bunch. The one that originated in Africa.

Chris also states:
All in all Chris Stringer does not agree with your claims that the Out of Africa is dated and should be replaced with the multiregional theory.
The multiregional theory is hardly taken serious in academia. Multi-Regional theory that modern man evolved in different Regions of the world is not supported by genetics or even microbiology.Out Of Africa is supported by genetics and microbiology.I read that a bacteria called "Heliocobacter Pylori" which is part of our stomach flora has
been traced BACK TO AFRICA based on it's own phylogeny.
OOA dated? Dated my ass.
