At approximately 200 kya there was a second migration of hominids out of Africa.
This time it was fully modern , which proceeded to replace whatever populations that then occupied Asia and Europe.
The general opinion among researchers seems to go in cycles, supporting Oo A, then supporting , then supporting Oo A, etc.
Currently, we seem to be at a cusp of support for replacement, and there seems top be a shifting in opinion more favorable to continuity.
This certainly holds true for Europe, where the perceived differences between the earlier Neanderthal populations and later “modern” H. There are many sites which are attributed to what are called “early modern humans” are not always particularly older than “fully” modern humans, nor later than Neanderthal sites.
For example, multiregionalism is often portrayed as a racist theory that claims different “races” have evolved to different “levels” of intelligence.And the limb proportion argument cannot be resolved without a migration of Africans either bodily or genetically.
