Re: Or, Africa was uninhabitable for long while and was the last area to be repopulated after the glaciation.
As far as I know, there was almost no glaciation at all on the African continent during the last ice age.
However, 20,000 years ago, there is evidence of extreme drought in northern Africa and the Arabian peninsula and in southwest Africa during the last glacial maximum.
Al lthis just shows women will sleep with anyone.
Something we tend to do is not look back far enough. There were three ice ages and four interglacials in the last 350,000 yrs. It happens in a regular cycle approximately every 125k, so since the earliest known Homo erectus find dated to 1.8 million years ago there have been 14 glacial/interglacial periods where migration could have been necessary for survival of hominids.
Each of these could have been associated with migrations north/south again as these cycles came about, and each would have resulted in it’s own post migration evolution depending on location and environment. There were ice ages before the last ice age and we limit our scope of perspective to only the last ice age and it is a mistake, we need to look at the longer time line and consider there were actually 14 of these cycles.
Yup, dryer than now.

And, the glaciation of Africa during the Holocene hasn’t been studied, primarily because it puts the hurt to the “Out of Africa” replacement master-race nonsense.
