>>12939260Idk, the evidence seems ti support it as far as I know. Oldest hominid skeletons and hominid species existed there, so we definitely spent a lot of time there evolving and diverting.
A way to falsify it is to find older human skeleton outside of Africa, and as far as I know, this has not been attempted yet.
In fact, iirc, the oldest human skeleton with modern European DNA was found in southern Italy and is like 28K years old.
