what natural barriers separated hominids in parts of africa, or middle east / northern africa? As Erectus and later heidelbergensis was i belive from what ive read widely populated trough Africa, Asia and the southern parts of Europe, to the point where it split into many “regional subspecies”?
Sapiens, Neanderthal and Denisovans could interbreed, could Erectus with heidelbergensis?
https://www.latimes.com/science/story/2019-07-10/oldest-modern-human-skull-in-eurasia Is this valid? for the future how can i determine if stuff like this is valid?
Also if someone could if possible just do a brief summery on how to best classify our relation with Denisovans and Neanderthals?
How i roughly picture it in my head: Erectus->Heidelbergensis got seperated into areas and splitting of into Africa(homo sapiens) Southern and central Europe and parts of Asia/middle east(Neanderthals) And Asia(denisovans) With the last 2 being more closely related than with H.sapiens? This is obviously meant as a rough simplification, i know its much more complicated than this.
But then again with the link to the 200k old sapien skull in Greece, along with the fact that we are finding Neanderthal genes in Africans, so there has to been more waves of migration out and in of Africa than previously belived?
