A new study by the Uppsala University et. al. has pushed the emergence of modern humans back to at least 300 kya and possibly even to 350 kya. Funny how not so long ago we used to think our species emerged 100 kya, then 200 kya, and now 300-350 kya isn’t it? Frankly, I think even newer research will soon push our emergence back even further! You can read the whole story at the link below.
So consider this in perspective………. Homo erectus is believed to have went extinct around 143 kya so if modern humans emerged 300-350 kya then that means that these two species COEXISTED for at least 100-150 thousand years! And there was a time when H. erectus, modern humans, Heidelbergensis, and Neanderthals coexisted! And you don’t think all of these human species interbred? Think again LOL!!
Regarding Neanderthals two new studies have emerged. One suggests Neanderthal-Denisovans almost disappeared after separating from modern humans and that find challenges the conventional theory about all three species! Another study has revealed diet may be the blame for the Neanderthals demise in contrast to the diet of modern humans which enabled us to survive. Perhaps. I’m sure diet was important just as it is today but, again, I assert that the Neanderthals didn’t go extinct at all. They interbred with modern humans and produced viable offspring hybrids! In my mind what appears to have happened is (borrowing a line from Star Trek) modern humans came along and for all other species resistance was futile! These other species didn’t go extinct. We had sex with them and produced hybrid offspring capable of breeding and producing more hybrids! And that’s how we mods became the Mutt People we are today!!! Sorry…no pure races left and no pure human species left (if there was ever) and there hasn’t been for a long time. Want personal proof? Research your own ancestry and it will become as clear as day to you. 🙂
