There have been speculations and theories that the Neanderthals didn’t actually go extinct, but rather that they mixed with the Homo-sapiens throughout Europe. Hence, Neanderthal DNA can still be found today, present in the modern humans.
It would appear that scientists have now discovered that a Melanesian tribe carries traces of human DNA that haven’t be found anywhere else before.
This means that there may have been or there may still be a new species of human that we haven’t encountered before. How weird is that?
