Last month the story was that Neanderthals and ancient humans interbred in southern Europe hundreds of thousands of years earlier than previously thought, totally upending the out-of-Africa theory which had held that one small band left Africa around 100,000 years ago and became the basis for all of us today. Now people must talk of more than one out-of-Africa migration. And apparently, too, it wasn’t just Neanderthals that mingled with ancient hominids – Denisovians did too, and maybe others as well. NOW comes evidence that modern humans reached Australian over 65,000 years ago, 18,000 years earlier than previously thought. This means they sailed across the open sea in boats, out of sight of land, enough of them to start a community and then a continent-wide occupation. Could it be that the tectonic plates of human origins are cracking, and shifting? Is the out-of-Africa theory under siege? A theory, once accepted, is defended like death. But true science sometimes shatters theories. Must shatter theories.
I am waiting, eagerly, for the first documented find of ancient humans, people who lived more than 50,000 years ago, somewhere on North or South America. Just because no evidence has yet been found (that has been verified) does not mean no evidence exists.
