The story of the evolution of modern humans can be a bit confusing, species-wise, with many early hominins co-existing without an obvious linear succession. But, geographically, all the action has appeared to take place in Africa, at least until the appearance of Homo erectus, which left Africa and spread globally, only to be replaced by later species of African origin: us. Over the past year or so, however, our history has become a bit more complicated, with evidence that our ancestors interbredwith earlier human relatives that had already dispersed throughout Asia. Now, earlier events are also looking a bit more confused, as archeological finds in the nation of Georgia are being promoted as evidence that Homo erectus didn’t even get its start in Africa.
