Today we rewrite human history

BBC News reports that according to skulls recently discovered in Kenya, Homo erectus and Homo habilis lived simultaneously in East Africa for around a million years. This is somewhat problematic for the commonly held belief that the former evolved from the latter, although nothing can obviously be said for sure.

Meanwhile in Europe, it seems that much of the European population of humans did not necessarily come directly out of Africa, as is commonly suggested. A study of fossil teeth indicates that the second migration wave out of Africa, which was supposed to take place between a million and half a million years ago, possibly didn’t happen in similar numbers as did the first (1.5 million years ago) and the third (50 to 30 thousand years ago, and involving modern humans).
