An online interview with Fred Spoor about the new finds at Koobi Fora. Here is a quote concerning how important the discoveries are:

If fact, Homo habilis and Homo erectus both come in at about the same time, in bout 1.9 million. And at about 1.4, Homo habilis disappears, Homo erectus continues then. But it means that they lived side-by-side for about, almost, half a million years and that must surely mean that they really had separate ecological niches to survive in this way for such long time. And then you can ask the question, is it likely that one was actually the ancestor of the other, because classically, Homo habilis has been portrayed as the ancestor of Homo erectus who either gradually or through a rapid speciation gave rise to erectus.

Time to rewrite that section of the class.
