I'm still on the fence about the multiregional hypothesis. It's abundantly clear to me that hominin lineages were not cleanly divided into discreet units, and that our species is not descended from a single tribe of intrepid explorers coming out of Africa. However, I still feel like there's a whole lot of overinterpretation going on.
In my mind, the Multiregional hypothesis would have predicted a much higher rate of introgression than is being detected. All detected mixing has so far been attributable to very small numbers of events, so it seems clear to me that the major pattern in human evolution has been divergence among regional populations/species, rather than admixture.

Re: definition?
Hi, Coyote.
I have to say, even as a skeptic of multiregionalism, there is a lot more admixture than I would have expected. And the earlier dates in this new study do show a lot more complexity to the history of human evolution. It's certainly a wide-open question as to how much intermixing there actually was.
Just how far do we think this evidence can go? For example, is it possible that modern Asians are best explained as surviving Homo erectus, with some Homo sapiens admixture?
