Uhh, horses and donkeys produce mules but cousins produce fertile cousins.
Although H. sapiens breeding with H. erectus, might be a little like horses and donkeys breeding. And H. sapiens with Neanderthals, even more so. Of course, we'll never know.

I'm not so sure about that. I see some pretty suspect couples walking around Wal-Mart in my bi-weekly visits. :shock:
Hmmmm, I know scientists say that Homo Sapiens didn't breed with Erectus and Neanderthalis, and the DNA evidence appears to bear them out, but I'm pretty sure Sapiens got jiggy with the locals when they first moved in! I have it in my head that being cousins, any intercourse would be like horses and donkeys, producing mules.
Fascinating topic - thanks all. A minor correction, Ian. That would only be intercourse where the participants were not practicing safe sex... :wink:
You're getting confused, rasb. Trojans came later, just before the Greeks ...
Do you know of a similar illustration of the relationship between 60,000 year old humans and the much older "humanoid" fossil evidence also found in East Africa?
I just found an article that touches on some of the older African migrations and genetics.
Daisy. Re your earlier posting from the human diversity project. Some lines (e.g. D and C) appear to be have been great sailors! I can imagine getting across from the Indonesian area to Australia, but some of the others (e.g. C3 and D) look fishy, and need to be fleshed out by "spotting" descendants of the wayfarers enroute.
I have tended to be a little skeptical about many details since the early 1980s. What happened to the idea of an Eve like figure in East Africa some 200,000 years ago? Now there is talk of an Adam like figure somewhere in the Kazakhstan area, for much of the current population (though not Africans or Indians). The actual timing details also need to be nailed down much better - no expert, but these look questionable. (I know nothing of "dating" in the biological sciences, but know of enough bad ages and dates in what is supposed to be a much more robust field - earth sciences).
Catson, it all depends which genetic markers you follow. In this case those that originate from Y. For eve they use mitochondrial ones. You get different migration narratives and founders depending on which set you follow. The adam figure actually postdates eve by tens of thousands of years.
The reason for this discrepancy is that the Y chromosome diversity was eroded by genetic drift. A couple of reason might explain this, women travelled as brides further a field and the genetic diversity in the mitochondria was quite high, whereas the men often stay local, so some new mutations would just be lost by random luck. This could happen if one dominant father has children from many different woman leading to other Y's in the community getting lost. The consequence of this genetic drift is that the Y common ancestor is actually more recent.
As to the sea faring for the genetic signals to be where they are they must have been great sailors. C3 is actually done by coastal hops. The amazing sea faring events are the ones to australia C and the pacific islands M.
