Homo erectus was introduced into our gay friendly neighborhood as a means toward gentrification... Oh, wait... (nevermind). As for the tools, they say that only a poor craftsman blames his tools. The rest of us still hack away with our stone axes as a point of honor...

But there couldn't have been a single individual like Eve (or Lilith) if, on the basis of mitochondrial DNA polymorphisms, geneticists are right to *EXCLUDE * the theory that a constriction down to one or few women occurred in Africa at the transition from archaic to anatomically modern humans, some 200,000 years ago.

I'm sorry, I mis-wrote. What these particular geneticists said was that "...the MHC polymorphisms exclude the theory..." (posed by the mitochondrial genetists). This newer finding would also more strongly argue against the Creationist interpretation. (whew!)
