OK, so all you're saying is that once H. Sapiens had emerged as a
seperate species, there was no further exchange of genes with H.
Erectus. I can see where that would be the case. I don't know whether
we have enough evidence to conclude whether the isolation was behavioral
or due to genetic incompatibility, though. Perhaps eventually we'll be
able to at least make an educated guess.
