[extropy-chat] Re: Hybrids

[Kevin Freels]

Given the number of people engaging in farm animal sex, let alone people who
appear "different" from themselves, I hardly see how humans could ever split
into different species unless there was absolutely no contact between two
groups for hundreds of thousands of years. There would also have to be
several changes in environment that kept the two isolated places changing in
different ways. Heck, Bonobos and Chimps are seperated by 3 million years.

Assuming we were able to keep our technology, I have trouble envisioning an
advanced civilization capable of altering its own evolution that wasn;t also
constantly intermixing.
