This discussion isn't very relevant to sci.space or physycs, so I've modified it to sci.space, psychology and bionet.molbio.evolution In article <1153@helens.Stanford.EDU> joe@hanauma.stanford.edu (Joe Dellinger) writes: >One last point: by some standards we aren't even all that successful.

Lucky for us we figured out Watch it: Gould also says (and I agree with him) that our species classification system is very biased. The further away from our branch of the tree we get, the more lax we are about defining species. For example, we and the Chimps are a *lot* closer morphoplogically than some invertatrae that we call "sibling species"; we're also closer than the horse and donkey, which can breed to produce a mule (or is horse+mule=donkey, whatever). The only thing stopping us from interbreeding with chimps to see if we're sibling species is that, right now, most people would be revulsed by the idea. In other words, you and I and the chimps all look the same from a slug's point of view. -- "Dad, what should I be when I grow up?" "Honest." -- Robert M.

Does anyone know if this experiment has been tried? To bread a chimp with humans would pose many ethical questions. But it could provide some answers about many topics including evolution. ***************************************************************************** Neal Norwitz neal@tut.fi What have we learned?

I feel like I should rather look up the following question in a book rather than to allow it to clutter up this molecular evolution list, but maybe someone can settle it for me in short order. It has been my assumption all along that humans and chimps cannot mate. Am I wrong? Surely with all of the human promiscuity during the last half-million years, the products of those unions would have proliferated. Come to think of it I have friends who seem always to make monkeys out of themselves. Hey, while you're at it, how many pairs of chromosomes do chimps, gorillas and baboons have? Oliver.
