Elaine,
I'm not sure if mny other message posted. It shouldn't have, I wasn't
finished. In any case, you made your case well, but I hope you'll forgive
me if I wait for the fossil evidence to back you up. I will keep and open
mind and ask one question in the meantime...

If chimpanzees exhibit occasional bipedalism in a forrested environment,
isn't it possible that this adaptation in hominids may have been more due
to life in the forest, rather than an aquatic adaptation?
