Hi everyone, always a lurker here but I still read a lot. It seems I just can't go off this forum!
Anyway, in a couple thread I read I saw creationists ask or evolutionists argue on how we became bipedals. I liked, and still like, the idea of climate change for it but Dr Isabelle Winder and her team came up with a new idea. I'm sure some of you are already aware of it but for the others :
Hominins, our early forebears, would have been attracted to the terrain of rocky outcrops and gorges because it offered shelter and opportunities to trap prey. But it also required more upright scrambling and climbing gaits, prompting the emergence of bipedalism.
Info found here
Interesting isn't it?

contradictions
Hominids walked upright before the Savannah ecological change occurred, thus bipedalism was not developed for that ecology (predates it), rather it's prior occurrence enabled hominids to take advantage of the changing ecos.
I find the statement:
quote:
... it offered shelter and opportunities to trap prey ...
to be self contradictory.
I also find that when humans scramble over rock piles they tend to revert to using four limbs ...
In short I am not convinced by this article.
Enjoy
