'New' Theory about Human Evolution.

[swestrup]

According to this article it seems there is a new theory about that not long after we first walked upright, selection pressures molded humans into the long-distance runners of the ape kingdom. I first heard this over 20 years ago. Why is it news now?

I have a theory that humans evolved an upright posture 'in order to' connect their heads to their feet. Technically, of course, this is an inaccurate description; it's more precise to say that after the human head rose to its current height, those with a horizontal spine were quite spectacularly and indeed messily disfavoured.

Time will tell whether the (recent, in evolutionary terms) invention of climbing gear will eventually reverse this trend.
