Things You Would Like To See

Science Daily has an item concerning the Laetoli foot print study in PLoS One. One bit stands out:

The subjects walked both with normal, erect human gaits and then with crouched, chimpanzee-like gaits.

Film of the latter would be interesting – lord knows we were disappointed with last year’s Ardipithecus special on that score… Speaking of, why is the idea that some of our ancestors were bipedal on the ground but still spent a lot of time in the trees news?

And then there is this (also from Science Daily):

This morphology differs distinctly from our own genus, Homo, who abandoned arboreal life around 2 million years ago and irrevocably committed to human-like bipedalism.

I guess Homo habilis don’t count, eh? I hope the PLoS One article is better (I haven’t read it yet).

  1. Flawed experimental design: having human subjects walk with a BKBH gait is like asking humans to knuckle-walk on their hands, and then claim they don’t do it as well as chimpanzees.

  2. Yeah, that is my thought as well. It doesn’t really compare biomechanically, to the way people such as Stern and Sussman suggest Australopithecines would have walked.
