That Whole "Human Evolution" Thing Needs More Work
Study suggests early upright apes had Darwin fooled
In other words, if this is true, then the very icon of human evolution needs more than a little tweaking!
Answers in Genesis further points out:
[W]alking on thin tree limbs is substantially different than traversing even the spongiest soil; thin tree limbs will not support weight in the same manner. Unsurprisingly, then, the orangutans don’t actually walk “independently” upright; rather, they cling to surrounding branches and tree trunks as they move along.
*Sigh* Pass those textbooks forward again, class! *Snip snip snip*
