full title, "Walk like a man: Fossil raises puzzling questions about how upright body plan of great apes evolved".

The fossilized hipbone of an ape called Sivapithecus (photo 1) is raising a host of new questions about whether the upright body plan of apes may have evolved multiple times. "What we do know is that the evolution of the orthograde body plan in apes is not a simple story," noted Harvard's Michele Morgan (photo 2), co-author of the paper.

Walk like a man, talk like a man......but sing like a girl? Strange song.

form follows function... if a particular body plan gives an advantage you shouldn’t be surprised to see it multiple times

It came about when the females kept asking the males to get something off the top of the trees.
