So, a few fossils of "Ardi," the early hominid with bipedal capability, are found in what is determined to be an ancient woodland environment. This leads to the conclusion that hominid bipedalism evolved in a "woodland hominid" as opposed to a "plains hominid." Well.... maybe. Any problems with this interpretation? Is there an alternative explanation?

 

Answer:

Ardi's body structure revealed that she had long arms and fingers and opposable great toes. Her pelvis and food exhibit many features characteristic of later bipedal hominids, as well. She was believed to have walked upright and may have also partially lived in trees in a woodland habitat. The facts presented by her body structure and where she, and other Ardipithecus ramidus, was found all point to the probability that hominid bipedalism evolved in a woodland setting.
