Thanks for the clarification. As I look at that partial skeleton I wonder how anyone could draw conclusions about how it moved even if it were one individual. No knee joints, no hip joints, a crushed pelvis that was assembled and reassembled until it was “just right”, no ribs or spine....yet somehow out of this hodge podge an Ardi hobbles forth.

No doubt you are correct in pointing out there's plenty of room for error or different interpretations.
These don't particularly concern me, because in due time new fossils will likely be found, to help confirm or correct whatever is interpreted about these particular bones.

It's how science works.
