JW: Yes. This confirms the Jolly and Plog study. But
according to Susan, C. Owen Lovejoy also carried out a
biomechanical study of this species and apparently reached
an entirely different conclusion. So who are we to believe?
Is Christine Berge a qualified physical anthropologist?

And more importantly, where does that leave us regarding
Paul's original question on the matter? Don't tell me he's
been proved right once again.
