I have one final question for Richard. Now you are doing what you accuse me of. It is not 'well known' at all. Human feet are flat for walking upright. OH 8 and Stw 573, discussed below.
Ape teeth are characteristically different from human teeth.
You don't present any data to show that my claim that A. africanus most resembles humans is wrong. You ignored it and went off on a long tangent about how apelike Lucy's teeth are, something I largely accept. Few humans are smaller than 900 cc. See my earlier remarks about brain size. But no-one says that absolute brain size is correlated with intelligence.
