Does this suggest that man evolved from modern chimpanzee?
No. The exact line of descent is still being worked out, but it is certainly not from modern chimpanzees. (Chimpanzees have evolved a little also, but forest fossils are pretty difficult to find. Genetics are probably a better field to use for these relationships, much as I love bones.)
Gotcha.
Just seemed a bit odd to be listed there. Not picking a fight.
There's also this problem with living in lateritic soil. Much of Africa, as well as the American South, have such soils.
