I have been following (with about one eye) the aquatic ape thread on
sci.bio on Usenet.  Most of the posts are devoted to yarn-spinning and
just-so stories pro and con.  I do wonder how proponents of the aquatic
ape scenario would respond to the following:

According to the DNA clock (and the figure on about p. 20 of _The Third
Chimpanzee_ by Jared Diamond), the split between the gorilla clade and

could climatic events in the late Miocene (ca. 7-5 Ma) have anything to
do with autapomorphies of Homo?

Unless, of course, we are willing to admit massive and homoplastic
reversals in both the gorilla and (chimp,bonobo) clades ...
