There is no compelling reason to explain all of those things in
terms of a single adaptive response since there is no evidence
that they occurred at the same time. The only one we know for
certain is bipedalism. The rest could just as well have been
recent (within the last 200,000 years) changes.

Your constant emphansis on convergence ignores that fact that it
is not all that common and is certain not the driving principle
of evolution.

I see a cartoon of a family of gorillas taking a vacation
at the beach. The mother gorilla shouts at the youngsters
"Stay out of the water or your hair will fall out!"

What exactly is the connection between wading and hairlessness,
pat? How can you argue that wading and occasional diving will
produce convergences with whales, dolphins and manatees?
