Welcome back. These dog-days of Summer have been a bit quiet.

However, I think you missed my point -- which was that great
heat stress does _not_ occur in forests. There's always plenty
of shade, and if you climb you can usually get a breeze.

I should also have said that the other very puzzling aspect of
the sweating mechanism is its extraordinary wastefulness in
regard to salt.

So I'm saying that the sweating response did not develop in a
forested or mosaic environment. We're looking for somewhere
without many trees, with lots of fresh water and a superfluity of
salt. If we hold that nakedness probably developed at the same
time, then it also must stay warm at night.

Now, where might that be . . . . ?
