I suspect this is nonsense, although understandable. The Australian aborigines
may be a good example of a hot-savanah living race as far as getting hot is `
concerned. They do not drink frequently during the day, although they
do urinate reguraly. They manage to do this by spending their mornings
drinking huge amounts from the local watering hole. They don't drink again
I suspect that a good explanation for the hairlessness/fat business may
go as follows: The advantages of fat are: insulation, energy storage.
The disadvantage is that it slows you down, more energy to move around.
Obviously fat apes would have trouble climbing trees. A disadvantage of
thicker fur is that it is a suitable habitate for lice, fleas etc.
==> You would expect apes to have their hair thin out, and gain fat if they
stopped climbing trees so much, and were able to feed themselves easier.
Further, is sweating a superior for of heat loss?
I seem to remember someone saying that men have more hair than dogs.
(number wise, possible count density).
Someone made a post commenting that having skinny legs did not make sense for
being an A-ape. I point out that in wadeing, it is better to have your
One final point, could it be that the AAT ers are suggesting that the AA was
