I did not mean to imply that individual eskimos evolved. All I meant is
that those who couldn't survive and reproduce in a severely cold
environment with a total lack of plant food and a scarcity of animal
food died, and therefore couldn't spread their genes.

>> 2) Calcium levels have nothing to do with pH of the urine.
They do effect the pH level of urine. The breakdown of protein produces
acids which are then excreted through the urine. Since the pH level of
urine must be maintained, the body excretes more calcium in the urine.
Cysteine and Methionine are the amino acids that increase calcium loss
when consumed to excess, and most people get lots of these two amino
acids from nonvegan foods. I did find some interesting information on
protein, and I'll post it sometime today.
