Or fat? Where would proto humans get all this extra glucose that
chimps, gorillas and baboons don't? Baboons in particular live in
conditions that proto humans were said to occupy, the open savannah.
Baboons eat a lot of roots, mainly grass rhizomes from what I have read.
I am sorry Amadeus, but I can't buy this line of thinking. Humans
obviously have heavy meat eaters in our ancestery, they were not
herbivores unless you go back several millions of years. The fat from
animals seems to me the only likely source of the concentrated energy
that would have been available for long enough for evolutionary
processes to work. Where are those excellent glucose sources now? They
don't seem to exist on the African savannah. But game is wildly
plentiful. By scavenging fat rich bones or by selecting the fattiest
parts of a hunted carcass to eat there would have been plenty of fat to
supply an oversized brain, with plant foods filling an important role,
but not a sole one.
