I'm driving home listening to a story on NPR about finding some bones 1.7
million years old in Georgia (Russia, not US).  This is news because it
wasn't believed that man left Africia that soon.  One of the voices on the
story speculated that a reason for leaving Africa might have been that
humans were getting "a taste for meat".  Huh?

I'm convinced early mankind never ate Gummy bears or processed foods, but
how do we really know what early humans ate and in what ratio?   If I'm to
trust a Paleo diet, then I as a non-scientist am putting my faith into
scientists that believe in this style of eating.  Ten years ago I put my
non-scientific faith into nutritional scientists that hyped a low-fat
complex carb diet.  Along the way there were several other diets.  Forgive
me if I'm untrusting.  I'm about 90% convinced that the Paleo diet as
presented in Neaderthin is solid.  The 10% doubt I'm faced with is the
assumption that we know what mankind ate many many years ago.  How do we
know?
