I don't disagree with these statements.  However, the most relevant (and to
me the most interresting) issue is still the "if" of the first statement.
And it is a pretty big "if" in my opinion.  Paleolithic hunters must have
been exposed to rennet cheese from time to time, but just how often they saw
it and whether or not they ate the stomach contents of their prey to begin
with are questions left to be answered.  My own intuition and speculation
aside, I have never heard mention of ancestral cheese consumtion (regular or
otherwise) by any of the authors I've read (Audette, Cordain, Eaton).
