"These "assertions" were simply my statements repeating what was said in
the program. You got a problem with it, contact the guy making the
assertions in the program. You've got the link to PBS."
Ok, here is all that is said on the topic of animals being fed grain as
being the basis for the rise of complex cultures, you went in with a bias
and yu heard what you wanted to, and you didn't hear what was really
said; thus the baseless assertions:
"We know that the communities which first started to
have domestic animals already had cereal crops, so they were
cultivators, and the combination of these particular animals and
plants becomes an extremely attractive package, in that they're
complementary. After the harvest period, animals could be turned out
on the stubble, and they can actually eat the remains of the cereal
crop harvest. In their turn, animal dung can be used to provide sort
of a fertilizer for the cereal crops as well, the crops, so the whole,
the whole package, you know, is seen to be mutually beneficial, both
for the animals and the plants and of course for the humans."
