I believe the hypothesis put forth by Rob Blumenschine is that early
hominids were opportunistic scavengers, finding sources of protein and
fat in a part of the carcass the other predators and scavengers could not
get at: the marrow inside long bone shafts, which is rich in fat. In
order to access this marrow, early hominids would need to use simple
stone implements which could splinter the bone shaft... if the carcass is
relatively fresh, the marrow should be as well. This came from (and I am
rather reluctant to admit) one of the "Ancestors" NOVA installations. Anyone
have published citations of Blumenschine's research?

Anyone care to summarize the AAT as a refresher?
