Hi Geoff, 
Nope. I'm not talking about a shoreline theory. I'm talking about the data
presented in both books I cited. They are written by Stephen Oppenheimer and
explore genetic data. 

Can you give me some sources on lean sea mammals? What about lean fish and
seafoods? 

Humans made their way from Africa to Australia at least 60,000 years ago,
but they wouldn't have the ability to catch deep water fish? 
Sorry. That stuff smells like used oats and I'm not buying. 

If humans hunted, killed, and ate wooly mammoths and other large grazing
animals they would have gotten lots of fats from the marrow of their
enormous bones, their brains, etc. The reason it is relevant to our
discussion is that it was a plentiful source of fats year-round. Even the
horses and aurochs that you assert as the staples of the Paleolithic diet in
Europe would have large bones with lots of fatty marrow. North American
Natives used wasteful buffalo jumps to kill large numbers of bison. They set
up primitive rendering plants on the spot and rendered the precious marrow
fat right away. They dug pits, lined them with hides, and filled them with
water. They smashed the buffalo bones and added them to the water. Then they
built a fire surrounded by rocks. When the rocks were hot, they were rolled
into the pits to heat the water. This caused the fat to rise to the top and
be skimmed off. 

Best Wishes, 
Ron

Ah, you're talking about the shoreline-theory. I'd forgotten about that one.
It seems to be a sort of compromise between the aquatic ape and the standard
theory. Still, I do know of plenty of Palaeolithic sites which are based far
inland(albeit probably never too far from rivers).

 

Last I checked, seafood is generally viewed as very lean. The only exception
are deepwater fish but those presumably wouldn't have been caught in palaeo
times, given the lack of ships, until recent times.

 

Re claims:- The claim that in palaeo times, there were large mammals with
higher fat-content which then died out isn't relevant, really. For one
thing, wild horses and wild aurochs(the ancestors of modern cattle) were
staples of the Palaeolithic diet, at least in Europe, and they are still
around today with the same levels of fat(if grassfed).
