Linguistic analysis also suggests the Kalahari Bushmen are the oldest race on earth.

One of the things I found interesting about the article was their argument in favour of a high proportion of seafood, with migration routes tending to be around the coasts. I think it is probably quite valid.

I just can't see shore caught fish (without nets/hooks/fishing poles) ever being an kind of match for big 4 legged herbivores with regards to calories expended for calories gained.

I can. Seafood, crustaceans & birds eggs are a much more easily accessible & less dangerous way to get good quality protein, plus they wouldn't have to expend much energy to get them. Women & kids would be collecting/harvesting them, while the men were out trying to bring down the big game. If they returned empty-handed (which was around 75% of the time, according to speculation in the article), they would feast on scallops & other water critters. Until we'd perfected prey-specific hunting techniques in our genus and in Neaderthalensis, I'd think that bringing home big game was more luck than actual skill. Plus, seafood of some kind is almost guaranteed to be available, unlike the larger land animals.

The answer to your question is 'eat more fat'.

Stop counting calories. If you are eating Paleo, there is usually no need.

If you are having weight loss issues, it'd be a good idea to start posting a detailed food journal, then everyone can help.

'Anecdotal Evidence' is an oxymoron.

And, like I said, the women and children were the ones most likely to be doing the gathering, the men out hunting. The women and older kids would not be sitting idly around, waiting for their ape-hubbies to come back, without having made some contribution to their meal.

The hominids leading up to erectus and ergaster were not skilled enough to hunt, which is why they would have no doubt relied on scavenging and collecting molluscs, fish, eggs, and other protein-packed goodies that could easily be scooped up from a tidal pool or shore line. It would have contributed to their growing brain sizes, given them more kcals than vegetation, and were good sources of minerals. Those would have been the perfect and most logical intermediate food stuffs during the transition from herbivore to omnivore which manifested itself into true omnivorism with ergaster and erectus.

That is true. I guess I mostly look at these things to see what our macros should be, which means not looking too far back, or too far forward.

I try to encompass a broader view ;) Our evolutionary history is like a story. Players get killed off and new characters rise to the fore. When I look at our diet and that of our ancestors, and how it developed, I try to find commonalities. And one thing that most animals are notorious for, is taking the shortest route possible to get to their destination. When you're talking about proto-humans, they hadn't developed the 'warrior culture' that we have over the millennia, so risk-taking for societal gain (like a manhood rite of passage in tribes) wasn't a big factor in their food acquisition. Greed (in an animal context--ie, "pig out on antelope because it tastes good!") and/or desperation drove them to go after larger and riskier game and over time this method became commonplace and this trait was encouraged in order to survive.

And that's why we have the Roman Coliseum, lol.

A warrior culture is not required, with regards to our current form. Killing big four legged mammals was the most efficient use of their time and energy. In fact the most plausible scenario, to my mind, would be carrion eaters who upgraded to chasing the predators off their kill, then upgraded further to doing the killing themselves.

Most likely the women would have been hunting with the men for most of the paleolithic.  It's even possible that the women hunted and the men did the territorial defense, like lions do.

Except that, as far as we can tell, they mostly didn't live on the shoreline.  Also, once you go back before erectus, or at least before habilis/georgicus, you're into the australopithecines and they were before the paleolithic.  Given their large guts and small brains, they were clearly adapted to a different kind of diet than we are adapted to.

I'm with you on this.  And we are still doing it -

If your food needs a prefix, it's not paleo!
