An interesting recent article in the Yearbook of the American Physical Anthropology Association by authors from Tel Aviv University, that presents fairly extensive data from over 400 papers, showing that humans and their ancestors were very predominantly carnivores, with very modest plant consumption early on, that only gradually increased late over the last 2 million years or so.
One of the central points in the article is that the early human stomach had a very low pH, a common finding in carnivores, and not a typical finding in herbivores. The low pH helps protect the carnivore from ingested bacteria in decaying meat, that was quite common before the advent of refrigeration. As I mentioned in earlier posts above, carnivores, ( and omnivores ) have very different dentition and bowel dimensions that most wild herbivores. Indeed, our fat stores are those of carnivores, not herbivores according to this article as well.
I post this not to suggest that a carnivorous diet is preferable, just that there are a substantial number of published scientific articles suggesting that humans evolved from carnivores, millions of years ago, and that the adoption of plant food stuffs came after much of the largest game had been eliminated by humans hunters...
One comment from Dr Ben-Dor I can't resist quoting.....
“Hunting large animals is not an afternoon hobby,” says Dr. Ben-Dor. “It requires a great deal of knowledge, and lions and hyenas attain these abilities after long years of learning. Clearly, the remains of large animals found in countless archaeological sites are the result of humans’ high expertise as hunters of large animals."
Imagine yourself, sitting by a campfire in the dark, knowing that when the sun rises next, you and a couple friends are going to pick up spears and atttempt to slaughter a mammoth.... One reason why hunting was surrounded by strong rituals, perhaps.
I ate no meat today.
