Homo sapiens emerged roughly 200,000 years ago as apex predators. Our physiology was forged in the Pleistocene, an era dominated by large ruminant animals.

The human stomach maintains a pH of approximately 1.5. This is significantly more acidic than herbivores and even most omnivores, a trait shared with scavengers and apex carnivores to neutralize pathogens in meat.
