The pH of human stomach acid is on par with that of many scavengers, such as vultures.
Anthropological evidence indicates that early hominids, as they began their transition to a more carnivorous diet, were feeding on the left overs from other carnivorous predators - which would explain the need for such an extremely acidic stomach
Fascinating, does that mean vultures are just as susceptible to e.coli, salmonella, etc as we are? I always presumed they could handle "slightly spoiled" meat without food poisoning better than us.
