Is the human digestive system better adapted to digest raw meat or cooked meat?

Best,

Fossil finds have shown that our ancestors used fire to fry meat at least 500,000 years ago (remains of fire and semi-charred bones…).
Our teeth are also more adapted to grinding fried meat than to shredding/cutting raw meat; this is apparent from the relative size of the molars (molars) and the small size of our incisors. Baked meat is much easier to grind than raw meat. Unless, of course, you let the butcher grind meat, then that problem is gone.
Our intestinal tract is not adapted to a pure vegetable diet (as with monkeys), nor to a pure meat diet (as with dogs or cats). The length of the intestinal tract and the size of the caecum, a connection between the small and large intestine, lies somewhere between that of herbivores and carnivores. We are rather omnivores (omnivores).
