Evolutionarily speaking our physical makeup represents a complete set of adaptations to factors in our environment. My question is: for what percentage of the time humans have been around on this planet in our present form have we had access to fire and therefore cooked food?

We've had fire for about a million years, or about twenty times longer than our present **** sapiens sapiens has been in existence. We don't appear to have any specific adaptations for eating cooked food, versus eating stone-pounded raw food.

The real sad truth is that before human learned to cook fresh meat, the only meat they ate was what they could scavenge after is was pretty well decomposed and the fresh meat predators left the carcass.

I'm not making this up. This is how it was. Humans do not have the right kind of teeth to eat raw meat. At some point in time, probably when a forest fire burned some meat for them, they learned that cooking tenderized it.

The use of fire to cook meat may be as remote as the hegemony of dinosaurs on earth.

Tyrannosaruses, being able to walk on two feet and to use their hands, seemingly ate meat everyday and can be treated as early humans --- because today's science says that the **** sapiens evolved from mammals (primates) which evolved from reptiles. If the **** abilis is considered human and could even not stand on its feet, then why not the t-rex.

Btw, the size of a t-rex brain was larger than that of most other dinosaurs. The T-rex also lived mostly on land, like early humans did, and during a very hot era (it had to be hot in order for dinos to survive in water), and we can guess that fire had better probability of being accidentally ignited at that time (say, just out of a flatulence) than in any other successive era.

If an animal species can desire to eat and can accomplish the necesseray action to kill and eat its prey, then it can certainly desire to ignite a fire so its meat becomes more edible, just like most ducks can decide to dip in water a piece of crusty bread we give them, before they swallow it.
