A study found that great apes prefereprefer cooked food, which refutescontradicts the notion that the preference results from human evolution.
Cooking food properly is generally beneficial for nutrient availability and taste, so the cooking itself is not what causes the animal preference: pulverising with a blender would have some similar effects on preference. Animal preference is based on sensation of sugar, fat, salt, aromatics, which generally are higher when the cells of the food matter have disamalgamated and volatilized.
