Food, glorious food! Whether you’re a sneaky snacker or a mega meal muncher, all humans need food to survive. But why do we keep searching for new ways to prepare mouthwatering delights?

Cooking a mean feast as opposed to eating raw food has led to many evolutionary changes in the human body, as the University of New South Wales’ evolutionary biologist Darren Curnoe explains in the video below.

Raw potatoes, as an unappetizing example, contain poisonous toxins and harmful bacteria, such as solanine and E. coli, which can result in abdominal cramps, diarrhea, nausea, headaches or even death if consumed. But boil ‘em, mash ‘em or stick ‘em in a stew and the food is safer to eat and easier to digest.
