A note on a slightly updated format for articles. We are going to start posting almost all articles with a "click to continue reading" link and will only be posting the first few paragraphs of the main article with perhaps a short note to help put it into context if necessary. When readers submit articles they often send in a sentence or two along with it explaining the context or why they feel it's particularly pertinent and we'll also post that if appropriate.

Q. IN YOUR NEW BOOK, YOU SUGGEST THAT COOKING WAS WHAT FACILITATED OUR EVOLUTION FROM APE TO HUMAN. UNTIL NOW SCIENTISTS HAVE THEORIZED THAT TOOL MAKING AND MEAT EATING SET THE CONDITIONS FOR THE ASCENT OF MAN. WHY DO YOU ARGUE THAT COOKING WAS THE MAIN FACTOR?

A. All that you mention were drivers of the evolution of our species. However, our large brain and the shape of our bodies are the product of a rich diet that was only available to us after we began cooking our foods. It was cooking that provided our bodies with more energy than we’d previously obtained as foraging animals eating raw food.

I have followed wild chimpanzees and studied what, and how, they eat. Modern chimps are likely to take the same kinds of foods as our early ancestors. In the wild, they’ll be lucky to find a fruit as delicious as a raspberry. More often they locate a patch of fruits as dry and strong-tasting as rose hips, which they’ll masticate for a full hour. Chimps spend most of their day finding and chewing extremely fibrous foods. Their diet is very unsatisfying to humans. But once our ancestors began eating cooked foods — approximately 1.8 million years ago — their diet became softer, safer and far more nutritious.
