Guts

Very early in our evolution we developed colour vision which gave us a huge developmental advantage in choosing ripe fruit.

With our three types of colour receptors, our eyes can see up to a million different colours. Our colour vision is a sensory gift. There are relatively few other mammals that see all the rich and varied colours that we do.

How the need and search for food has changed our, and our ancestors, lives. This hunt for food has shaped much of our lives.

The Hadza love meat when they can get it, but it’s not a reliable source of food. Only one in 29 Hadza hunts is successful in terms of the men coming home with big game.

How evolution and our meat-eating diet has shaped our faces as well as our bodies.

Omnivorous humans began eating meat and developed smaller teeth and jaws which in turn produced a slimmer more gracile face.

Why does Homo sapiens have a bigger brain than earlier men? How could fire fuel brain expansion? Cooking and eating red meat appears to be the answer.

Recent research suggests it was cooking, not meat, that fuelled the evolution of our big brains. It was cooking that made us human.

The practice of partnering for life has more to do with food than it does with procreation and still affects male behaviour today.

Men are show-offs and have been since early history and with good reason, the family survival depends on it.
