The question is: do we cook because we're clever and imaginative, or are we clever and imaginative because our ancestors discovered cooking? Horizon examines the evidence that our ancestors' changing diet and their mastery of fire prompted anatomical and neurological changes that resulted in taking us out of the trees and into the kitchen. The question is do we cook because we are clever and imaginative, or are we clever and imaginative because our ancestors discovered cooking? Homo Habilis had a bigger brain (50% bigger) than his forebear, Australopithecus. Was this down to his diet? In Did Cooking Make Us Human?, a clutch of determined scientists set out to discover the extent to which diet played a role in the evolution of the human brain, using a variety of mildly alarming gadgets. Professor Peter Ungar has a contraption he calls the Bitemaster Two, a mechanical chewing machine he has fitted out with genuine Australopithecine gnashers. For the first time in three million years they were set to work on a carrot with success. On raw meat they performed less well, unlike the teeth from a later human ancestor. Australopithecines didn't eat animals, skulls with fang holes show that it was the other way round. At some point in our evolutionary history it's clear that we ...
