The primatologist Robert Wrangham worked out that our brain consumes a fifth of all our energy. If humans were to hunt and gather this many calories
themselves, it would take at least nine hours of each day, and gorillas spend 80% of their time chewing vegetation. Humans as we moved through the millennia of civilization ate
a wider variety of food, from basic sustenance through to indulging in all types of epicurean delights. In Michael Pollan’s book ‘Catching Fire, How Cooking Made us Human,’ his
observation tracks the transformation of vegetables through heat in the cooking process which also acts as a steriliser to kill bacteria. The taming of fire through cooking has
changed everything about us, from the size of our teeth to the functioning of our brains, to our social organization. Fire further shaped the dynamics between sexes and division
of labour divided the work of the household.
