Today in history — Chewing!
Cooking is something we all take for granted but a new theory suggests that if we had not learned to cook food, not only would we still look like chimps but, like them, we would also be compelled to spend most of the day chewing.
Without cooking, an average person would have to eat around five kilos of raw food to get enough calories to survive.
The daily mountain of fruit and vegetables would mean a six-hour chewing marathon.
It is already accepted that the introduction of meat into our ancestors’ diet caused their brains to grow and their intelligence to increase.
Meat – a more concentrated form of energy – not only meant bigger brains for our ancestors, but also an end to the need to devote nearly all their time to foraging to maintain energy levels.
As a consequence, more time was available for social structure to develop.
If God didn’t want us eating animals he wouldn’t have made them out of meat! Go team carnivore!
