Fire and Cooked Food

Fire and Cooking Header

Making & Controlling FiRE has been a hugely significant factor in the evolution of man.
The ability to make & control FiRE would've not only kept us warm, provided light, but also allowed us to start cooking the food we hunted, gathered & later grew.
It's believed that cooking our food might have been the reason why our brains grew much bigger than other evolving species.
Food, such as fruit, vegetables & meat is tough & fibrous to eat raw. Cooking makes food quicker & easier to eat as well as easier to digest. Eating cooked food uses less energy than eating raw food.
One theory states that eating cooked food would've allowed our evolving guts to shrink over time. The energy that would’ve gone into supporting a larger gut might instead have contributed to the evolution of our big brains.
In other words, when we started cooking food it may have allowed our brains to grow.
Brain tissue requires 22 times the energy of skeletal muscle. It would be hard to get enough energy from raw food to support our big brain.
Modern Humans need to eat cooked food, which provides the high-quality calories they need.
