[eli5] Why did humans advance so far so fast while other intelligent animals did not?
In: 944
Eating protein, specifically protein cooked in fire, provided a substantial boost to our brain development. Cooking animal protein in fire allowed our digestive system to more readily absorb nutrients. Raw food is not broken down enough by the time it reaches the large intestine, where the lions share of the nutrients are then consumed by the microbes and bacteria living there. However cooked meats are broken down inside the stomach and small intestine sending valuable building blocks to the brain.
