Did cooking make us human?

The video, “Did cooking make us human?” showed how the foods affected human. Australopithecus spent most of times for eating because they usually ate fruits, which has not much calories in it. Every animals have their appropriate figure to survive and Australopithecus as well. However, 2.8 millions ago human changed to eat cooked food which brought lots of change. Typically, it was easier to digest and get more nutrients. Scientists had an experiment with a snake to figure out that the cooked food is easily to digest. They put raw meet and cooked meet to the snake and the result was the snake easily digested the cooked meet. In another experiment, row food and cooked food, cooked food brings more calories to burn and more calories to store. Cooked food gave more energy. The huge change of eating cooked food brought bigger brain to human than before so that human became more intelligent.
