The evolution of humans has been a subject of numerous discussions, books and publications during the recent years. One interesting theory claims that what actually made us humans was cooking. The author of this hypothesis is Richard Wrangham who is a primatologist from Britain. In 2009 Wrangham published a book called “Catching Fire: How Cooking Made Us Human”. He claims that the evolution of humans was triggered by cooking.
No other species except human beings cook their food. According to Wrangham, cooking was an essential factor in the development of humans because this trait let our ancestors reduce the time they spent for chewing and digesting food. Thus, the digestive system of human beings became more effective and able to provide energy for further growth and development of the brain.
Wrangham claims that the ability to control fire and cook food also allowed our ancestors to start living on the ground, which led to further evolution. In addition, the British scientist argues that humans wouldn’t be able to reproduce if they ate uncooked food.
