Question 1

Why did cooking make humans evolve bigger brains?

Accepted Answer

Cooking partly digests food before it is eaten, making far more calories available with less chewing and gut effort. This let our ancestors shrink their energy-hungry intestines and divert the saved energy toward growing and powering a large brain.

Question 2

When did early humans first start cooking food?

Accepted Answer

The oldest strong evidence of controlled fire comes from Wonderwerk Cave in South Africa, roughly one million years old, and a hearth site at Gesher Benot Ya'aqov in Israel from about 780,000 years ago. Some researchers argue routine cooking only became common around 400,000 years ago.

Question 3

Who proposed that cooking made us human?

Accepted Answer

Harvard primatologist Richard Wrangham proposed the cooking hypothesis in the late 1990s and developed it fully in his 2009 book Catching Fire. He argued that cooked food, by being easier to digest, fueled the evolution of the human brain and body.
