Thinking Like an Anthropologist Essay:
Brainy Chefs-How Cooking Ignited the Evolution of our Brains

Context of the Assignment:

Two million years ago a gene mutation MYH16 was introduced into the hominin population. This mutation rendered the gene responsible for producing some jaw muscles used in chewing and bite force inactive. This weaker jaw could have resulted in our extinction but Richard Wrangham argues it might be one part of the mystery for how hominin evolution resulted in modern humans having a large brain size but this is only one part of the story.
