Jaw Muscle and Brains in Human Evolution

There is a gene called MYH16 in both humans and other primates. In humans, this gene is damaged. This makes human jaw muscle fibers one third the size of chimp muscle fibers. It’s a fascinating thing, because this mutation may have made the larger brains of humans possible, as described in this wonderful video here:

It is likely that this gene, or the same kind of mutation in another gene, is affecting the strength of human muscles."
