Brain Gene Tops the List for Making Humans, Human
by Courtney Sexton/Smithsonianmag.com
Why do humans have such large brains? This evolutionary mystery has challenged scientists for ages, but some researchers are using genetics, specifically those genes that can only be found in Homo sapiens, for an answer.
Having more folds in this part of the brain is important because those folds increase the surface area available for brain cells, or neurons, without making the brain too big for the skull. Demonstrating that the human gene fulfills a similar purpose in the brain of another primate provides new insight into how humans may have evolved and may point the way to future treatments for brain disease.
