Summary

The Social Brain and Human Evolution

Samuel Taylor Coleridge, an English poet, pointed out that a tiger remains the same whether it lives alone or among thousands of other tigers. A tiger is just a tiger. But humans are unique. According to Coleridge, our relationships with others change us in fundamental ways. Without these connections, we wouldn't develop skills like understanding emotions or picking up on social cues. Today, this concept is called the "social brain."

When people casually refer to the brain, they usually mean it as a single unit. However, neuroscientists explain that we have a "triune brain," which means three brains in one. These three parts represent different stages of evolution. 

  • The first part called the reptilian brain developed early and is centered around basic survival functions like breathing and heartbeat. 
  • The second part, the mammalian brain, formed around the reptilian core and introduced emotions, enabling behaviors like caring for offspring. 
  • Finally, the outer layer called the cerebral cortex emerged.
