How Do You Think About the Brain in Evolutionary Terms?

Paul mc lean: Why don't we even have a brain? i was just really interested to try to understand why, you know, why did brains evolve. And what is the brain's most important job? What is a brain really good for? The evolutionary story that molecular geneticists and anatomists and so on, cologists have crafted has been very cool and interesting drama. But this is actually what is going on under the hood. When your brain thinks and decides and sees and hears and feels, it's doing this in the service of the regulation of your body. That turns out to be a really important insight.
