Here is a simple story about the origins of the human brain: All primate brains are dense with neurons—they are the supercomputers of the animal world. What's more, the human brain is just what you’d expect from a primate of our size: big, packed with neurons, but no more special than that. It's the chimps and gorillas who are special: without cooked food, their brains lacked the fuel to keep up with the growing body.

Or so argued Suzana Herculano-Houzel, my guest in last week's episode.

In today's episode, paleo-neurologist Dean Falk explains why she thinks this is only part of the story.

I'll let her tell you why.

Enjoy!
