The Evolution of New Brain Regions

Cheesec says the brain evolves as a whole, with older parts undergoing modifications to adapt to the addition of new parts. The best supported explanation for the origin of new brain regions was that they evolved mostly by duplicating and modifying pre-existing structures and neural circuits. Cheesec: When new things happen, there are elaborations of older things. Not just add a new module on top. It's not like upgrading your iPhone.
