Our Reptilian Brain?
Evolution Talk22 Touko 2023

Our Reptilian Brain?

From the quiet roads of New Hampshire, where snapping turtles are more common than lizards, to the depths of our evolutionary past, we'll grapple with the idea that we may still carry a piece of our reptilian ancestors within us. But don't be too quick to believe popular pop-psychology. We'll explore what the Triune Brain model tells us about our so-called "reptilian brain" and how it shapes our instinctual responses. We'll question if there's a lurking Allosaurus within our minds or if it's just an oversimplification of a complex organ.

Evolution Talk is also a book! You can find links to Amazon, Barnes & Noble and others on the front page of EvolutionTalk.com, or call your local bookstore and ask them to order a copy.
