Evolutionary Biology and the Complexity of Brains
51:49 - 1:04:12 (12:23)
The evolution of brains is not a simple upward trajectory from simple to complex, as the function of the brain is largely influenced by its environment and niche. The niche is becoming more complex and shaped in weird ways.
Clips
The idea that brains evolved in an upward trajectory is called a phylogenetic scale, from simple brains in simple animals to complex brains in complex animals.

Summary
The idea that brains evolved in an upward trajectory is called a phylogenetic scale, from simple brains in simple animals to complex brains in complex animals. Sedimentary rock is a way to think about the cerebral cortex like icing on an already baked cake.

Summary
The development of the head and its visual, auditory, and olfactory systems are closely related to the development of the brain. The evolution of the jaw followed quickly after the development of the head.
