Question
Chapter 44.4, Problem 4R
Summary Introduction
To review:
The maximum increase in a part of the brain while comparing mammals, fish, and reptiles.
Introduction:
Mammals perform a lot of complex functions, which require the formation of a lot of synapses inside their brain. On the other hand, fishes and reptiles have to perform the functions that are just necessary for their survival. High cognitive functions like planning, thinking and others are not the main tasks that have to be performed by lower vertebrates.
