Question

observation of evolution of brain of vertebrates​

Answer 1

Answer:

The structure of every single vertebrate brain is fundamentally the equivalent. Simultaneously, over the span of evolution, the vertebrate cerebrum has experienced changes, and become progressively successful. ... In warm blooded creatures, and particularly in man, the brain is grown further during life by learning.

Explanation:

The principles that govern the evolution of brain structure are not well understood. Brain to body size scalesallometrically. Small bodied mammals have relatively large brains compared to their bodies whereas large mammals (such as whales) have smaller brain to body ratios. If brain weight is plotted against body weight for primates, the regression line of the sample points can indicate the brain power of a primate species. Lemurs for example fall below this line which means that for a primate of equivalent size, we would expect a larger brain size. Humans lie well above the line indicating that humans are more encephalized than lemurs. In fact, humans are more encephalized than all other primates.

Answer 2

Explanation:

The principle that govern the evolution of brain structure are not well understood. Brain to body size does not scale isometrically but rather automatically . The brains and bodies of mammals do not scale linearly. Small bodied mammals have relatively large brains compared to their bodies and large mammals have small brains.
