This "tree" shows the relationship between every biological species on Earth in reference to their origin...In evolutionary terms, a common ancestor. This tree also takes into consideration the genetic and physical traits and differences in every species and organism on the tree. Hope this helps : )!

All of these changes get transmitted and processed in the brain and nervous system in general.

A) neurons in the brain are communitive via and has an electrical impulse and is neurotransmitters specialized cells known as neurons transmits signals to different parts of the body
