Evolutionary History

The branch of biology that studies the origins and changes in the diversity of life over time, explaining how and why species have evolved and become extinct.

Limbic System

A complex system of nerves and networks in the brain, involved in instinct and mood. It controls basic emotions (fear, pleasure, anger) and drives (hunger, sex, dominance, care of offspring).

Brainstem

The part of the brain that connects the spinal cord to the rest of the brain, controlling many basic life functions such as breathing and heart rate.
