How does the evolutionary perspective explain the biological basis of behaviour.

Expert Solution

• Evolution refers to gradual and orderly biological changes that result in a species from their pre-existing forms in response to their changing adaptation demands of their environment.

• Physiological and biological changes that take place as a result of evolutionary processes are so slow that they become visible after hundreds of generations.

Two important features of modern human being include:

• A trigger and developed brain with increased capacity for Cognitive behaviours.

•Ability to walk upright on two legs and free hands with a workable opposing thumb.

The environment demands had to biological and behavioral changes over a long period of time. In the human brain, the earliest to the most recent structures in the process of evolution are: Limbic system, brain stem and cerebellum are the oldest, and cerebral cortex is the latest developed.
