Changes on genetics of a specie and is inherited by the biological population.

Biological Evolution
Rules of natural selection
Every specie is made up of variety of individuals wherein some are better adapted to their environment over the others.
Produce progeny with different set of traits that can be inherited.
Organisms that have traits most suitable to their environment will survive and transfer this traits to their offspring in subsequent generations.
