Four postulates of natural selection.

The shift in the heritage characteristics of a population over time is a crucial factor for evolution. Charles Darwin popularized the term ' natural selection'.The basic postulates of Darwinism are: (i) Enormous power of fertility: Every living organism has the power to reproduce rapidly.
