Natural selection is a process by which a species changes over time in response to changes in the environment, or competition between organisms, in order for the species to survive. The members of ...

To constitute natural selection, the difference in survival and/or reproduction cannot be due to chance, and it must have the potential consequence of altering the proportions of the different ...
