February 6, 2015 – Natural selection: Darwin’s four postulates. In the past few days, we’ve gone over how evolution can occur through mechanisms like mutations, gene flow, and genetic drift.

Natural selection is the process in which living things with beneficial traits produce more offspring than others do. This results in changes in the traits of living things over time.
