PopGen 6: Brief Introduction to Evolution by Natural Selection
... Natural selection is not the only agent for change in allele frequencies. Two potentially important alternatives are MUTATION PRESSURE and GENETIC DRIFT. Under mutation pressure there is a direction to evolution and, unlike natural selection, it is a direct extension of the process of mutation. Unde ...
