WebOf the five microevolutionary mechanisms (in addition to mutation), natural selection seems most plausible for the gain in function that resulted in trichromatic vision. Natural selection is the mechanism by which beneficial traits are favored and become more common in a population over time.

Microevolution is the change in allele frequencies that occurs over time within a population. This change is due to four different processes: mutation, selection (natural and artificial), gene flow and genetic drift. This change happens over a relatively short (in evolutionary terms) amount of time compared to the changes termed macroevolution. WebAssumption 1: No Genetic Drift.
