Natural Selection Lab This hands-on laboratory exercise is a highly simplified model that attempts to simulate evolution by means of natural selection. Predators will act as agents of selection on their prey‚ a species whose members vary in color. We will assume that color is an inherited trait. Small squares of paper will represent the prey‚ which will be spread out of a piece of printed colored fabric that will serve as the habitat. The predators (you) will prey upon the population‚ with the surviving

Reproduction is seen as an expensive ordeal which has potential of exerting a considerable evolutionary pressure. This pressure was portrayed by Darwin as sexual selection operating through some members

described them as resulting from “sexual selection”. Sexual selection is both different from natural selection and a mechanism of natural selection. Like natural selection‚ variation in individuals is the driving force behind the differences in their survival and reproductive success.
