Humans artificially select the traits they want in the population.
Natural selection is sometimes harder to imagine, although it is a fairly straightforward concept.
What is more difficult is an appreciation for the effects of natural selection within a population over time. The purpose of this lab is to set up a simple simulation of natural selection in a predator - prey system. Students will feed individually. These variations represent genetically fixed differences in the population. No scraping or pushing of the prey into the mouth is allowed.
