Natural Selection, Lemmings, and Cannibalism
1) In your own words, describe how evolution by means of natural selection works. Imagine explaining this concept to another OU undergrad who has only little background in biology or to your parents (who are, presumably, not biologists). Integrate your answer in addressing the following two questions:
2) What challenge does the cyclical, suicidal behavior of the lemmings pose to Darwin’s theory? How might the behavior be explained?
3) Could cannibalism evolve and/or be maintained via natural selection? [Note: think beyond human cannibalism]
