For this assignment, we will be addressing an interesting subject in evolutionary biology: the question of sexual selection. Very often, we see clear differences between sexes in many varieties of animals (including differences in size, coloration, behavior). For example, see the duck species and peafowl below:
This has been an area of inquiry dating back to Charles Darwin and Alfred Russel Wallace. Dr. Melinda Weaver alluded to some of this in her own research in the introduction to module 4 (where she discussed her research with birds and coyotes). For this assignment, you should find a case of ‘sexual dimorphism’ and write a short research paper delving into the evolutionary questions surrounding the differences between the sexes. You should attempt to explain why it is that a dimorphism occurs between the sexes of the species you choose.
