One phenomenon that is very common across insects (and other arthropods) is that when it comes to mating, females are often the choosier sex. This week’s required reading, lecture, and discussion should have provided some insight into this.  Explain in your own words why, in arthropods generally, evolution has led to females being choosier than males, and why males are generally more willing to mate with multiple females. In your answer, be sure to describe the process of sexual selection (starting from gamete size all the way to selection of mates). Explain your rationale clearly, as if you were explaining this phenomenon to someone with little background in biology.
