Question

This question is based on the evolution of mating systems in different species. I'm mostly having trouble understanding what is being asked in question 3.

**Peacock Spider Mating Behavior**

Male peacock spiders engage in elaborate courtship rituals on small territories they defend. They display a flat posterior lobe with vibrant, contrasting colors on their abdomen. During courtship, males perform a dance, tapping their feet in a rapid rhythm on the ground, and produce vibrations akin to "singing."

Interestingly, female peacock spiders can express their disinterest dramatically by eating the male.

**Reproduction Details**

- Fertilization is internal.
- Females lay egg sacs and protect them until hundreds of spiderlings hatch.

**Discussion Questions**

1. What kind of mating system would you predict for this group of spiders?
2. Under what circumstances would you expect the mating system to evolve into an alternative system?
3. Propose some alternative hypotheses for how female mate choice may be maintained in this current system.

Expert Solution

Step 1

Mating in living beings is part of sexual reproduction. It is of two main types which are random and nonrandom mating. Random mating includes chance mating between individuals rather than having some preferences.
