### Exploring the Mating Systems of Gorillas and Humans

**Section (A)**
A well-trained alien biologist visiting Earth would be able to discern that the mating system of gorillas is strongly polygynous, while that of humans is weakly polygynous. How could this biologist determine this just by observing gorillas and humans?

**Section (B)**
Is harem polygyny an Evolutionarily Stable Strategy (ESS), or have "cheater" behaviors evolved to exploit or exist within these systems?

**Section (C)**
If your answer to Section (B) was yes, then describe a cheater behavior within a polygynous system.
