While watching TV with your mom, you see an advertisement for a show depicting polygyny. Your mom says that polygyny isn’t natural. What evidence do you give your mom that her statement is false?

E. O. Wilson say polygamy is natural

Explanation:

There are a number of ways to prove polygamy is natural, actually. The most meaningful one would be when you literally look at the number of mates that are simultaneously maintained by a member of one sex. In the case of polygyny, which is male harem formation, you simply look at the number of females in an average harem.

You can also look it anatomically. If you look at those species that are highly polygynous, in which many females are mated to just one male, we find that they're actually highly sexually dimorphic, and there's a really close one-to-one correspondence between the degree of polygyny in terms of number of mates and the degree of sexual dimorphism.
