[null and void]

Rule of thumb for primates:

Male and female same size = monogamous

Male much larger than female = harems

Humans? Average male just a little larger than average female = mostly monogamous...

;’) Actually, when there’s little in the way of sexual dimorphism (I just like to say it, okay?) i.e., when the genders are the same size, the males often share females (harems, but the other way).
