See, it's perfectly natural Early Human Ancestors May Have Had "Harem" Societies

Some early human ancestors may have lived in "harem" societies much like those of modern gorillas and orangutans, a new fossil study suggests.

Such an arrangement is known to arise in some modern primate species when males mature later in life than females and become much larger than their mates.

The new find is based on analysis of fossils from the human relative Paranthropus robustus.
