18 Societies in sub-Saharan Africa and the Caribbean are much more polygynous than the Muslim nations in the Middle East and North Africa.

19 Typically, human males are 10 percent taller and 20 percent heavier than females.This suggests that, throughout history, humans have been mildly polygynous.

20 We apply the Trivers-Willard prediction - that mothers in poor condition will overproduce daughters - to a novel measure of condition, namely wife rank within a polygynous marriage.

21 Mothers in poor condition, here lower-ranking co-wives in a polygynous marriage, may overproduce daughters because these give them greater fitness returns than sons.
