A Nuer Woman Married to a Woman Can Be the Pater

A Nuer woman married to a woman can be the pater of a child she did not father. Native American berdaches, biological men who represent a third gender, sometimes assume the role of a wife when married to a man with whom they share the products of their labor. Cross-cultural examples such as these illustrate

A) that the concepts of gender and marriage are more socially constructed in some societies than others.
B) how, if they were to be made legal, same-sex marriages could easily benefit from the same legal rights different-sex marriages already enjoy.
C) the rare social phenomenon of polyandry.
D) how same-sex marriages make good economic sense.
E) how Edmund Leach was wrong to suggest that all societies define marriage similarly.
