One of the very first evolutionary theories regarding the polygyny are help with by Herbert Spencer (1876; see Carneiro 1967: xliii; M. Ember 1974; M. Ember, Ember, and Low 2007) just who suggested one societies sense highest loss of men existence inside the warfare will have higher reproductive victory if they skilled polygyny compared having communities which had a leading death of men lifestyle however, went on to practice monogamy.
