1981) Monogamous mammalian species exhibit a variety of life histories Not a single ecological mechanism could fully explain the occurrence of monogamy in all mammalian species However, a list of characteristics has been proposed (Kleiman, 1977; Carter and Getz, 1993; Carter et al , 1995) to determine if monogamy occurred In a population with
- Male Infanticide leads to social monogamy in primates
A number of hypotheses have been proposed to explain the evolution of social monogamy among mammals: as a male mate-guarding strategy, because of the benefits of bi-parental care, or as a defense
