[摘要]Sexual reproduction is associated with the evolution of anisogamy　and　sperm-producing males and egg-laying females. The ensuing　competition for mates has led to sexual selection and coevolution of　the sexes. Mathematical models are extensively used to test the plausibility　of different complicated scenarios for the evolution of sexual　traits. Unfortunately, the diversity of models is now itself equally bewildering.　Here we clarify some of the current debate by reviewing　evolutionary explanations for the relationship between anisogamy,　potential reproductive rates, parental care, sex roles, and mate choice.　We review the benefits females might gain by mating with certain　males rather than others.We also consider other forms of selection　that can make females mate nonrandomly. One way empiricists can　contribute to resolving theoretical disputes is to quantify the cost of　expressing mating biases in the appropriate life-history currency.
