Molecules and Mating: Positive Selection and Reproductive Behaviour in Primates

摘要: Sexual reproduction is generally thought to be more costly than asexual reproduction. However, it does have the advantage of accelerating rates adaptation through processes such as recombination and positive selection. Comparative studies human nonhuman primate genomes demonstrated that selection has played an important role in evolutionary history humans other primates. To date, many dozens genes, affected by selection, been identified. In this chapter, we will focus on genes are associated with mating behaviours reproductive processes, concentrating most likely enhance success also show evidence The encode phenotypic features potentially influence mate choice decisions or impact evolution function involved perception regulation of, response to, signals. We consider precopulatory behavioural traits primates, social bonding aggression. post-copulatory strategies sperm competition selective abortion may evolve presence intense these adaptations considered. Although behaviour not solely determined suggests discussed chapter some results degree population differentiation diversity.
