The Evolution of Mammalian Sociality by Sexual Selection

摘要: This chapter addresses the evolution of mammalian sociality by sexual selection (“intrasexual” and “intersexual” selection), a topic directly related to actions available types maximizing “inclusive fitness.” As females are “energy-maximizers,” spatiotemporal distributions may entail significant (relative) fitness costs that males, “time-minimizers,” not be in position afford. Energy-saving strategies also indicated for female mammals due their high “reproductive load” vulnerability effects offspring competition. Energy savings is thermal regulatory process defining natural selection, maintaining usable heat within limits propitious optimal functioning (maintenance, growth, survival, reproduction). Thus, traits drive male traits. Studies using Drosophila melanogaster as subjects showed “sexual conflict” arises because “promiscuity” incompatible with mutual interests, finding direct import since promiscuity have been initial state tolerance from which evolved, linking sociosexual assemblages class.
