Sexual Selection: Male-Male Competition
Aggression. Offensive action, particularly in regard to defending resources. Aggression in defending females and other resources should be favored by selection when there are fewer resources than competitors and when an individual can boost fitness by forcibly removing another individual. Intersexual Selection. Sexual selection due to interactions between the sexes. Mate choice by males or fema...
متن کاملSexual Selection, Social Competition, and Evolution*
Social behavior holds a special position among natural phenomena in relation to the Darwinian theory of organic evolution. When individuals of the same species live in close proximity they compete directly for essential resources. And intraspecific reproductive competition is the cornerstone of the theory of evolution by natural selection. Thus the drama of what G. E. Hutchinson (1965) referred...
متن کاملFemale remating, sperm competition and sexual selection in Drosophila.
Female remating is fundamental to evolutionary biology as it determines the pattern of sexual selection and sexual conflict. Remating in females is an important component of Drosophila mating systems because it affects sperm usage patterns and sexual selection. Remating is common in females of many species of Drosophila in both natural and laboratory populations. It has been reported in many in...

متن کاملSexual selection fails to promote adaptation to a new environment.
Selection can be divided into sexual and nonsexual components. Some work finds that a component of sexual selection, adaptive female selection for good genes, can promote nonsexual fitness. Less studied is the benefit from sexual selection in toto, that is, when intra- and intersexual selection are both present and able to affect females directly and indirectly. Here an upper bound for the net ...
