Detailed explanation-1: -In theory, male–male competition may aid the process of speciation by sexual selection. First, male–male competition can promote variation in male mating traits and favor divergence in both male traits and the corresponding female mating preferences (van Doorn et al. 2004).

Detailed explanation-2: -Intersexual selection occurs when one sex chooses which members of the opposite sex to mate with, while intrasexual selection occurs when members of the same sex compete for mates (Darwin 1871). In many species, males compete through intrasexual competition to gain access to females.
