Explanation of Solution
Adaptive radiation is an important concept in evolutionary biology. The adaptive radiation is one of the few processes that allow the divergence or convergence of two or more species. Adaptive radiation requires both allopatric and sympatric speciation along with adaptation to different habitats. Speciation mainly occurs allopatrically and leads to rising of species that colonize other islands producing multiple species per island.
To determine: The relationship between the sympatric speciation and character displacement.
Introduction: Evolution of organism results into various types of accumulations in the genes of an organism that enable an individual to adapt in the changing environment.
Explanation of Solution
Sympatric speciation also occurs during the course of multiple generation because of disruptive selection and can result in the population to contain individuals exhibiting two different phenotypes. The instantaneous sympatric speciation occurs when an individual born is reproductively isolated from all other members of its species. A mutation that would cause an individual to be different from other members of species result in pleiotropic effects and subsequently end in adaptive radiation.
