Detailed explanation-1: -Speciation is the process by which new species form. It occurs when groups in a species become reproductively isolated and diverge.

Detailed explanation-2: -When populations become reproductively isolated, they can evolve into two separate species. Reproductive isolation can develop in a variety of ways, including behavioral isolation, geographic isolation, and temporal isolation. Speciation is the formation of a new species.

Detailed explanation-3: -Sympatric speciation, from the Greek ‘same place’, involves the splitting of an ancestral species into two or more reproductively isolated groups without geographical isolation of those groups.

Detailed explanation-4: -They result from natural selection, sexual selection, or even genetic drift: The evolution of different mating location, mating time, or mating rituals: Genetically-based changes to these aspects of mating could complete the process of reproductive isolation and speciation.
