Detailed explanation-1: -Speciation is the process by which new species form. It occurs when groups in a species become reproductively isolated and diverge. In allopatric speciation, groups from an ancestral population evolve into separate species due to a period of geographical separation.

Detailed explanation-2: -New species are formed when its members are no longer able to reproduce with members of the parent species. The commonly-accepted mechanism is called allopatric speciation, in which geographic barriers-such as mountains-separate members of a group, causing them to evolve independently.

Detailed explanation-3: -Speciation is an evolutionary process by which a new species comes into being. A species is a group of organisms that can reproduce with one another to produce fertile offspring and is reproductively isolated from other organisms.

Detailed explanation-4: -Sympatric speciation: the new species evolves within the geographic range of its ancestor.

Detailed explanation-5: -An example of peripatric speciation occurred with the London Underground mosquito. This species broke off from the main species to the London Underground. They have different behaviours and can breed all year round unlike its ancestor species which hibernates in winter.
