Speciation is the evolutionary process by which biological populations evolve to become distinct species. The biologist Orator F. Cook coined the term 'speciation' in 1906 for the splitting of lineages or cladogenesis, as opposed to anagenesis or phyletic evolution within lineages.
Parapatric speciation is the culmination of this unequal gene flow effect, in which genotypic dimorphism between populations results in speciation of the population and redefines the population as two or more sister species.arapatric speciation may be associated with differential landscape-dependent selection. Even if there is a gene flow between two populations, strong differential selection may impede assimilation and different species may eventually develop.
