Solution

Evolution of species is known as speciation . Speciation is the formation of new and distinct species in the course of evolution. Speciation involves the splitting of a single evolutionary lineage into two or more genetically independent lineage and it has four types namely allopatric, peripatric, parapatric and sympatric.
In allopatric , the population of species split into two geographical population due to change in their geography.
In peripetric new species are formed and they are prevented from exchanging genes with the main population.
Parapatric individuals of each species cross-habitat from time to time.
In sympatric there is the formation of more species from a single ancestral species.
