Answer:
Allopatric speciation- speciation in different places.
Explanation:
This is the process by which two populations of organisms of the same species in the same habitats are geographically isolated or separated from one another, by natural means,(floods, earthquakes,).
The selective pressures in their two new habitats acted on them for long time to the extent that their physiological,(body functions) morphological( body structures) and behavioural characteristics changed making them to emerged as new species.
If these two populations meets after years they will find it difficult to interbreed. Therefore the type of speciation which emerged through a Geographical isolation like this is called ALLOPATRIC SPECIATION.
