What is geographical isolation??....
Answers
Answer:
The separation of two populations of the same species or breeding group by a physical barrier, such as a mountain or body of water. Geographical isolation may ultimately lead to the populations becoming separate species by adaptive radiation. See also allopatric; speciation.

Answer:
When two populations of the same species are prevented from mating by a barrier or distance, they are experiencing geographic isolation.
Barriers can be created by changing environments, like shifting mountains and rivers. They can also be produced by natural disasters, like forest fires, earthquakes, and floods.
Isolation stops the exchange of genetic material between the two populations. They start to evolve separately from each other because their environments are different. Differences in climate and food sources can create selective pressures unique to each population. Eventually, the two populations might become different species, but not always.
