Geographical Isolation explain briefly
Answers
Geographical isolation means separation of species by physical barriers like water forms, oceans, mountains etc. ... As there are less chances for variations to oocur, new species are not formed in asexually reproducing individuals undergoing geographic isolation.
Speciation refers to the formation of a new, distinct species from the main population of a particular organism mainly due to genetic incompatibility. The geographical isolation is the physical separation of two populations by the geographical barriers. This occurs through adaptive radiation and allopatric speciation.
When this happens, populations of organisms can become isolated. Geographic isolation is the separation of a population of organisms from the rest of its species due to some physical barrier, such as a mountain range or an ocean.
