Salvador Rivera · Answer 1

A remarkable number of species on an island that are found nowhere else is a result of island isolation that promotes allopatric speciation where there is an evolution of species caused by the geographic isolation of two or more populations of a species. These results to increase biodiversity of species found on the island.

Patricia Wade · Answer 2

Island isolation promotes allopatric speciation. Species are separated by the physical barrier which is in the ocean and islands are being isolated by each other by bodies of water.

There is no gene flow which occurs between the separated species. Living in the distinct island. The species get adopted by the island to the environment.

They then diverge as they separate species.
