During Hurricane Marilyn 15 green iguanas were blown out to

During Hurricane Marilyn, 15 green iguanas were blown out to sea from the island of Guadalupe. They floated on mats of vegetation for several weeks until they landed on the island of Anguilla. If these green iguanas evolve reproductive barriers and become a new species, this would be an example of:

A. allopatric speciation

B. sympatric speciation

C. postzygotic barrier

D. a miracle

E. none of the above

Solution

A) Allopatric speciation

This is also known as geographic speciation. This occurs when the same biological species are separated or isolated from each other , that it would result in reproductive barriers, preventing them from exchanging genetic material . These are also said to be isolated from each other or vicariant.
