Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Humans built a 6-lane highway that separated two populations of field mice. There is enough distance between the two groups, that they will never meet in nature again. What type of reproductive isolation is this?
A
behavioral isolation
B
temporal isolation
C
geographic isolation
Explanation: 

Detailed explanation-1: -Speciation is the process by which new species form. It occurs when groups in a species become reproductively isolated and diverge. In allopatric speciation, groups from an ancestral population evolve into separate species due to a period of geographical separation.

Detailed explanation-2: -Behavioral isolation occurs when two populations that are capable of interbreeding develop differences in courtship rituals or other behaviors.

Detailed explanation-3: -Speciation occurs when a group within a species separates from other members of its species and develops its own unique characteristics. The demands of a different environment or the characteristics of the members of the new group will differentiate the new species from their ancestors.

Detailed explanation-4: -Geographical Isolation (allopatry) The proximity of the various islands has permitted enough migration of Darwin’s finches between them to enable distinct island populations to arise. But the distances between the islands is great enough to limit interbreeding between populations on different islands.
