Question

cardueline finches can be found in many areas of the world, including north america and asia. hawaiian honeycreepers, which are found only in hawaii, have been found to have dna commonalities with this group of finches that indicate they have a common ancestor. which mechanism might have led to the appearance of the hawaiian honeycreeper?
o anatomical isolation
o temporal isolation
o geographical isolation
o behavioral isolation

Explanation:

Geographical isolation occurs when a population is separated by a physical barrier like an ocean. Hawaiian honeycreepers are found only in Hawaii, separated from cardueline finches in other parts of the world by vast distances of water. This isolation can lead to the development of new species through genetic divergence over time. Anatomical isolation refers to physical differences in body - parts that prevent mating; temporal isolation is about differences in breeding times; and behavioral isolation is about differences in courtship or other behaviors. None of these are indicated as the cause here as much as the geographical separation.

Answer:

C. geographical isolation
