How can isolation help in speciation?
Answer and explanation
Correct answer: By accumulating different changes in groups
The governing concept is reproductive or geographical isolation in speciation. When members of one population become separated, the groups may face different climates, foods, predators, or other conditions. Mutations, inherited variations, and natural selection can then produce different changes in each group. Over many generations, the groups may become sufficiently different to form separate species. Thus option A is correct; the other choices do not describe speciation.
