[10e] Name this evolutionary process in which a population splits into two groups that can no longer breed.
ANSWER: speciation
[10h] A species of blind cichlids living in the Congo underwent this phenomenon. This phenomenon is the major driving force of evolution according to Kimura’s neutral theory..
ANSWER: genetic drift [accept bottleneck effect or population bottleneck]
[10m] Cichlids in Lake Victoria underwent this process. This process, which was observed in Darwin’s finches, involves a common ancestor rapidly diversifying into multiple species which occupy available niches.
ANSWER: adaptive radiation [prompt on radiation or evolutionary radiation]
