Options

  1. AFlippers of penguins and dolphins
  2. BIndustrial melanism in moths
  3. CAntibiotic-resistant bacteria
  4. DDarwin's finches in the Galapagos Islands

Correct answer

D. Darwin's finches in the Galapagos Islands

Step-by-step solution

Adaptive radiation is the process of evolution of different species in a given geographical area starting from a point and radiating to other habitats. A classic example of this phenomenon is Darwin's finches in the Galapagos Islands. Flippers of penguins and dolphins are an example of convergent evolution (analogous structures). Industrial melanism in moths is an example of natural selection. Antibiotic-resistant bacteria represent evolution by anthropogenic action. Answer: Darwin's finches in the Galapagos Island
