  • A. fishes tail fin
  • B. dog's front legs

Explanation

Homologous Organs: These organs have similar anatomical structures but perform different functions. They are the result of divergent evolution. A human's arm, a dog's leg, a bird's wing, and a whale's flipper are all homologous. The same bones are found in each structure; they only differ in their size and shape.

About Concept of Evolution

Evolution is the heritable change in populations over generations, driven by mutation, recombination, natural selection, genetic drift and reproductive isolation. Questions examine variation, adaptation, survival and reproduction, speciation, fossil and anatomical evidence, and the difference between individual acclimatization and evolutionary change in a population.
