With reference to evolution of organisms, which of the following options CORRECTLY matches the example with the related type of structure and the type of evolution?
Correct answer: B. Wings of bats and arms of monkeys, homologous, divergent evolution
- A. Wings of insects and birds, homologous, convergent evolution
- B. Wings of bats and arms of monkeys, homologous, divergent evolution
- C. Wings of bats and arms of monkeys, analogous, convergent evolution
- D. Wings of insects and birds, analogous, divergent evolution
Explanation
The correct answer is Option B. Homologous structures, like the wings of bats and arms of monkeys, arise from a common ancestor and display divergent evolution as they adapt to different environments and functions. Option A is incorrect because the wings of insects and birds are analogous, not homologous, and result from convergent evolution. Option C is incorrect as it mislabels the structures as analogous and the process as convergent. Option D is incorrect because it incorrectly attributes divergent evolution to analogous structures.

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.
