Question:

The similarity of bone structure in the forelimbs of many vertebrates is an example of: Convergent evolution, Homology, Adaptive radiation, Analogy?

Convergent evolution

Adaptive radiation

Analogy

Homology

Solution:

The bones in the forelimbs of the vertebrates are having a common arrangement. They have the same pattern of bones which shows that this pattern is from a common ancestor. However, their forelimbs now have different functions. This is the criteria for homologous organs. Thus, the correct answer is option B.
