Question

bat wings, human forelimbs, and whale flippers are known as homologous structures, meaning they are all comparatively similar in that they contain most of the same bones in a similar configuration, even if they are used for different functions. of the following, which best describes how homologous structures are evidence for evolution? a. homologous structures provide evidence that forelimbs have evolved. b. homologous structures provide evidence for nonsense mutations. c. homologous structures provide evidence of common ancestry. d. homologous structures provide evidence that forelimbs have not evolved.

Explanation:

Homologous structures are similar in structure because they are inherited from a common ancestor. They can have different functions in different organisms, and this provides evidence of common ancestry. For example, the forelimbs of humans, whales, and bats have a similar bone - structure despite their different uses (grasping, swimming, flying). This shows that these organisms share a common ancestor from which they inherited this forelimb structure.

Answer:

B. Homologous structures provide evidence of common ancestry.
