[Campbell Biology P.607] According to the text, which of the following is a strong clue for ... | Practice Question

According to the text, which of the following is a strong clue for distinguishing between homology and analogy when comparing complex structures?

  • A: The overall size of the structures.
  • B: The presence of identical, intricate details in the structures, such as the perfect match of bones in human and chimpanzee skulls.
  • C: The difference in the environmental pressures faced by the organisms.
  • D: The rate at which the structures evolved over time.
  • E: Whether the structures are used for the same function.

Explanation

The text states that 'the more elements that are similar in two complex structures, the more likely it is that the structures evolved from a common ancestor.' It provides the example of human and chimpanzee skulls, which 'match almost perfectly, bone for bone,' as strong evidence for homology.
