Question

Quizplus · Accepted Answer

Homology refers to similarities in structure that are due to common ancestry. The similarities in the bones of the forearms in many vertebrates demonstrate homology, as they are believed to have descended from a common ancestor with this bone structure.

Answer: B and C are not examples of homology.
 The similarities between the Tasmanian wolf and a North American wolf and the similarities between the wings of a bat and the wings of a fly are examples of convergent evolution, which is when unrelated species evolve similar characteristics due to similar environmental pressures. They are not due to common ancestry, so they are not examples of homology.
