Quizplus · Accepted Answer

The forelimb bones of vertebrates are one of the classic examples of homologous structures, meaning they can be traced back to a common ancestor. This supports the theory of evolution, as it suggests that different species have evolved from a common ancestor, with some features being conserved over time.
