Answer;
D. They are evidence that the animals had a common ancestor.
Explanation;
- Homologous structure are structures that are similar in different species of common ancestry. Dolphin's flipper, bird's wing, cat's leg, and the human arm are considered homologous structures demonstrating that these creatures all had a common ancestor.
- Analogous structures on the other hand are body parts that share a common function but not structure. For example; walking limbs of insects and vertebrates.
- Therefore; homologous structures provide evidence for evolution because it shows the similarities and how organisms evolved from the same ancestors
