Examine the image below. Notice how all organisms in the image share several of the same bones (highlighted in orange and yellow). Are these homologous structures (homologies) or analogous structures(analogies)? Explain how these structures provide evidence for evolution and the relationship among organisms.
Grading Considerations
Your answer must include:
Whether these structures are homologous or analogous
An explanation of how these structures provide evidence for evolution
Your answer should be 2-4 sentences in length. In an effort to combat plagiarism, answers longer than 5 sentences will not be considered. Answering concisely and to the point is evidence of your understanding of the topic.

These structures are homologous because they share a common evolutionary origin. The presence of these shared bones among different organisms indicates a shared ancestry and evolutionary relationship. This supports the theory of evolution by demonstrating how species have descended from a common ancestor and have diverged over time to develop unique characteristics.
