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.

Question

the highlighted yellow is ulna in the human body, cat, body, whale body, and bat body
Whether these structures are homologous or analogous
An explanation of how these structures provide evidence for evolution
Your answer should be 2 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.

Answer 1

The highlighted structures are homologous, meaning they are derived from a common ancestor, as evidenced by the similar bone structures (like the ulna) found in diverse species such as humans, cats, whales, and bats. This similarity in anatomy provides evidence for evolution by demonstrating the shared evolutionary history among these organisms, reflecting how different adaptations arose from a common skeletal framework.
