You and your friend inspect a group of fossils from different organisms with various features. Your friend is convinced that all of the fossils are unrelated, but you find evidence that these organisms share an ancestor. What is an example of evidence that you could use to best support this argument?

A. heights
B. patterns on limb structures
C. tooth features
D. Number of bones

B. patterns on limb structures

By comparing the patterns on limb structures of the different organisms in the fossils, you can identify similarities that indicate a shared ancestor. For example, if the fossils show similar bone structures in the limbs, it suggests a common ancestry despite the organisms having different overall features. This evidence would support the argument that the organisms are related.
