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?
One example of evidence that could be used to support the argument that these organisms share an ancestor is patterns in limb structures. If the fossils all have similar limb structures, such as the number of joints or the arrangement of bones within the limbs, it could suggest a common ancestry among the organisms. This similarity in limb structures could indicate that these organisms are part of the same evolutionary lineage that diverged from a common ancestor.
