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 support the argument that the different organisms share an ancestor is the presence of homologous structures. Homologous structures are similar structures in different organisms that have a common ancestry, and this similarity could suggest that the organisms share a common ancestor. For instance, if you and your friend found that some of the fossils had similar bone structures in their limbs, this could suggest that those organisms were related through a common ancestor, even if they had different overall appearances. This type of evidence would indicate that the organisms share a common evolutionary lineage, rather than simply appearing to be unrelated due to differences in their external features.
