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
1 answer
One example of evidence that could support the argument that these organisms share a common ancestor is the presence of homologous structures among the fossils. Homologous structures are similar structures found in different organisms that are inherited from a common ancestor. By comparing the similarities in structure and function of certain body parts among the fossilized organisms, you could make the case that they are all related through a shared evolutionary history. This shared ancestry would suggest that despite the differences in appearance, these organisms are actually part of the same evolutionary lineage.
