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?

Question

(1 point)
• heights
• number of bones
• patterns in limb structures
• tooth features

Answer 1

The best evidence that could be used to support the argument that these organisms share an ancestor is patterns in limb structures. Similarities in limb structures across different organisms, despite differences in other features, suggest a common ancestor with similar limb structures that have been modified over time.
