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

• heights
• number of bones
• patterns in limb structures
• tooth features

Answer 1

A potential 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 exhibit similar patterns in the structures of their limbs, such as having the same arrangement of bones or similar joint locations, it suggests a common ancestry. This can indicate that they inherited these limb structures from a shared ancestor and subsequently evolved in different ways.
