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 point)

Answer 1

The best evidence to support the argument that the organisms share an ancestor is patterns in limb structures. Similarities in limb structures among different organisms (such as the bone arrangement in the forelimbs of mammals, birds, and reptiles) can indicate a common ancestry, as they suggest that these organisms have evolved from a shared ancestor over time, adapting their limb structures for different functions while maintaining a fundamental structural similarity.
