The bones of the forelimbs (wing or arm) of three animals are shown in the illustration. What is the most reasonable conclusion that can be drawn from a comparison of these structures?

• Birds and bats are closely related to each other while humans are unrelated to both

• The common ancestor of birds and bats must have had wings and flown.

• Humans live in habitats very different from the habitats of both birds and bats.

• Humans and bats share a closer evolutionary history with each other than with birds.
