Anatomical similarities and differences between various organisms allow us to reconstruct and infer evolutionary history and descent.

Which of the following is NOT a reasonable conclusion that can be drawn from the similarities and differences found in this illustration?
Birds, bats, and humans have bones and structures that allow them to function.
Different structures allow for different functions.
Humans live in habitats that are very different from that of birds and bats.
Humans and bats share a closer evolutionary history with each other than with birds.

tetrapod limbs
feathers
amnion
They developed at the same time
