If the bodies of present-day bats became fossilized over time, which observation would future scientists likely make about the wings of rossilized bats and pterosaurs?

Question

Both sets of fossils would show similar structures and bone material that were suited for flight.
The bat wing bones would show a completely different sulcture than the pterosaur bones.
A comparison of the bones of both organisms would show that the pterosaurs were better suited for flight than bats were.
Both sets of fossils would show that the animals were not designed for lengthy, sustained flight.

Answer 1

If the bodies of present-day bats became fossilized over time, future scientists would likely make the observation that both sets of fossils would show similar structures and bone material that were suited for flight.

Bats and pterosaurs are examples of convergent evolution, where different organisms develop similar adaptations (in this case, wings) to perform similar functions (in this case, flight), despite their different evolutionary backgrounds. While the bone structures would differ in specifics due to their separate lineages (mammals vs. reptiles), the adaptations for flight would exhibit comparable modifications suited for their environments and lifestyles.
