The image below compares the structure of a bat wing to that of a bird. Based on what you know about the classifications of these animals and the difference in the bone structure of their wings, which of the following is the most logical conclusion about their evolution?

Bat and bird wing bones and silhouettes are shown side-by-side. Each has a single 'upper arm' bone and two parallel 'lower arm' bones that attach to 'hand' bones. The bat wing has 4 long digits inside the wing and one outside the wing. The bird has three digits inside the wing. The bat wing's silhouette has skin stretched between the digits while the bird wing's silhouette has feathery edges.

They both descended from a recent common ancestor, making bats more closely related to birds than to other mammals.
They both inherited their wings from a common ancestor and then diverged in their other body characteristics.
They evolved from a wingless common ancestor and developed wings independent of each other.
They evolved from entirely different ancestors, but both developed wings in response to similar ecological conditions.

Answer:

They evolved from entirely different ancestors, but both developed wings in response to similar ecological conditions.

Explanation:

Based on the info given, they possibly could have had the same ancestor, but even if that was true, the bat would have some type of resemblance other than wings. I think that due to environmental changes, natural selection allowed these organisms to fly so they can survive in that environment. Birds got feathers because they could have been in a cold ecosystem so they needed warmth for themselves and their young as well as stay away from predators, due to their small size they had no way to get away without wings. They didn't have legs for running so they developed wings. Bats may have been in a fine temperature, but the day caused problems due to hunting, so they developed wings to hunt at night and keep themselves in caves to hide from predators.

This is the best I could do, I hope this helped :)

Based on evolutionary relationships, they evolved from entirely different ancestors, but both evolved wings in response to similar ecological conditions.

What is the logical conclusion about the evolution od bats and birds?

Bats are mammals in that have mammary glands and they give birth to their young alive. Bats have fur on covering their skin

Birds are not mammals as they do not have mammary glands and do not give birth to their young alive. Birds are classified as aves and have feathers covering their skin.

Comparing the wings of bats and birds shows that even though the are functionally analogous, they are different. It is an example of convergent evolution.

Therefore, the best conclusion will be that they evolved from entirely different ancestors, but both developed wings in response to similar ecological conditions.
