Bats, birds, and humans are vertebrates. Birds and bats have wings that help them fly, and humans don’t have wings. But if you looked at the bone structure of all three organisms, you’d notice similarities in the arrangement of their bones. What can you infer from this information?
A)Birds, bats, and humans share a common ancestor.
B)Birds and bats have evolved from humans.
C)Birds, bats, and humans are mammals.
D)Humans are more related to birds than to bats.
E)Birds are more related to bats than to humans.

Respuesta :

A. They share a common ancestor because otherwise they would not have similar arrangements of bones. It doesn't matter that humans can't fly

The correct answer is A because not all mammals have a similar bone structure, bats and birds have not evolved from us... we evolved from monkeys, humans are actually more related to monkeys rather than bats and birds, and E doesn't really explain anything, but A, 'birds, bats and humans share a common ancestor is correct. It's an accurate answer, it makes sense, and it is true, birds bats and humans do share a common ancestor.
