They use their limbs for different functions.

They have evolved from a common ancestor.

Their bone structures have not changed over time.

Their bone structures were more complex in the past.

Answer 1

Answer:

B. They have evolved from a common ancestor

Explanation:

Answer 2

The correct answer is B) They have evolved from a common ancestor.

Based on the diagram, the statement that is correct about birds, bats, and humans is "They have evolved from a common ancestor."

In scientific terms, we could say that the bat, the bird, and humans have homologous structures. This means that limbs have similar bone structures like the ones shown in the picture. Being the anatomy so similar, scientist concludes that some animals descend from the same ancestor in the process of evolution. So if we trace back these ancestors, we could find that we have similar origins.
