PLEASE HELP! Examine these two images. Then answer the questions that follow.

Image A is a comparison of the bone structure of humans and four living organisms. Image B compares the skulls of three different organisms. The opening in the skulls is called the foramen magnum. This opening supports the spinal cord and is related to posture and movement in organisms. Whether an organism can walk on two legs or four legs can be predicted based on the location of the foramen magnum.

Part A

What similarities and differences exist in the body parts shown in image A? In your answer, evaluate the anatomy and mention the part’s function in the respective organisms.

Part B

What do you think image A says about the evolution of these organisms?

Part C

Image B depicts three skulls. Do you think the image supports the fact that all three organisms share an evolutionary relationship? Explain your answer using evidence from the image.

Part D

Do you think image B supports the idea that some vertebrates are more closely related than others? Explain your answers with reasons.
