common ancestry

Why is it important to study both living and extinct species in evolutionary biology?

• Extinct species are more interesting than living ones.
• Studying both reveals similarities and differences that provide evidence of evolution.
• Living species are irrelevant to understanding evolution.
• Only extinct species provide evidence of evolution.

How do homologous structures provide insight into evolutionary relationships?

• They reveal similarities in body parts that suggest common ancestry.
• They indicate that species have evolved independently.
• They show that different species have completely different body plans.
• They are only found in vertebrates.

How does DNA sequencing contribute to our understanding of evolutionary relationships?

• It shows the physical characteristics of extinct species.
• It allows researchers to determine the age of fossils.
• It provides evidence that evolution does not occur.
• It helps identify how closely related different species are.
