Evidence from molecular biology supports the theory of evolution by demonstrating that __________.

• A. homologous proteins have arisen independently in many different animal groups
• B. closely related animal species have similar geographic distributions
• C. closely related organisms have similar stages of development
• D. None of the listed responses is correct.
• E. closely related organisms have more similar DNA and proteins than more distantly related organisms

Answer: (E)

Verified step by step guidance

1. Understand that molecular biology provides evidence for evolution by comparing DNA and protein sequences among different organisms.
2. Recognize that closely related organisms share a more recent common ancestor, which is reflected in their genetic material.
3. Consider that DNA and proteins evolve over time, and the degree of similarity in these molecules can indicate how closely related two species are.
4. Note that homologous proteins and DNA sequences are more similar in closely related species than in those that are distantly related.
5. Conclude that the similarity in DNA and protein sequences among closely related organisms supports the theory of evolution by showing common ancestry.
