Darwin's explanation for evolution was dependent on which scientific concept?

• The significance of social behaviors to survival
• The existence of variations in a population

The forelimbs of vertebrates, like the ones pictured here, are similar in terms of number of bones and the orientation of bones. Which best describes how comparing homologous structures provides evidence of evolution?

• The genes for the body plan and forelimb layout were present in a common ancestral species vertebrates share, thus passed onto all vertebrates.
• Similar anatomical structures show how animals adapt to changing environments
• Homologous structures show that different species evolve at different rates
• Homologous structures don’t actually provide evidence for evolution
