The forelimbs of vertebrates 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.

What comparative anatomy structure is a result from left over traits that are no longer needed for survival and no longer serve a purpose?

• Analogous Structures

• Homologous Structures

• Vestigial Structures

_____________ Evolution occurs when unrelated organisms evolve traits, structures, or morphologies that carry out the same function. An example is insect flight and bird flight.
