Over many generations, natural selection favors those traits that enable populations to live successfully in a particular habitat. A scientist
discovered two species of anole lizards that live in different habitats and
display the characteristics listed in the table below. (The scientists based
these observations on a sample of 20 lizards from each species.) a.
Describe two differences between the two species of anoles. b.
Formulate two hypotheses to explain why each of these differences may
have evolved.
