Jonathan Losos and colleagues conducted experiments on small, hurricane-swept islands as "natural laboratories." Which of the following statements is true?
Select all that apply.

A] Experiments on the small islands show evidence for adaptation by natural selection but not for evolution.
B] The legs of the anoles placed on the islands became shorter, and their offspring inherited shorter legs.
C] Islands scrubbed by hurricanes allow researchers to introduce new lizard populations and observe their evolution.
D] There are many small islands with similar environments, meaning that researchers can repeat their experiments and observations in several locations.
E] Natural selection can lead to rapid changes. The average leg length of lizard populations decreased within a few generations.
