Jonathan Losos and colleagues conducted experiments on small, hurricane-swept islands as “natural laboratories.” Which of the following statements is true?   The legs of the anoles placed on the islands became shorter, and their offspring inherited shorter legs. Experiments on the small islands show evidence for adaptation by natural selection but not for evolution. Natural selection can lead to rapid changes. The average leg length of lizard populations decreased within a few generations. Islands scrubbed by hurricanes allow researchers to introduce new lizard populations and observe their evolution. There are many small islands with similar environments, meaning that researchers can repeat their experiments and observations in several locations.

Marine Evolution

Marine habitat is less explored, and hence, its biological diversity is far less known. The marine habitats are not constant due to their shifting nature, while the terrestrial habitats are more stable. Marine biology is the science that deals with the study of diverse marine species, their interactions, and behavioral characteristics.
