In studying anoles, Rosario Castaneda is looking at how animals evolve. There are more than 380 species of the lizards in the Americas, and diversity among them is incredible. Some are big, some are small; they're all evolved to fit their own habitat.
Creativity is hard to define. And Gary Marcus of New York University says its equally hard to measure. He says creativity is different in each individual.
