Discovery of Anoles, a class of lizards, questions evolution theory
A study on Anoles, a class of lizards found in the Caribbean islands, has raised doubts over an existing theory of evolution. Evolutionary biologist Kirsten E Nicholson from the Central Michigan University, USA, who studied nearly 140 species of anoles, found that they don't have similar dewlap configurations, even though they are from same microhabitat. In fact, they tend to exhibit different dewlaps, which Nicholson believes, might have evolved through sexual selection. Evolution theory says different animals living in similar habitats evolve to have similar morphology or anatomy.
