White Lizards Evolve in New Mexico Dunes

Deep in the White Sands of New Mexico, for the past decade, scientists have been doing research on these lizards that were brown, but over time became white. Professor Erica Bree Rosenbloom, from the University of Idaho says that brown lizards very rare and hard to find. Her focus is on three lizard species that have supposedly turned white so they can hide or escape from their predators. This is an example of convergent evolution, when all species aquire the same traits. But despite this the fact that they all have the same traits, the mutations and molecular mechanism is different, and the mutation has made the white skin trait dominant, and the trait spreads more quickly through the first species of Lizards than it does the rest. This article is very captivating and informative of the tough subject of evolution. It makes me think about all the experiments people will be doing on animals to test the theory of evolution, and how creatures adapt to new environments which some how can change their physical appearances that make them look somewhat abnormal.
