Rare pink iguana helps define history of Galapagos Islands

A rare kind of iguana with pink skin, the rosada iguana, that lives only on the Galapagos Islands, diverged from other iguana species on the island more than five million years ago, according to findings reported in the Proceedings of the National Academy of Sciences. One of the oldest examples of divergence on the island, the researchers believed that the pink iguanas began to evolve separately from other iguanas while the island was still forming.
