Rare pink iguana studied

A species of pink land iguana overlooked by Charles Darwin during his visits to the Galapagos Islands may provide evidence of the ancient animals' diversification in the archipelago, scientists have reported. Galapagos National Park rangers first stumbled upon the striking land lizard a few decades ago, but this week's study in the Proceedings of the National Academy of Sciences is the first to officially document the iguana.
