Discovery News has reported on the recent finding that the endangered tuatara, a lizard-like reptile only found in New Zealand, may be the world's fastest-evolving creature, with a rate of 1.56 changes per nucleotide every million years. The report, published in this month's Trends in Genetics, is particularly surprising given that the animal hasn't changed much physically from its dinosaur-era ancestors, who lived 225 million years ago. The tuatara, whose close ancestors are extinct, is considered a "living fossil."Read the Discover story:
