The Speedy Gonzales of genetic evolution

"Now toss into this mess the recent discovery that some species 'evolve' genetically while remaining unchanged anatomically. Scientists at Massey University in New Zealand have found that a reptile called the tuatara differs genetically from its 8,000-year-old ancestors, while retaining the same anatomical makeup and outward appearance. The tuatara’s DNA changes make it the Speedy Gonzales of genetic evolution. According to Axel Meyer of Germany’s University of Konstanz, the discovery suggests 'a real disconnect' can exist between genetic and anatomical evolution."
