Sluggish tuatara fastest in DNA evolution
They are slow to grow, slow to reproduce and have a sluggish metabolism.

But tuatara have broken records for DNA evolution, a discovery that has astonished New Zealand scientists.

Tuatara, often referred to as living dinosaurs, have largely not changed physically over very long periods of evolution going back millions of years.

But analysis of their old bones in New Zealand has shown that their DNA has evolved faster than any other animal species yet studied.

1. Tuatuaras are *not* refered to as "living dinosaurs"
Sometimes living fossils, but not living dinosaurs. They're at the base of the lizard-snake group.
