What animals are evolving the fastest?

New Zealand’s ‘Living Dinosaur’ — The Tuatara — Is Surprisingly The Fastest Evolving Animal.

What is the order of evolution?

These are the Hadean (4.6 billion to 4 billion years ago), the Archean (4 billion to 2.5 billion years ago), the Proterozoic (2.5 billion to 541 million years ago), and the Phanerozoic (541 million years ago to the present).
