The youngest species might've evolved less than 2 million years ago. And by evolutionary standards, that's recent -- and a major contradiction to the widely held belief that sharks are slow to evolve.
"The discovery proves that modern sharks have remarkable evolutionary staying power and the ability to adapt to environmental changes," said Mark Erdmann, the paper's co-author and Conservation International Vice President of Asia-Pacific marine programs.
Sharks are older than dinosaurs, dominating the seas for as long as 400 million years (the oldest dinosaur fossil is thought to be about 240 million years old, by comparison). So the fact that sharks continue to evolve as recently as 399 million years later is pretty remarkable.
