The Evolution of Hammerhead Sharks

Sharks have had a place in the ecosystems of the ocean for over 400 million years, being present in the sea long before dinosaurs existed, before trees existed, and sharks are in fact roughly as old as terrestrial plants. Over this very vast amount of time It is often thought that sharks have stopped evolving or remained unchanged for many years. However, in there long history they have adapted many new forms and they continue to evolve to this day. And no group of sharks shows this more than the hammerhead sharks. So why did they evolve their famous head shapes.
