Crucially, the first tetrapods descended from lobe-finned, rather than ray ... Evolution of fish. The Devonian period 419–359 Ma (Age of Fishes) saw the development of early sharks, armoured placoderms and various lobe-finned fishes including the tetrapod transitional species. The evolution of fish began about 530 million years ago during the Cambrian explosion.
New studies reveal the ancient, shared genetic “grammar” underpinning the diverse evolution of fish fins and tetrapod limbs.
