Mar 22, 2020 · The jawed fish (the Gnathosomes) who were eventually to replace them in the world’s waters – and later to give rise to the rest of the vertebrates – were already appearing as early as 425 MYA. The arising of moveable, skeletally supported jaws was a most important step in the evolution of modern fish and thus in the evolution of mankind.
