Between 700-550 million years ago, in the late Proterozoic, oxygen levels in the oceans and atmosphere increased dramatically. By 600 million years ago, the oxygen in the atmosphere reached about one-fifth of today’s level (21 percent). The oxygen boom favored the evolution of lifeforms that could use oxygen to create energy.
