Life thrived in the oceans because the deep water filtered out the most harmful wavelengths of light. Deep underwater, blue and green light dominated. How did this fact influence the appearance of early plants?
Living off the colors of light available to them, bacteria in deeper water were green. Over time, these green bacteria grew to dominate the oceans and are considered early ancestors of today’s plants.
