Original article on LiveScience.As a part of breeding starfish. These developments gave rise to the first carnivores and marked beginning of the marine biosphere that looks familiar today.įollow Megan Gannon on Twitter and Google+. This new abundance of oxygen may have provided fledgling animals the extra power to gain greater mobility and evolve complex body forms like guts during the Cambrian explosion, the period about a half a billion years ago that saw a burst of evolutionary changes in life on Earth. This would have lowered overall biological productivity and freed up even more oxygen in the water, creating a feedback loop. As sponges put oxygen back into the water, less phosphorous - a key biological nutrient - could be released in the ocean. Sponges may have helped put even more oxygen into the oceans in an indirect way, the researchers say. This feeding process puts more oxygen back into the environment. Instead, they eat by filtering water through their bodies and taking out organic matter from the water column.
