To evaluate the theory, researchers utilized a newly established tool to track the abundance of phosphorus in the oceans hundreds of countless years ago, taped in 6 locations in Australia, China, Mexico, and the US.
The information and Earth chemistry model revealed increasing ocean phosphorus levels could not have described the rise of oxygen. The effect was just reproduced by the model when large quantities of sulfate rock were weathered, launching sulfate into the oceans to produce huge amounts of oxygen.
Lead author and Forrest Fellow Dr. Matthew Dodd, from the UWA School of Earth Sciences, said the outcomes suggested sulfate, rather than phosphorus, was the primary control in the oxygenation of the planet during the very first major development of intricate life.
” Our findings might explain the prolonged low levels of oxygen throughout Earths history and as a result the late development of animal life on Earth,” Dr. Dodd said. “Importantly, we observe that ocean phosphorus was primarily low when oxygen levels were low throughout the Shuram Excursion. This phenomenon would have locked the early oceans and atmosphere into an oxygen-devoid state.”
Data from the research study likewise holds ramifications about the possibility of intelligent life on other worlds.
” These results suggest other potentially habitable worlds might support intricate smart life, just if provided with long sufficient incubation times,” Dr. Dodd stated. “This could suggest worlds around stars bigger than the Sun may not establish complicated intelligent life due to the relatively short life time of big stars.”

A new study suggests that the weathering of sulfate rocks, not increasing ocean phosphorus levels, was essential to the oxygenation of Earths environment, influencing the late advancement of animal life, and likewise shows that potential for intricate smart life on other worlds might need longer incubation times.
A current research study might have discovered a missing link that assists explain Earths distinctively oxygen-saturated environment and the matching development of animal life on our world.
The research study, led by a Fellow of the Forrest Research Foundation at The University of Western Australia and just recently released in the esteemed journal Nature, might hold the key to understanding why, for almost 90% of Earths history, oxygen levels stayed too low for animals to breathe.
The very first significant evolutionary occasion of animal life happened throughout an event dubbed the Shuram Excursion– between 570 and 550 million years back– which is believed to represent an enormous release of carbon dioxide and oxygen into the atmosphere and oceans as an outcome of increasing ocean phosphorus levels.
