Surge in oxygen levels led to explosion of life on earth: Study

According to recently published study, boost in levels of oxygen may have caused three-fold increase in biodiversity (or biodiversification) during between 445 and 485 million years ago. The study was conducted using geochemical proxies, high-resolution data and chemical signatures preserved in carbonate rocks formed from seawater. Using it, researchers were able to identify oxygen increase ..
