The Earth's ancient oceans had much lower content of sulfate than previously thought, a new study has said. The findings paint a new portrait of our planet's early biosphere and primitive marine life. Organisms require sulfur as a nutrient, and it plays a central role in regulating atmospheric chemistry and global climate. Measuring these fingerprints in rocks older than 2.5 billion years, they discovered sulfate 80 times lower than previously thought. ...Sunday 9 November 2014
