Ancient ocean phosphorus cycles reveal Earth's 2.3-billion-year oxygen secret

Phosphorus recycling in ancient oceans may have solved a 2.3-billion-year mystery: how Earth kept enough oxygen to support life. New evidence from old rocks reveals a self-sustaining cycle that maintained high oxygen levels through dramatic planetary change. This challenges long-held assumptions about our early atmosphere. It also raises compelling questions about why complex life took so long to emerge. For deeper context, our coverage of "Acidification Alters Phytoplankton Chemistry" explores how ocean chemistry continues shaping life today.
