DescriptionMarine productivity relies on a constant flux of essential nutrients in order to fix CO2 and produce O2. Phosphorous, is considered to be a primary limiting nutrient for life. The element is supplied via the continental weathering of silicate rocks - a process which is thought to have been limited by reduced continental exposure during the Archean Eon (4 -2.5 Ga). A lack of consistent P supply would have heavily constrained productivity and the development of the nascent biosphere without recycling. Here, we show that under putative Archean conditions (anoxic, Fe2+ rich), UV light quickly degrades biologically ubiquitous organic phosphates (adenosine monophosphate, phosphatidylserine, methyl phosphonate) and thus provides a mechanism for phosphate recycling on the early Earth. We propose that this process promoted stable surface water productivity, bridging the two-billion-year gap between an anoxic and oxygenic phosphate cycle.
