Life in ancient oceans enabled by erosion from land
Description: As scientists continue finding evidence for life in the ocean more than 3 billion years ago, those ancient fossils pose a paradox. Organisms, including the single-celled bacteria living in the ocean at that early date, need a steady supply of phosphorus, but it's very hard to account for this phosphorus unless it is eroding from the continents. So that makes it really hard to explain the fossils we see at this early era. Discoveries of fossil remains of bacteria from over 3 billion years ago have changed that picture.
