Rock Bands Spin an Oxygen Record
The rise of oxygen on early Earth may have been caused by a microbial changing of the guard between methane-producers and oxygen-producers. This swap may have been initiated by a drop in the ocean’s nickel abundance. Continuing studies of the world’s largest iron ore deposits could cement the case.
