Ammonia-oxidizing archaea (AOA) are chemolithoautotrophs that dominate nitrification in today’s low ammonium ocean, playing critical roles in the global nitrogen cycle, alongside ammonia-oxidizing bacteria (AOB) that favor higher ammonium environments. Nitrification may have occurred soon after the origin of oxygenic photosynthesis and provided fundamental nutrients for the emergence of eukaryotic organisms in the Proterozoic; however, the timing of biological evidence remains unclear. Here we show using phylogenetic models that AOA occurred ~1,165 (1,928-880) Mya in...
