Prokaryotes arose during the Precambrian Period 3.5 to 3.8 billion years ago. Prokaryotic organisms can live in every type of environment on Earth, from very hot, to very cold, to super haline, to very acidic. The domains Bacteria and Archaea are the ones containing prokaryotic organisms. read more

Prokaryotes live in nearly all environments on Earth. Some archaea and bacteria are extremophiles, thriving in harsh conditions, such as high temperatures (thermophiles) or high salinity . Many archaea grow as plankton in the oceans. read more
