This process is thought to have started in bacteria, which used their metabolic products, such as hydrogen sulfide and methane, as an energy source for growth and reproduction. The term "leptogenesis" also refers to a group of organisms that are capable of producing organic compounds through this process. These organisms include the archaea, which have been observed using
