The hydrogen hypothesis for the first eukaryote

摘要: A new hypothesis for the origin of eukaryotic cells is proposed, based on comparative biochemistry energy metabolism. Eukaryotes are suggested to have arisen through symbiotic association an anaerobic, strictly hydrogen-dependent, autotrophic archaebacterium (the host) with a eubacterium symbiont) that was able respire, but generated molecular hydrogen as waste product anaerobic heterotrophic The host's dependence upon produced by symbiont put forward selective principle forged common ancestor cells.
