Phylogenetic analysis confirmed that two genes required for acetoclastic methanogenesis, ackA and pta, were horizontally transferred to the ancestor of Methanosarcina from a derived cellulolytic organism in the class Clostridia. This event likely occurred within the last 475 million years, causing profound changes in planetary methane biogeochemistry.
