    A major innovation in living organisms came about through the cooperation of two early simple cells, working together for their common benefit. Endosymbiosis is a variety of mutual symbiosis in which one organism lives inside another. This process represents a merger of branches of the “tree of life,” and is thus a form of horizontal gene transfer. The evolution of organelles (small, functional units within cells) resulting from endosymbiosis have led to major revolutions in the history of life, including the first protists and the eventual development of multicellular organisms such as plants, fungi, and animals.
