Webb1 dec. 2014 · Endosymbiotic theory posits that plastids and mitochondria were once free-living prokaryotes and became organelles of eukaryotic cells. The theory started with plastids [1] and was further developed for mitochondria [ 2 ]. It was rejected by cell biologists in the 1920s and revived in the 1960s [ 3]. http://www.fossilmuseum.net/Evolution/Endosymbiosis.htm
