Dated gene duplications elucidate the evolutionary assembly of eukaryotes - Nature
Analysis of eukaryotic gene sequences using a relaxed molecular clock methodology indicate that eukaryotes emerged 3.0–2.25 billion years ago as a result of mitochondrial endosymbiosis with complex archaea that already possessed an elaborated cytoskeleton, membrane trafficking, endomembrane, phagocytotic machinery and a nucleus.
