WitrynaHere we examine the origin and diversification of the eukaryotes in the Proterozoic Eon as viewed through fossils, organic biomarkers, molecular clocks, phylogenies, and redox proxies. Our interpretation of the integration of these data suggest that eukaryotes were likely aerobic and established in Proterozoic ecosystems. WitrynaThe Origin and Diversification of Eukaryotes. Key Concepts: 25 Eukaryotes arose by endosymbiosis more than 1 billion years ago 25 Multicellularity has originated several times in eukaryotes 25 Four "supergroups" of eukaryotes have been proposed based on morphological and molecular data 25 Single-celled eukaryotes play key roles in …

WitrynaThe origin of eukaryotes involved endosymbiotic assimilation of the bacterial ancestors of the mitochondrion and, in photosynthesizing lineages, the plastid ( 31, 32).
