Joint EESS/GES Winter Seminar Series, Carl Simpson, Smithsonian Institution, National Museum of Natural History, "The major transitions link paleobiology and geobiology", Abstract: The major transitions are the evolutionary gain of a new level of hierarchical organization. During these transitions groups of bacterial cells evolve into eukaryotic cells, groups of eukaryotic cells evolve into multicellular organisms, and groups of multicellular organisms evolve coloniality. Each transition has lead to the restructuring of evolutionary and ecological process of geobiological consequence such as the origin of bioturbation and reefs. I will discuss my future work on the evolutionary basis of major transitions, their ecological and developmental consequences, and how major transitions link  paleobiology and geobiology through the partitioning of the limited energy available to life at multiple timescales.
