We are fortunate to have Dr. Bengston as the Illg Distinguished Lecturer in 2015. His main interests concern the origins and early evolution of multicellular organisms, including animals. One of the greatest innovations in the history of life has been multicellularity-the ability of cells to stick together to form larger and more complex organisms. Multicellularity distinguishes microbes from plants and animals, and most life forms visible to the naked eye are multicellular.
Multicellularity has arisen many times during evolution, through different mechanisms and in different lineages. Of those lineages that survived, only a few have gone on to form advanced mulitcellularity, where cells specialize for diverse functions. Continue Reading
