There was an idea first proposed in 1916 — that plants with rapid reproductive cycles evolve faster - and a team of Yale scientists writing in Science say they have confirmed it using 2008 computing power.
Long involved with the Tree of Life Web Project, which is attempting to reconstruct the “tree” representing the genealogical relationships of all species on Earth, Michael Donoghue, the G. Evelyn Hutchinson Professor of Ecology & Evolutionary Biology and Curator of Botany at Yale’s Peabody Museum of Natural History, has spearheaded the study of flowering plant evolution. In animals, the variation in rate of molecular evolution has been ascribed to differences in generation time, metabolic rate, DNA repair, and body size; in plants, the differences have been more difficult to determine.
