Excerpt from Agricultural Science Review, Vol. 2: Winter 1964 Tribolium castaneum (a ﬂour beetle) and mice were the biological materials chosen. The beetles have a generation interval of approximately four weeks at optimum temperatures and are easy to culture in a dry medium. Dr. A. E. Bell of the Population Genetics Institute had shown their use fulness in population genetics research. His full cooperation has made possible a series of investiga tions with Tribolium. This rapidly reproducing organism is merely used as a tool for establishing the principles of directed evolution and for testing new concepts. In fact, for these purposes, labora tory animals are peerless. The Tribolium research has included the discovery of a trait (larval weight.)
