Spontaneous and Induced Mutation

Abstract

IN his book "Bacterial Physiology" (New York, 1951), Dr. J. Lederberg writes, on page 94: "Not all workers have accepted the duality of adaptation mechanisms. Hinshelwood (1946), for example, has disregarded the selection of spontaneous mutants as an element of bacterial adaptations, apparently in order to bolster the applicability of his system of chemical kinetics to problems of bacterial growth". © 1953 Nature Publishing Group.
