Extract

Almost at the end of his chapter on Mutation, G. G. Simpson in 1953 in The Major Features of Evolution noted that “There is also increasing evidence that mutation rate is itself, to some degree, a genetically controlled character.” If for mutation one uses the broad definition of the origin of new hereditary types, then the glimmerings to which Simpson referred now have become a documented fact at the molecular level.
