One of the exciting changes in bacterial genetics that has occurred in the past decade is the development of methods and information permitting the study of real evolutionary genetics with respect to bacteria and their genomes. Sufficient data are available to permit researchers to address problems similar to those that for many years have held the interest of geneticists studying eukaryotic organisms. Although the bacterial evolutionary situation is not totally understood, our present comprehension has shed new light on classic problems in genetics and offers the promise of even more interesting results in the years to come.
