There is evidence for alteration of bacterial genomes through evolutionary times and some of the pressures and molecular mechanisms underlying these changes have been investigated. Models such as the Barlow-and-Hall system are proving very useful in understanding evolution and predicting change in natural populations of bacteria. Use of genomics, study of the fossil record, identification of environmental stresses, past, present, and future, and modeling are all important to increasing our knowledge and understanding of the mechanisms and consequences of bacterial genome diversification. Using the most modern molecular techniques to define bacteria taxa, the eubacteria are divided into 23 phyla. For the past 50 years nomenclature of bacteria has been in constant flux as new species and genera are added or removed for the standard systematics. These changes reflect the latest fashions in classification and the application of new molecular and physiological methods for characterizing bacteria. Insight into the richness of genetic potential in the world around us is essential if we are to protect our natural environmental heritage and leave to our posterity a world that is vital and healthy.
