Technical Abstract: Because rRNA genes encode relatively complicated molecules which appear to evolve slowly and are not laterally transferred from one species to another, changes in rRNA are thought to provide a evolutionary clock that runs at a more or less constant speed. True phylogenists have been dismayed by the observation that many simple biochemical traits (e.g. antibiotic resistance) can be easily changes or transferred from one species to another, and microbial physiology has been treated as only the 'flesh' that adorns the true 'phylogenetic skeleton.' Given the observation that the FDP/phosphate regulatory web: 1) confers many metabolic advantages, 2) is a complicated scheme, and 3) only appears to be found in bacteria sharing a common 16S rRNA ancestry, it may be possible to relate these aspects of macrophysiology to the phylogeny of other low G+C gram-positive anaerobes.
