Inferring clocks when lacking rocks: the variable rates of molecular evolution in bacteria

<p>Abstract</p> <p>Background</p> <p>Because bacteria do not have a robust fossil record, attempts to infer the timing of events in their evolutionary history requires comparisons of molecular sequences. This use of molecular clocks is based on the assumptions that subs...
