Paleobiogeographical considerations suggest the rate of evolution of the mitochondrial 12S rRNA gene is 1.0-1.6% per million years for the last dozen million years or so in the present genus [4] and ntDNA evolution rate has been shown to vary strongly even between different population of T. hermanni; [5] this restricts sequence choice for ...
