The evolution in coding DNA sequences brings new flexibility and freedom to the codon words, even as the underlying nucleotides get significantly ordered. These curious contra-rules of gene organisation are observed from the distribution of words and the second moments of the nucleotide letters. We apply these statistical data to determine the relative positions of a few bacterial groups as per their divergence in the geological timescale.
