  We studied a relations between the triplet frequency composition of
mitochondria genomes, and the phylogeny of their bearers. First, the clusters
in 63dimensional space were developed due to $K$-means. Second, the clade
composition of those clusters has been studied. It was found that genomes are
distributed among the clusters very regularly, with strong correlation to
taxonomy. Strong co-evolution manifests through this correlation: the proximity
in frequency space was determined over the mitochondrion genomes, while the
proximity in taxonomy was determined morphologically.
