Notes. 1. K1, number of substitutions per site that lineage 1 accumulated starting from the split with lineage 2; dK, the difference between K1 and K2 numbers of substitutions; sd_dK, standard deviation for dK; P, significance value for differences in substitution rates between lineage 1 and lineage 2; Ratio, the ratios of the branch length leading to the lineage 1 to that leading to the lineage 2 since the divergence of the two lineages.

2. HOM = hominoids, OWM = Old World monkey, NWM = New World monkey.

3. *significant at 0.05 level; **significant at 0.01 level; ***significant at 0.001 level.
