Scaling analysis is in some ways a better method for comparing molecular distance matrices than cluster analysis. Principal coordinates analysis of sequencing and immunological data for anthropoid primates reveals consistent similarities and few differences between different macromolecular systems. Considerable congruence is also demonstrated between the biochemical distances and a morphological system. Different molecules show significantly non-linear covariation, possibly relating to differential rates of molecular evolution within the primates.
