Macaque gene frequencies for seven polymorphic protein systems are employed to generate dendrograms via two algorithms. The frequency data employed are drawn from 14 populations of macaques representing nine species. The two algorithms are the unweighted pair group method and an iterative program based on the additive hypothesis. The topologies generated by the two approaches are quite similar. The one major difference, involving M. fuscata, is investigated in detail. As measured by our index of dissimilarity (ID) conspecific populations of M. nemestrina, M. mulatta and M. fascicularis are closely related. Often the ID values separating conspecific groups are in agreement with expectations based on geographic considerations. Interspecific comparisons involving M. mulatta and M. fascicularis also exhibit clinal variation. M. cyclopis and M. fuscata show a particularly strong relationship to M. mulatta. This cluster of three species is closely related to M. fascicularis. M. speciosa, on the other hand, appears to be the most divergent of the species analyzed. The results are considered in light of previous thoughts about macaque systematics based on morphological characteristics.
