This research began as a collaboration between Don Melnick, a population geneticist who has worked extensively with mitochondrial DNA variation in macaques, and Wolfgang Dittus, who has been studying the behavioural ecology and population biology of the toque macaque in Sri Lanka for over two decades. Guy Hoelzer and Mary Ashley each conducted postdoctoral research in Melnick's lab and have since established their own research laboratories.

Surveys of mitochondrial DNA (mtDNA) variation in macaque monkeys have revealed extremely high levels of intraspecific divergence among haplotypes. One consistent pattern that has emerged from these studies is that divergent haplotypes are geographically segregated so that sampling a few matrilines from a given region shows them to be identical, or a closely related subset of haplotypes. Geographically structured mtDNA variation has also been commonly observed in other taxa. In this study, haplotype variation and distribution are studied in detail within a local population of toque macaques. The results show that highly divergent haplotypes, differing by 3.1% in their nucleotide sequences, coexist in this population and that they may be spatially segregated even on this micro-geographic scale. Furthermore, these differences are maintained between social groups that exchange male migrants, and thus nuclear genes, frequently.
