Abstract A rapid method, using 12 restriction enzymes, was employed to analyze variations in ribosomal DNA (rDNA) spacers in a study of phylogenetic relationships betweenHomo sapiens and related species. We mapped restriction sites in “the external and internal spacer regions and compared the arrangements of sites. The estimated sequence divergence betweenHomo sapiens andPan troglodytes, Pan paniscus, Gorilla gorilla, Pongo pygmaeus, Hylobates lar, H. agilis, andMacaca fuscata was 2.7, 2.3, 3.8, 7.3, 6.8, 7.8, and 14.1%, respectively. The genetic relationships inferred from these distances generally correspond to those inferred from analyses of other molecular markers in the literature. The divergence betweenH. lar andH. agilis and betweenH. lar andH. syndactylus was 0.34 and 2.4%, respectively.
