Evolution of the gibbon subgenera inferred from cytochrome b DNA sequence data

Abstract

DNA sequences for the mitochondrial cytochrome b gene from the four extant gibbon subgenera are described. The data confirm that the gibbon subgenera evolved from a common hylobatid ancestor and suggest that they diverged from each other after the divergence of the extant African great ape species. The cytochrome b gene does not resolve the evolutionary relationships between the gibbon subgenera themselves.
