Morphometric studies in the taxonomy of the orang-utan (Pongo pygmaeus. L. 1760.
The purpose of this study is to verify the subspecific level of the two recent refugial groups of Orang-utan on Borneo and Sumatra. A total of 47 skulls from both regions were studied by means of 32 craniometric characters. Univariate analysis showed highly significant differences only in males, whereas multivariate statistical analysis led to complete discrimination in both sexes. These results support the assumption that the geographically isolated Orang groups are subspecies.
