Analytical Techniques for Cartesian Coordinate Data with Reference to the Relationship Between Hylobates and Symphalangus (Hylobatidae; Hominoidea)

Abstract

Hylobatid cranial similarities are examined using Cartesian coordinates describing morphological landmarks. While Symphalangus appears distinct from analysis of raw coordinates, it is less so when analytical procedures are included for controlling the influence of general size. This weakens arguments for maintaining siamangs as a distinct genus from Hylobates.
