Morphometric differences and distances are theoretically equivalent whether based on Cartesian coordinate locations of landmarks, or on the linear measurements between those same landmarks. In two examples: (a) two‐dimensional primate odontometrics and (b) three‐ dimensional hominoid pelvic osteometrics, much similarity is found between analyses using input data in the form of chords and coordinates. The subtle differences attain statistical significance, however, with the greater interspecific separation and delineation of trends consistently favouring chords in one example and coordinates in the other.
