Strand Vidarsdóttir, U. and Cobb, S. (2004) 'Inter- and intra-specific variation in the ontogeny of the hominoid facial skeleton : testing assumptions on ontogenetic variability.', Annals of anatomy., 186 (5-6). pp. 423-428.
In this paper we use geometric morphometric techniques to test two assumptions that are commonly made about variations in facial ontogeny: closely related species, or members of the same species, will share a common early post-natal ontogeny; and closely related species, or members of the same species, will share a common ontogenetic scaling trajectory. To test these assumptions we use four species of hominines: Homo sapiens, Gorilla gorilla, Pan troglodytes and Pan paniscus. The first assumption is falsified, both inter- and intra-specifically, using discriminant analysis with crossvalidation of subadults prior to the onset of the eruption of the permanent dentition. The second assumption only holds true for inter-specific comparisons of ontogenetic scaling trajectories, while assumptions of variation in intra-specific scaling trajectories are falsified with these data.
