This study documents odontometric variation in four populations of related genetic background. It is found that the transplanted populations of Cuanalan and Saltillo have undergone significant microdifferentiation in tooth size relative to the two home valley populations. The extent and direction of this microdifferentiation is seen as reflecting differential amounts of admixture from African and European sources in demographic subunits of the two transplanted populations. The dental variables found to discriminate significantly between populations are the same variables predicted to be evolutionarily labile by Butler's Field Theory. Principal component analysis confirms the presence of morphological fields in these data and supports the position that each class has a stable tooth, with stability decreasing with increasing distance from the key tooth. The importance of hybridization in determining which variables significantly discriminate between populations is confounded by the effects of development of the dentition in morphogenetic fields. These data suggest the odontometric data provide an adequate, if somewhat conservative, base from which to evaluate microdifferentiation of human populations
