Cranial metric and discrete trait variation and biological differentiation in the terminal Late Archaic of Ohio: the Duff site cemetery.
Cranial metric and discrete traits were collected from adult individuals of the terminal Late Archaic Duff site cemetery (33 LO 111). Comparisons of cranial metric traits among eight terminal Late Archaic samples including the Duff site sample showed that all samples shared the same generalized variance and by inference the same pattern of shape variation. Some significant size differences were found but these were interpreted as reflecting only minor differences in the underlying polygenic system or differences in environmental interactions. The overall similarity in cranial metrics among the terminal Late Archaic samples strongly suggests that they represent populations that, at least, shared a recent common ancestor. Analysis of discrete trait variation in all the terminal Late Archaic samples showed that the biological distances between samples are associated significantly with the between-sample geographical distances. This association accounts for approximately 25% of the variation in discrete trait frequencies. These results along with the results of the analysis of cranial metrics indicate that all of the terminal Late Archaic samples considered here are related, but geographically nearer samples are more closely related than distant ones.
