A semimechanistic model has recently been proposed to explain observed correlations between the H and O isotopic composition of hair from modern residents of the USA and the isotopic composition of drinking water, but the applicability of this model to hair from non-USA and preglobalization populations is unknown. Here we test the model against data from hair samples collected during the 1930s-1950s from popula- tions of five continents. Although C and N isotopes con- firm that the samples represent a much larger range of dietary ''space'' than the modern USA residents, the model is able to reproduce the observed d 2 H and d 18 O values given reasonable adjustme...
