Gene flow between ancient human groups is difficult to detect. In a closed deme, variance in a morphological trait should decrease over short time periods due to genetic drift. Previous studies have thus regarded increases in within-site trait variance over time as a possible indicator for new genetic variation through flow or the physical movement of individuals. This interpretation depends on archaeological context, as diachronic changes in population variance may also arise from selection,...
