Fisher?s fundamental theorem of natural selection formulated in 1930 predicts that life history traits (LHT), closely related with fitness, show lower heritability because they are slightly influenced by strong naturalselection and present lower additive genetic variance (1). By contrast, morphological traits (MT) are less related with fitness and they are expected to show higher heritabilities.In humans, although some studies have examined the heritability of LHT (2-8) and MT (9), none of them has analyzed the same sample for comparative purposes.In this study we assess and compare, for first time, the heritability of different of LHT and MT traits in a unique sample of crania and demographic records from Hallstatt (Austria).
