The relationships between a range of modern human samples are assessed from cladistic analyses of the published population frequencies of tooth crown characters, using new data on the Krapina Neanderthal sample as an outgroup. All of the most parsimonious trees show an early divergence of African and Australasian groups. This result is compared with an alternative dendrogram proposed by Turner (1992). Reconstruction of a hypothetical dental ancestor suggests that the similarities between the African and Australasian groups result from the retention of symplesiomorphous dental traits. Additionally, despite expectations from multiregional evolution, recent Europeans are dentally less like the Krapina Neanderthals than are Africans and Australians.
