[Evolutional aspects of changes in the configuration of the foot]

At late stages of anthropogenesis a high positive "hand--foot" structural correlation was disturbed. In paleoanthropuses from the Sxul group and in the fossil man from Sungiry, an excessive development of the fibular components of the foot ("lateralization") was revealed. Certain evolutional and morphological causes contributing to the appearance of this rare variant are considered. A conclusion is made that development of lateralization in the foot can support the hypothesis on transition towards a leading role of the hand at the natural selection of the "hand--foot" system only at the latest stages of anthropogenesis.
