title: [Gestural forms of communication in primates. II. The relation of gestures to acoustic signals and tool activities in primate phylogeny].
abstract: The connection between the frequency of acoustic signals application, contact and gestural communication and the manipulation activity of Cercopithecidea and Anthropoidea have been examined. A scheme reflecting the changes of correlational behavioural systems at different periods of primate phylogenesis is proposed. The behavioural changes in the connections of gestures, vocalisation and manipulation activity during the process of their transition into the language and labour on the way to hominization are shown. On the basis of the exact data a possible role of gestural an acoustic signals in the origin of language is given.
