Преодоление «языкового рубикона»: версии, ступени и эволюционные механизмы

Abstract

The most plausible hypotheses explaining the breakthrough of our distant ancestors to articulate speech and consciousness include: rituals of solidarity (singing, grooming, facial expressions, gestures), the role of "labor", teaching children, changes in gender relations, recruiting (mobilization for collective action), laryngeal transformation, brain growth, mirror neurons, neuronal overlap; dominance of coalitions over loners, self-domestication, the need to coordinate decisions; joint intentionality, development of normativity. The concretization of the principle of "cultural drive" leads to the following concept: new environmental, social and communicative challenges and concerns lead to multiple trials; successful behavior is consolidated in group practices, mental structures of participants, and hereditary inclinations with multilevel selection and change of many generations. Overcoming the "language Rubicon" took place in several steps, or stages, in which the structures that have developed to provide concerns lead to new concerns that require new structures. Such concerns as pacifying social order in the group, signaling general discontent, coordinating actions, etc., the following structures emerged: egalitarian coalitions with collective practices of intimidation, sound signals uttered in unison, training and self-training, self-domestication, shared intentionality, and normative rituals. The most plausible versions supplement this concept. Сhoral singing as a ritual of solidarity promoted the ability to imitate and articulate. Mirror neurons and neural overlaps have played the role of providing mechanisms for imitation and association processes. The connection between "labor" and speech was complex and interdependent, mediated by normativity. Recruiting as signals of mobilization for collective action also made its contribution but only under the already established normative order. Social learning is in fact a special ritual of constant trial and adjustment which has grown out of a normative ritual. The establishment of a new order of sexual relations also played a role: under the prohibition of violence and rape it was necessary to involve partners. Speech replaced grooming, and those who spoke clearly, convincingly and/or sang beautifully received benefits in sexual selection. The totality of all these processes reinforced the concerns of mutual understanding which were provided by the rituals of naming with the following multiplication of protowords and further growth of linguistic complexity.
