Piaget and the theories of organic evolution/Piaget e as teorias da evolucao organica

Theories of organic evolution, mainly those proposed by Darwin, have strongly influenced human sciences in general, and psychology in particular. Piaget has brought from biology several theoretical proposals which gave support to his formulations concerning human ontogenetic development. The theoretical link between biological and psychological formulations was based on the proposition of correspondences and partial isomorphism between evolutionary biology and cognitive development. However, Piaget's ideas about phylogenetic evolution of live organisms have had little influence over current biology. Nevertheless, epigenetic contemporary theories of biological evolution make use of Piaget's propositions, in theoretical opposition to the neo-Darwinist views. Because of that, it is proposed in this paper the crucial contribution of Piaget in terms of the proposition of a common theoretical ground for psychogenesis and organic evolution. Keywords: Development and evolution; epigenesis; psychogenesis; theories of organic evolution. As teorias da evolucao organica, principalmente a de Darwin, tiveram enorme impacto nas ciencias humanas, notadamente na psicologia. Piaget importou da biologia diversas formulacoes teoricas que fundamentaram as suas teorias sobre o desenvolvimento ontogenetico humano. A sua tese central estabelece a existencia de uma correspondencia de funcoes e isomorfismos parciais de estruturas entre a biologia evolutiva e as funcoes cognitivas dos sujeitos. Entretanto, suas ideias sobre a evolucao dos seres vivos, com enfase no papel do comportamento na evolucao, pouca influencia tiveram na biologia dominante de sua epoca. Nao obstante, as teorias epigeneticas contemporaneas da evolucao, em confronto teorico com o paradigma neodarwinista, reproduzem e atualizam as ideias piagetianas sobre a evolucao e desenvolvimento dos seres vivos. Nesse sentido, defende-se aqui a ideia segundo a qual Piaget formula plataforma teorica que estabelece bases comuns para a psicogenese e a evolucao organica. Palavras-chave: Desenvolvimento e evolucao; epigenese; psicogenese; teorias da evolucao organica.
