Resumen

RESUMEN La epigenética, concepción frecuentemente atribuida a Corad Waddington (1905-1975), ha estado estrechamente relacionada a una lucha en el campo intelectual por más de dos mil años. Postulada por Aristóteles bajo la denominación de epigénesis, en oposición a la concepción biológica preformacionista de Demócrito, ha ido variando en sus contenidos y alcances en consonancia con el desarrollo del conocimiento científico. En la actualidad la epigenética se presenta en la literatura científica como un concepto con rasgos polisémicos y escasa integración conceptual. Sin embargo, la gran amplitud de fenómenos biológicos que abarca y la magnitud de la producción científica involucrada hacen necesario un nuevo acercamiento que integre ecología, evolución y desarrollo (eco-evo-devo). Se propone en este sentido conceptualizar la epigenética desde una perspectiva adaptativa, que implica la inclusión de mecanismos epigenéticos transgeneracionales o darwinianos, dependiendo del nivel de integración que se analice. Esto permitiría integrar conceptos y resolver contradicciones en áreas de la biología funcional y evolutiva

ABSTRACT The epigenetic concept, frequently attributed to Corad Waddington (1905-1975), has been closely related to a fight in the intellectual field for more than two thousand years. Postulated by Aristotle under the name of epigenesis, as opposed to the biological preformationists conception of Democritus, it has varied in content and scope in accordance with the development of scientific knowledge. Today, epigenetics is presented in the literature as a polisemic concept with low conceptual integration. However, the wide range of biological phenomena covered and the extent of scientific production involved demand a new integrated approach to ecology, evolution and development (eco-evo-devo). In this sense, it is proposed to conceptualize epigenetics from an adaptive epigenetic perspective, which involves the inclusion of transgenerational epigenetic or Darwinian mechanisms, depending on the level of integration to be analyzed. This would allow to integrate concepts and solve contradictions in areas of functional and evolutionary biology.
