En los últimos años se han logrado grandes avances en el área de secuenciación y análisis de genomas completos que han aportado elementos para debatir varios de los postulados darwinistas de la evolución. La demostración de procesos de duplicación de genes y de genomas completos, la transferencia horizontal de genes y la teoría endosimbiótica cuestionan la idea de cambio evolutivo como un proceso de acumulación de pequeños cambios a través del tiempo geológico. La evidencia de la selección neutral en el contexto genómico pone de manifiesto otros mecanismos de evolución, que no necesariamente van acompañados de un programa adaptacionista ni con la idea de progreso. En este artículo se presentan estos y otros conceptos adicionales tales como la regulación génica y los mecanismos moleculares del desarrollo y del ambiente como puntos de partida para el planteamiento de una teoría evolutiva incluyente y acorde a los conocimientos actuales."]]]],["element",{"elementId":"38"},["name","Coverage"],["description","The spatial or temporal topic of the resource, the spatial applicability of the resource, or the jurisdiction under which the resource is relevant"],["elementTextContainer",["elementText",{"elementTextId":"10674"},["text","2011-07-01"]]]],["element",{"elementId":"45"},["name","Publisher"],["description","An entity responsible for making the resource available"],["elementTextContainer",["elementText",{"elementTextId":"10675"},["text","Universidad Nacional de Colombia"]]]]]]],["tagContainer",["tag",{"tagId":"3916"},["name","Adaptacionismo"]],["tag",{"tagId":"231"},["name","evolución"]],["tag",{"tagId":"3917"},["name","genómica"]],["tag",{"tagId":"3918"},["name","neutralismo"]],["tag",{"tagId":"3893"},["name","Selección natural"]]]],["item",{"itemId":"2133","public":"1","featured":"1"},["fileContainer",["file",{"fileId":"2055"},["src","https://bvhumanidades.usac.edu.gt/files/original/187e8213f7c6bfc05fe4c9d7c0689af2.pdf"],["authentication","5c79cf851ee60c9e4c0e17e8d4edeed2"]]],["collection",{"collectionId":"5"},["elementSetContainer",["elementSet",{"elementSetId":"1"},["name","Dublin Core"],["description","The Dublin Core metadata element set is common to all Omeka records, including items, files, and collections.
