Abstract
In opposition to the etiological conception of biological functions, this paper attempts to show that explanations by natural selection, far from justifying functional attributions, presuppose them, and that these attributions may be understood by appealing to a particular specification of the systemic conception of function, that is, the biological conception of function. The paper argues that the etiological conception of biological function is based on two fundamental errors: confusing the concept of function with the concept of adaptation, and confusing selectional explanations with functional analyses. This explains the inappropriate demand that those analyses include an etiological explanatory aspect and make possible the distinction between adaptations and exaptations.
Contrariando la concepción etiológica de las funciones biológicas, se pretende mostrar que las explicaciones por selección natural, lejos de justificar atribuciones funcionales, las presuponen; y que estas atribuciones pueden ser entendidas apelando a una especificación particular de la concepción sistémica de función que llamaré concepción biológica de función. Se argumenta que la concepción etiológica de función se basa en dos errores fundamentales: confundir el concepto de función con el concepto de adaptación; y confundir las explicaciones seleccionales con análisis funcionales. Por eso la exigencia improcedente de que dichos análisis entrañen un contenido explicativo etiológico y posibiliten la distinción entre adaptaciones y exaptaciones.
