Teleología Naturalizada: Los conceptos de función, aptitud y adaptación en la Teoría de la Selección Natural (Naturalized Teleology: The concepts of function, fitness and adaptation in Natural Selection Theory) [PDF]

open access: yes, 2013
En la Teoría de la Selección Natural, el concepto de función biológica debe suponerse para delimitar el concepto de aptitud; y éste debe suponerse para delimitar el concepto de adaptación y también para explicar el fenómeno al que este último alude ...
