Buena parte de la elegancia del concepto de selección natural reside en una falsa aparienciade sencillez, y a menudo se expresa metafóricamente. En este artículo reviso diferentesmetáforas de la selección natural con el fin de revelar algunas complejidades ocultas. Enrealidad, el concepto de selección natural es un concepto difícil estrechamente relacionadocon otros conceptos complejos, tales como el concepto de eficacia biológica y de adaptación.Una discusión sobre las metáforas de la selección natural es pertinente porque la imagenque ellas evocan puede obstaculizar (...) la investigación del proceso natural al cual se refieren.

The argument from design and Aquinas’ fifth way: In scientific literature it is common to make equivalence between the so-called argument from design and the fifth way of Thomas Aquinas. It is commonly assumed that both demonstrations for the existence of God are based on the concept of finality to proof the need for an intelligent being capable of causing order in nature. However, we think that the differences between the two arguments have great significance: each of them have as (...) starting point a different type of order, are based on a different kind of finality, and the way in which they use the principle of causality is also different. We believe that such differences permit us to say that the two arguments are not at all comparable and may even be seen as opposite arguments. (shrink)
