El estancamiento de la controversia sobre el seleccionismo génico

We address the scientific controversy about the plausibility of gene selection theory. First, we show that this controversy seems to be at a standstill as a whole and in particular regarding the central issue: whether genes are the unit of natural selection. Secondly, we claim that the standstill regarding this issue can be explained largely because the contending parties conceive genetics in different ways. Finally, we argue that the controversy could move forward if the highly problematic question of how to define “gene”, that has been neglected despite its relevance.
