Abstract

The aim of the present communication is to contribute to the discussion about the existence of laws in biology. In order of it the argumentation of J.J.C. Smart against their existence and the discussion of it made by M. Ruse and R. Munson are first reconstructed. The examination of this controversy shows that, despite of the differences between the first of the authors mentioned and the other two in relation to the problem of laws in biology, the three share the assumption according to which in the case that there are laws (in strict sense or fundamental) in genetics, they must be some of the so-called “Mendel’s laws”. In the present communication, and from a revision of the metascientific concept of fundamental law, the above assumption is questioned, proposing an alternative analysis, based on a structuralist reconstruction of genetics.
