title: Towards a theory of meaning in biology: a proposal for an operative definition.
abstract: Information is a concept developed inside the context of computational and computer sciences. Entropy is a concept developed inside physics context. The best concept in biology is that of "meaning" which is quite impossible to be measured as stated by some examples which are reported. A suggestion to develop a discussion in order to obtain an integration of these concepts inside the general problems of evolutionary biology is here reported to the attention of researchers.
