This paper posits that the gene-centered viewpoint of the organism (gene-centrism) is not enough to explain biological complexity. Organisms are not completely determined by their genomes; rather, living beings can be seen as interpreters or intentional systems. Epigenetics is the framework that allows the avoidance of gene-centrism and permits the emergence of a more holistic standpoint where determination and novelty can coexist, as shown with examples taken from developmental biology and macromolecules folding. In summary, as P. Medawar and J. Medawar wrote: "Genetics proposes; epigenetics disposes."
epigenetics; genetic determinism; gene-centrism
