Epigenetics is scientifically an occasion to rejuvenate completely interdisciplinary research. Epigenetics is necessarily a long argumentative chain. Arguments come from biotechnology as much as environmental science or social science. Specialists of these disciplines are building their definitions of epigenetics and are already working together to develop a common language. Epidapo will be the place where this common language will have the better chance to thrive consciously, thanks to a special dedication to science reflexivity.
