Dynamic models of development and the mechanistic-organismic controversy

Starting with a prototypical model of Newtonian mechanics, a sequence of dynamic models with increasing structural complexity is presented. The implicated smooth variation along a dimension of structural complexity yields dynamic models which display organismic properties such as stagewise development and emergent self-organization. Consequently, it is concluded that dynamic models of development are inherently neutral with respect to the mechanism-organicism controversy. Accordingly, a unitary research program is proposed in which these dynamic models serve as building blocks for the construction of a coherent explanatory system of development.
