Is it the right ansatz?

This article is a response to Rasmussen et al[Artificial Life, 7, 329-350], in which the authors suggest that, within a particular simulation ''framework'', there is a tight correspondence between the complexity of the primitive objects and the emergence of dynamical hierarchies. As an example they report a two-dimensional artificial chemistry that supports the spontaneous emergence of micellar structures, which they classify as third-order structures. We report in this article that essentially comparable phenomena can be produced with relatively simpler primitive objects. We also question the order classification of the micellar structures.
