Modularity is a concept introduced by Mary Jane West-Eberhard[1]. She correctly sensed patterns in evolution. All her patterns however stick to the old concept of morphological presentations. This point is overcome by fauceir theory that admits functional patterns. In this sense her concept of modularity is superseded by fauceir theory now. The modularity of functional units remains, however. We will use the term modularity not as a concept of evolution, but to illustrate how the fauceir concept is arranged.
