Dynamical Patterning Modules
Dynamical Patterning Modules
This chapter discusses the developmental-genetic mobilization of physical forces in the origin of animal body plans and presents a plausible basis for the emergence of key mechanisms of developmental pattern formation from ingredients that existed in the unicellular world. It shows that the dynamical patterning modules (DPMs) transformed simple, spherical, topologically solid cell clusters into hollow, multilayered, elongated, segmented, folded, and appendage-bearing structures. The chapter concentrates on the properties of the major DPMs, and also offers an integrated account of macro- and microevolutionary change for the early phases of multicellular life.
Keywords: physical forces, dynamical patterning modules, multicellular life, developmental pattern, animal body
