This chapter discusses the dynamical hierarchies in biological systems and molecular systems as well as higher-order dynamical hierarchies. In biological systems, hierarchies with multiple functionalities at different scales can be found everywhere. On the molecular level, novel functionalities can arise in at least two ways: by assembly; and by evolution. The properties associated with each level are generated by the collective dynamics of the elements in these dynamical hierarchies; however, here arises the problem of creating a formal framework for consistently describing such hierarchical systems, with a procedure for moving between levels. It is probably necessary to embrace assembly and evolution as two complementary and equally important aspects of how to generate bio-complexity that can account for the generation and prevalence of dynamical hierarchies in living systems.

Keywords:   dynamical hierarchies, biological systems, molecular systems, hierarchical systems, assembly, evolution, bio-complexity, novel functionalities
