Part 1 Periodic distribution of properties in chemical elements and minerals: periodicity in chemical elements; periodicity in minerals. Part 2 Periodic distributions of functions in living organisms: period flight; period vision; period placenta; period bioluminescence; period penis; period return to aquatic life; period placental-marsupial equivalence; period high mental ability. Part 3 How the order inherent in matter and energy paved the way to biological periodicity: the three evolutions that preceded the biological one. Part 4 The production of "carbon copies" at the different organization levels: atomic, molecular, and biological mimicry and its significances for periodicity; the collaboration between mineral and gene product; cellular processes inherited from the elementary particles and the chemical elements; the transfer of mineral order to the cell-cellular processes inherited from the minerals. Part 5 The contribution of differential reproduction and death to periodicity: chromosome behaviour is an internally regulated process; mutation is a directed process in bacteria and higher organisms. Part 6 The role of the development in the establishment of periodicity: development and evolution are two aspects of the same phenomenon; the onset of reproduction determines whether a development stage will be considered an evolutionary or an embryological event; the same larval type gives rise to different phyla; Larvae and adults of the same species are as different as animals belonging to distant groups; similarities between tunicae and vertebrate larvae; juvenile stages and the onset of reproduction in plants. Part 7 Relationship between the environment and periodicity: the ability of organisms to change with the environment is already present in minerals; genetic and the environment. Part 8 Structural periodicity - the ordered addition of components in atoms, molecules, and living organisms: ordered addition of components in atoms and molecules; ordered transformation in minerals; ordered transformation in plants; integration of components in invertebrates; addition of components in vertebrates. Part 9 Macromolecular and atomic mechanisms responsible for periodicity: the formation of new mosaic proteins and the sudden reappearance of old proteins; cascades of molecules and of gene activations are irrevocable events that produce integrated packages of structures and functions; the relationship between chemical and biological periodicity; a consequence of periodicity is the prediction of novel biological transformations.
