We have seen that the history of the evolution of matter is, in both the inanimate and living worlds, the history of a series of symmetry breakings. The chiral molecules built into the fundamental cornerstones of the living organism set the path of further breakings of symmetry in the course of phylogenesis. The asymmetry of the right-twisting DNA molecule was the precursor of a number of molecular consequences, and other symmetry breakings affected living creatures either indirectly or as the result of a combination of external influences.
