Postulates of Micromolecular Evolution

  • Otto Richard Gottlieb


Is it biosynthetic diversification or is it biosynthetic simplification of chemical structure which runs parallel with evolution? The answer to this old problem of micromolecular systematics is: it is both. The difference is one of hierarchy. Evolution on a higher systematic level is accompanied by contraction of reaction steps and oxidations and on a lower level by expansion of reaction steps and deoxygenations. These postulates are embodied in two principles of micromolecular systematics which, together with two additional principles, are derived from the interpretation of a broad data base (Chaps. 4–14) for different biogenetic groups diversified in the major plant taxa.
