Evolution in molecular structure and adaptive variance in metabolism.
1. A hypothesis is advanced to the effect that all metabolites, even minor ones, are expressed as a result of stimuli and are directed against or support actions on receptor systems. 2. In particular the hypothesis emphasizes the dynamic character of the secondary metabolite pattern as a function of physiological or environmental conditions and that the variations observed reflect the evolution of receptors. 3. Predictions based on this principle are experimentally verifiable. 4. The hypothesis has major implications in the entire area of life sciences.
