ABSTRACT
The Semantic theory of evolution depends upon the Ribotype theory of the cell because it needs the description of the cell as a trinity of fundamental categories. It also depends upon the Ribotype theory of the origins, because the idea of adaptation to natural cycles requires a consistent reconstruction of the cycle which first came into existence and which is the basis of all other cycles of life: the cell cycle. The concept of adaptation to natural cycles may look like an abstraction, but it also looks like the essence of evolution. The experiments in population genetics which study the mechanism of evolution are set up a priori as experiments of adaptations of organisms to niches, and in this way they are bound to be tests for natural selection only. The Darwinian idea that organisms keep tracking the environment in a never-ending chase accounts for gradual transformations.
