Onto-phylogeny
Evolution of Species and Development of the Individual

Biology recognises two entities where the existence seems to be an immediate given of perception and not a theoretical elaboration or the result of an experimental approach. These first entities are the species and the individual, and biology seeks to explain their genesis and their operation. Firstly, the theory of natural selection explains the evolution of species (phylogeny) and secondly, the theory of genetic programming explains the development of individual organisms (ontogeny). The author believes that this way of dividing biology no longer holds true given the experimental data acquired recently. He is suggesting a new theory called onto-phylogeny which, on the contrary, unifies biology. In this context, the evolution of species and embyronic development result from a single, extended natural selection process.
