The Principles of Life
The questions of what life is and how it first started have for a long-time daunted science. Our rather small understanding of what living systems are is demonstrated by the inexistence of a widely accepted chemical definition of them. This work intends to solve this long-lasting problem by laying such a definition as well as the principles that have governed living systems since their inception up to their extant forms. Here I show that living entities are productive chemical systems that bias their own formation. It will be shown that these two aspects inevitably lead to a selection by the highest replicative metabolic flux, explaining all the characteristics of extant living systems, where the strength of the biasing effect can be considered the main difference between life now, and at its origin. By building a narrative on how such a journey may have taken place, this work intends to provide the theoretical framework and experimental inspiration for a complete understanding of evolution, simultaneously creating new avenues to the search for extra-terrestrial life forms and opening the doors to the development of living technologies.
