The specificity of biological objects. From physics to biology tier 2.

The coupling of generic objects, defined by their symmetries, on the one side, and the corresponding trajectories, on the other side, is at the core of the objectivation of phenomena understood in existing physical theories. As for proper biological phenomena, we hypothesize that they do not possess stable theoretical symmetries. Thus, biological objects are specific in the sense that they are the result of historical and contingent changes of symmetries. This provides a specific notion of randomness, proper to biological phenomena.
