Transitions Studies in Flowering Plants

by Rolf Baumberger

In fact, it appears that particularly exposed flowering plant populations can undergo morpho-genetic transformation in a very short time under environmental pressure. This can currently be observed in Diplacus. The Southern Californian yellow flowering plant Diplacus australis actively transforms under gradually changing environmental conditions (climate, pollinators) into the red-flowering form Diplacus puniceus. This process is sustainable and hereditary. It shakes up our understanding of the evolution of flowering plants. This phenomenon can also be observed in other flowering plants. We must even ask ourselves whether selection theory can play a significant role in this change. Or whether a more physical explanation could be applied here.

Transition in Diplacus


Challenge for a living being (DRAFT)

The real challenge for any living system is the fact that it is not stable over time; it is continuously disintegrating. Furthermore, the more complex its structure is, the faster it decays. It has a kind of half-life. A sophisticated living being is therefore forced to rebuild itself periodically from a much more stable cell stage. There must be degradable energy and metabolism. Information (DNA, RNA, and proteins) is also needed. Once rebuilt, this system is almost optimally configured. A nested, highly ordered structure achieves relatively high stability. That allows the system to release additional energy and thus becomes more stable. It is mainly located on a so-called attractor point. A short time later, it is already no longer ideal. Repair mechanisms prevent more significant damage before the cycle starts again. It is a truly Sisyphean task.


Evolutionary algorithm (DRAFT)

So if an attractor is no longer able to maintain the theoretical possibility for a living being in the optimal state, the living system decays, or an evolutionary algorithm comes into effect. A resulting force drives the system to a new stable point by an energy-consuming process. The transition takes place predominantly in the somatic cell structure. The search possibilities are limited, and there is a constant back and forth from the old to the new structure until the new structure is realized. If the new point is close, the new well-formed structure and small variation in the parameters involved make this immediately apparent (punctuated dynamic equilibrium). 


Important to know:
Living systems are well-ordered. Only by this circumstance, the existing structure is stable and is negentropic concerning the environment. It requires a constant flow of energy and information (metabolism). 
Since every living system is thought of being self-organizing, the evolution of these systems also must have self-organizing properties.
