Community selection number 2

However, over time, the chemical reserves of evolution turned out to be practically exhausted: all the acceptable chemical elements, as well as their sets, were mastered. Now there remained mainly the way of testing various combinations of the same atoms and blocks that make up the "molecules of life".

It was not chemical indicators that came to the fore, but structural ones, not chemical “perfection”, but structural ones. A very important step was the fragmentation of the protein shell into parts with different functions. There was a division of labor inside the cell (chloroplasts assimilate solar energy, and mitochondria - chemical; the membrane protects from harmful influences from the outside and facilitates the extraction of food from the external environment; the lysosome performs functions resembling food digestion, etc.). At the stage of chemical evolution, the prebiosphere penetrated to the molecular level. Complicated molecules as if absorbed energy and information from the environment. They turned into a kind of tiny storerooms, full of wealth. They began to not only absorb, but also radiate energy and information, creating special conditions around themselves. This changed the environment, helping to maintain the achieved level of complex complication, the cause of nomogenesis at this stage. What caused the creative activity in the selection? What directed him to create cells with the most complex and organized structure? It is possible that the solution is connected with the transition to multicellularity that began in those ancient times.

Suppose the first colonies crystallized, like minerals, from similar and fairly primitive cells. Began the process of selecting colonies. Is it possible, to some extent obeyed the laws of growth and competition of ordinary crystals. In the colonies, different cells, depending on their location (on the external border, inside, and in contact with a solid surface) were subjected to various external influences and therefore varied unevenly.

Even the mutations for them had to be different: the chemicals causing certain mutations were differently concentrated outside and inside the colonies. As a result, cells of the same type had to change differently, in different directions, depending on the place occupied in the colony. “External experiments” on creating the best screens were carried out intensively on the outer cells, and the most advanced assimilation apparatus of nutrients, reproduction, control, etc. on the inner cells. Cells with extraordinary, hypertrophied nuclei, membranes, and mitochondria appeared. Grew cell specialization.

Some became universal. True, all this is nothing more than a hypothesis. Complication of the cell structure could occur from within, with random mutations that made (blindly) corrections to the genetic information stored mainly in deoxyribonucleic acid molecules. Reproduction went quickly, there was enough time for experiments (about a billion years). It is usually considered that a cell, an organism is something secondary, as if an application to a genetic set, a means for its preservation and reproduction. Perhaps it is.
