The theory of societies, like
modern general systems theory, pictures a world
made up of societies within societies (systems within systems) That is, societies do not just line up side by side like mosaics — they form «nested hierarchies» that go from subatomic particles through
cells to animal bodies, or through stars to galaxies.
Modern psychosomatic medicine has
made some progress in analyzing along these lines; for example, it seems quite possible that the emotional tone of my soul may directly alter the patterns of physical feeling in my stomach.4 Still, we should not suppose too quickly that the aims of a human personality have any very effective direct influence on the molecules of body
cells, other than those in the brain.

modern cells, proteins are used to
make the components of the code.
Modern cells use RNA to
make proteins, the workhorses of cellular function, but RNA likely preceded both proteins and DNA.

modern molecular, microscopy, and
cell biology techniques in a handful of spiralian model systems have
made that possible.
These less acknowledged mechanisms of interaction and molecular control might have
made the initial pathways to prebiotic systems evolution more intricate, but were surely essential for sustaining far - from - equilibrium chemical dynamics, given their functional relevance in all
modern cells.
