Evolution

We know from biology that evolution is a process of selection, like natural or sexual selection, by which living organisms tend to improve their capacity to survive and/or reproduce. We also know from biology that this process is a consequence of the successful transmission of genes. Evolution is not about the survival of the individual, but the survival of genes. And the genes that survive are the ones who carry the information that allows them to successfully transmit themselves.

Evolution and complexity

We know evolution mainly from biology, but evolution is in the end a physical process. And like all physical process, it is related with the stability of systems. In the case of evolution, it is related with the stability of genes. Evolution happens because it increases the continuance of genes. And a change that increases the continuance of genes is a change that takes genes into states of higher stability.

Genes are self-duplicating complex systems that increases their stability as a consequence of an evolutionary process.

Complexity is the reason for which evolution is possible. Particles, atoms and minerals don’t evolve because they are simple systems, therefore they have more rigid dynamics (see Complexity). It is only complex systems, like living organisms, that have a flexible dynamics that allows evolution to happen.

Unlike development, evolution might or might not be related with an increase in complexity. For example, species might evolve into different breeds, varieties or types with no increase in complexity.

And just like development, evolution is not an inevitable process. Things don’t tend to evolve ‘naturally’. Things, by nature, tend to remain in the most stable states. Things only evolve when changes in the system increases its stability. That is, when changes in the organism improves the continuance of genes.
