Simplistic View On Evolution

This is the environment.




These are the organisms.



This is the phenotype.




These are mutations. The phenotype does not much change.




Genotype explores the environment, learns about the limits suitable for living. If the environment (including diseases) does not change, the genotype stays in steady state.




The environment changes. Inbreeding occurs (sexual), mutations become obvious, phenotype swells.




Genes are in desperate search for new environment. New exists are found due to the memory obtained when the living conditions were good and stable.




Two incompatible genotypes are now created.
