Influence of elementary evolution factors to gene pool of population.

Evolution follows the path of divergence.

The main moving force of evolution is natural selection.

The least unit of evolution is population.

5. Evolution is gradual and prolonged process, but unexpected overpatching may take place.

6. A species is complete self-contained system. Flow of genes is possible within a biological species.

7. Evolution practically stop outside of species, i.e. macroevolution there is because of microevolution only.

8. Genotypic variability is supplier of material for natural selection. Genotypic variability is randomicity.

9. Evolution is no predictable. It hasn't an ultimate aim.

Species (biological species) is totality of individuals that have similar morphological, physiological, biochemical, ecological, ecological, and genetic traits, living on fixed natural habitat, freely crossing each other, and giving fertile descendants.

Microevolution is totality of evolutionary processes taking place within population, and as a result of these processes a new species forms.

Macroevolution is an evolutionary process taking place on an above species level, and as a result of these process taxons bigger than species form (like genus, family etceteras).

Natural selection, mutations, migration, isolations, population waves, and genetic drift areelementary evolution factors.
