What is the difference between domestication and natural selection?

By definition, natural selection is the survival of the fittest.

Explanation:

Natural selection, in itself, is not a generator or creator of evolutionary novelties, but it only exposes certain variants.

Variants do not arise under the induction of the environment, but randomly, by chance, by a combination of genetic material, something that already exists in the genetic fund of a species.

Domestication is a term used for the process by which various biological organisms adapt to survive in society or through the work of human beings.

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.
