Describe the main stages of the origin and development of selection.

The initial stage of selection was domestication (from lat. Domesticus – domestic) – the conversion of wild organisms into cultural ones. Grain cereals became one of the first cultivated plants.
The primitive selection, which was conducted by ancient farmers and pastoralists, consisted in a spontaneous (unconscious) selection for breeding the best individuals of plants and animals, more prolific and adapted to exist next to humans.
With the development of agriculture and success in studying the heredity and variability of organisms, primitive selection has been replaced by combination selection based on methodological (conscious) selection of individuals and their crosses to obtain the desired combination of characters in hybrids.

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
