How are heredity, variability, and reproduction related to life on Earth?

Reproduction or reproduction is the ability of organisms to reproduce their own kind. Reproduction is based on matrix synthesis reactions, i.e., the formation of new molecules and structures based on information embedded in the DNA nucleotide sequence. This property ensures the continuity of life and the continuity of generations. Heredity – the ability of organisms to transmit their signs, properties and developmental features from generation to generation. The basis of heredity is the relative constancy of the structure of DNA molecules. Variability is the opposite of heredity; the ability of living organisms to acquire new traits that are different from the qualities of other individuals of the same or different species. Variability due to changes in hereditary inclinations – genes, creates a variety of material for natural selection, i.e., the selection of individuals most adapted to the specific conditions of existence in nature. This leads to the emergence of new life forms, new species of organisms.
