Randomness.
The common factor in the three types are that dominant traits are preferred.
Because natural selection only preserves incremental beneficial traits to the organism and many different areas of the organism are undergoing mutation and natural selection at the same time against the backdrop of the immediate environment. If a population of organisms, subject to allele change due to natural selection, is not in a changing environment, or split in a allopatric event, then adaptive change will be very slow, or will not happen at all and selection will winnow those variants and stabilizing selection is taking place. Regression to the mean of phenotype.
Adaptation does not allow for natural selection: natural selection causes adaptation.
Genetic variation in itself does not 'support' natural selection: it is what natural selection acts upon.
Randomness.
Overproduction
Variations within a population
Variation in the organisms under selection. In both artificial selection and natural selection there must be heritable variations that have the possibility of being in the case of artificial selection what the selector wants in the organism and in thje case of natural selection survivability and reproductive advantages.

natural selection
One factor that affects survival and natural selection is genetic variation. Genetic variation within a population allows for individuals with traits that better suit their environment to survive and reproduce, leading to the passing on of advantageous traits to future generations through natural selection.

Mutation is the important " starter " of the adaptive change engendered by natural selection. Variation is key to selection and without variation in organisms there would be nothing to select from for the survival and reproductive success of the organism against the immediate environment.
