Natural selection says that the fittest genes will be passed on. If a slightly different color will give a survival advantage, this will be passed on. This example can be applied to any gene.
Evolution has also occurred in the field of computers, telephones, etc. What works best and gives an advantage will be used.
Evolution by natural selection.
Evolution by natural selection actually relies on variation within a population. Without variation, there would be no genetic differences for natural selection to act upon, leading to no evolution. Variation provides the raw material for natural selection to work with, allowing beneficial traits to be favored and passed on to future generations.
Short and memorably answer. Natural selection is the nonrandom survival and reproductive success of randomly varying organisms. Natural selection is the main driver of adaptive change leading to evolution.
Natural selection may ultimately be his downfall.
Yes, natural selection requires genetic variation to drive the process of evolution. Genetic variation provides the raw material for natural selection to act upon, leading to changes in the traits of a population over time.
The leading theory concerning the mechanism of evolution is natural selection.
Natural selection is the process by which certain traits that provide a reproductive advantage become more common in a population over time, leading to evolutionary change. Evolution is the overall change in a population's genetic makeup over successive generations, driven by mechanisms such as natural selection. In essence, natural selection is one of the primary mechanisms through which evolution occurs.
No, natural selection is believed to result in evolution.
That the theory of evolution by natural selection fits the facts of evolution. The theory of evolution by natural selection is based on myriad lives of converging evidence and is the best explanation we have for the adaptive changes leading to speciation in populations of organisms.
Perhaps not, but evolution can exist without natural selection.

False. Isolation promotes natural selection of the unique mutations and recombinations in an isolated population, thus leading to evolution.

Natural selection directs evolution; it cannot stop or prevent it.
Natural selection is one of the mechanisms that shapes adaptation and enables evolution.
