When a mutation occurs in the replication process, it changes certain features, like maybe better eyesight, and maybe bigger eyes, or bigger claws, and the meaning of evolution is when something changes into a better form.
Natural Selection
Natural selection explains adaptive change in the immediate environment.
Natural selection is the most powerful driver of evolution and it is the only mechanism of evolution ( genetic drift and gene flow are two other mechanisms ) that leads to adaptive change. Natural selection is the nonrandom survival and reproductive success of of randomly varying organisms. Evolution is the change in allele frequency over time in a population of organisms.
The book, On The Origin Of Species, " suggested " that organisms evolve through the process of natural selection. The nonrandom survival and reproductive success of randomly varying organisms
These three ideas seem to run together, so it's important that you are able to distinguish among them. The theory that organisms change over time is evolution. The mechanism by which organisms evolve is natural selection. Survival of the fittest explains how natural selection works.Answer = Natural SelectionThe process of natural selection, of course.
Evolution is the change in allele frequency over time in a population of organisms. Change over time and a fact. Natural selection is the nonrandom survival and reproductive success of randomly varying organisms and explains much about the fact of evolution.
Natural selection is the changing of organisms gradually over time. Natural selection and evolution are parts of environmental science due to them being the studies of organisms.

A simplified explanation. Natural selection is the nonrandom survival and reproductive success of randomly varying organisms who by this reproductive success change the allele frequency over time in populations of organisms, which is evolution.
Without beneficial mutations leading to beneficial variation there would be no natural selection on the individual organism, outside of sexual recombination, which would mean no change in allele frequency over time leading to no evolution. Fortunately, that is never the case in nature and mutations lead to variation and adaptive change in the organisms under selection pressure.
False. Organisms change over time due to evolution, which is driven by natural selection (survival of the fittest) and artificial selection (human intervention). This process leads to the adaptation and diversification of species.
That organisms vary, by sexual recombination or mutation. That some organisms will be better at survival and reproduction so that their alleles are passed on to progeny and these causes a change in frequency of these alleles over time which is the definition of evolution.
Natural Selection
The theory of evolution by natural selection. It explains evolution; the change in allele frequency over time in a population of organisms. Why organisms change over time in differing environments.
No. Evolution is the change in allele frequency over time in a population of organisms. This may be the result of stabilizing selection, but is still evolution.
