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.

Which is more likely to be true natural selection or evolution?

Evolution, of course. Evolution can happen without natural selection in some cases; drift, flow. Generally though, natural selection causes evolution and then, by definition, would come first.
