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.

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.
No, natural selection is believed to result in evolution.
Perhaps not, but evolution can exist without natural selection.
Evolution by natural selection.
The process of natural selection and evolution can vary in terms of the time it takes, ranging from hundreds to millions of years depending on the species and environmental factors. Evolution is a gradual process that occurs over generations as populations adapt to their changing surroundings through natural selection.
No, there is genetic drift and gene flow between populations to consider.
Evolution by natural selection.
Natural selection directs evolution; it cannot stop or prevent it.
Natural selection is one of the mechanisms that shapes adaptation and enables evolution.
