Natural selection leads to evolution by giving the organism that is best suited for the area to thrive. Thus those who not suited for the area die off and evolution moves forward.

a species can gradually change into new species
Natural selection means that, over successive generations, lineages with traits that benefit their carriers in their given habitat are more likely to persist and thrive than lineages with traits that benefit their carriers to a lesser extent or not at all.
For instance, in arctic conditions, families of wolves with a thinner pelt might produce, on average, fewer offspring than families of wolves with a thicker pelt, and so the alleles that are associated with thinner rather than thicker pelts will, over successive generations, fade from the population.
Because there's always variation in all heritable traits, this means that the average phenotypical makeup of a population is always drifting, changing.
Summarizing: natural selection doesn't exactly 'lead to' evolution: natural selection is a part of evolution, a contributing factor. You might say it's the part of evolution that gives evolution direction.
Natural selection is, the nonrandom survival and reproductive success of randomly varying organisms.
Evolution is the change in allele frequency over time in a population of organisms.
So, as organisms become reproductively successful they leave more progeny with the alleles that made them more reproductively successful and then the alleles in the populations gene pool are changed in frequency, the representation of alleles changes, and evolution takes place

Small changes add up over time. :)
Small changes add up over time.
Many small changes can create a whole new species

Perhaps not, but evolution can exist without natural selection.
In evolution, natural selection is often called survival of the fittest.
his development in science is that he created the natural selection
Random processes are not part of the theory of evolution by natural selection.
Adaptions that lead to greater survivability and reproductive success in the immediate environment of the individual organisms under selection pressure.
Natural selection is one force that can lead to evolution.natural selection is one cause of evolution
Adaptive change and speciation.
No, natural selection is believed to result in evolution.
Mutation, Natural Selection, Migration, and Genetic Drift.
Natural selection leads to evolution by giving the organism that is best suited for the area to thrive. Thus those who not suited for the area die off and evolution moves forward.
Perhaps not, but evolution can exist without natural selection.
Natural selection is one of the 'guiding' principles of evolution.
influence either survival or reproduction.
I'm sorry, but I can't make heads or tails of this question.
Evolution by natural selection.
The only thing that causes evolution is Mutations due to forced natural selection of desired alleles.
Natural selection directs evolution; it cannot stop or prevent it.
