Evolution is the change in allele frequency over time in a population of organisms.
Natural selection is the nonrandom survival and reproductive success of randomly varying organisms.
So, if an organism is selected by having greater reproductive success than it's conspecifics this organism will leave descendents that have the traits for this success and if enough descendents start making up a greater bit of the population then genes( alleles ) will change in frequency and evolution will take place.
Natural selection is also the driver of adaptive change leading to speciation.

What is another word for Darwin's theory of natural selection?
Evolution by natural selection.
Why is genetic variation important for natural selection to drive evolution?
Genetic variation is important for natural selection to drive evolution because it provides the raw material for natural selection to act upon. Without genetic variation, there would be no diversity in traits for natural selection to favor or eliminate, and evolution would not be possible.
What scientist had ideas about evolution and adaptation that influenced Darwin?
Jean-Baptiste Lamarck, a French biologist, proposed the idea of inheritance of acquired characteristics and the concept of transformational evolution. These ideas influenced Darwin's thinking on evolution and adaptation. However, Darwin's theory of natural selection ultimately diverged from Lamarck's ideas.
Evolution by natural selection works best on populatin having no variation?
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.
Which scientist is known for the theory of evolution through natural selection?
Charles Darwin is known for the theory of evolution through natural selection. He proposed that all species of life have descended over time from common ancestors, and that the process of natural selection is the mechanism through which this evolution occurs.
Is natural selection a cause of evolution?
No, natural selection is believed to result in evolution.
Can natural selection exist with out evolution?
Perhaps not, but evolution can exist without natural selection.
What is another word for Darwin's theory of natural selection?
Evolution by natural selection.
Darwin's theory of evolution by natural?
Evolution by natural selection.
What is the application of natural selection theory to human society?
Sociobiology is the application of natural selection to human society Humans are the product of natural selection at the individual level and the product of evolution at the population level, so the human generated society is influenced by the natural selection of individual humans.
Which type of natural selection prevents evolution?
Natural selection directs evolution; it cannot stop or prevent it.
How are evolution and natural selection related?
Natural selection is one of the mechanisms that shapes adaptation and enables evolution.
Is evolution a natural selection?
Natural selection explains the process of evolution: evolution by natural selection. It basically means that species with the highest fitness (survival rate) will live, and be selected by nature for the characteristics they possess that make them more apt to survive. Because of natural selection, evolution occurs.
In evolution survival of the fittest refers to?
In evolution, natural selection is often called survival of the fittest.
What was Charles Darwin's contribution to science?
his development in science is that he created the natural selection
What principles is not part of Darwin's original theory of evolution by natural selection?
Random processes are not part of the theory of evolution by natural selection.
