Natural variation in artificial selection is used because humans choose from among the naturally occurring variation s in species. Natural selection is related to species fitness because Darwin called natural selection survival of the fittest because those that could survive would carry their species on there for being the naturally selected.
In artificial selection, nature provides the variations, and humans select those they find useful.

Charles Darwin used data on artificial selection the least to support his theory of natural selection. While artificial selection played a role in shaping his understanding of how traits can change over generations, he focused primarily on observations of variation in nature and the role of competition and adaptation in driving the process of natural selection.
I don't think there's a certain type as such. Selection and Elimination can be structured or random. Random is self-explanatory, structured, is based on the individual/the criterion, i.e. I will pick all the green and red Easter eggs out of a packet, etc.
Artificial selection
One long argument with supporting evidence for the theory of evolution by natural selection. Starting with artificial selection, used as an analogue for natural selection, and ending with the distribution of animals, biogeography, Darwin showed the species arose through natural process over long lengths of time.
Artificial selection.Artificial selection is the selection, by humans, of which individual plants or animals to breed from. In this way desirable characteristics, such as increased yield or disease resistance, can be preserved or improved.Charles Darwin used artificial seletion as a model for how evolution could take place in nature, where competiton between individuals replaced the selective action of humans. He called the natural process 'natural selection'.See http://evolution.berkeley.edu/evosite/evo101/IIIE4Evochange.shtmlfor an excellent account.
Artificial Selection , as the breeding is carried out artificially by humans .
Its because of artificial selection.
Humans affect artificial selection by selectively breeding organisms with desirable traits, leading to changes in their genetic makeup over generations. By controlling the mating of organisms, humans can accelerate the process of evolution to develop specific characteristics in plants, animals, and other organisms. This process has been used in agriculture, animal husbandry, and even in pets to produce desired traits.
The term that is often incorrectly used to describe evolution by natural selection is "survival of the fittest."
If RNA is used as a genetic molecule, passing traits from parent to offspring, then it is subject to natural selection. This only happens in a number of viruses and very few bacteria, though: most organisms use DNA as their genetic molecule.
