when humans breed an animal for a certain trait.
NO. Both artificial and natural selection are forms of Evolution in general. Both cause variation by selection within a particular population. The only difference is who is doing the selection, humans or nature.
Maybe u should actually answer because i'm to tupid to know the answer/ The artificial selection although controlled by the choices of humans created novelty in the races. During natural selection the environment is responsible for selecting the best types. Darwin's ideas of natural selection were based on the fact of struggle for existence and survival of the fittest. Thus by artificial selection some of the races have been developed which can sustain the present environmental conditions. this has contributed to his ideas.
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.
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.

Some theorems on artificial selection was created in 1934.
Nature plays no direct role in artificial selection. That is the difference between artificial selection and natural selection. Nature does play some indirect roles in artificial selection. One indirect role is in providing the organisms with which one beings the artificial selection. Another is in influencing the choices of the organism performing the artificial selection.
Variation in the organisms under selection. In both artificial selection and natural selection there must be heritable variations that have the possibility of being in the case of artificial selection what the selector wants in the organism and in thje case of natural selection survivability and reproductive advantages.
Artificial selection.
This type of selection is called artificial selection.

In artificial selection, nature provides the variations, and humans select those they find useful.
The process by which humans breed organisms to obtain certain traits is known as artificial selection.
