Humans are the only cause of artificial selection. Humans take organisms that they think are useful, or may become useful and they breed them true for traits they want in the organism and they cull the organisms that do not possess traits that humans find useful. not all animals can be artificially selected though.
They can do it by selecting traits in a species and breeding more with the same traits. These are often called GMOs. These GMOs have been around for a very long time. Look at all the breeds of dogs. The corn that we eat doesn't look like the original corn at all. GMOs are often given a bad name by the Organic Farming lobby.

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.
Adaptation does not allow for natural selection: natural selection causes adaptation.
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.
Humans have countered natural selection through hybrid breeding. Even crossing a male donkey with a female horse produces a mule. Crossing certain corn strains with other corn strains to produce more grain per ear.
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.
Humans
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.

Yes, it happens, but what is your question?
Yes, of course it does.
It's the other way around: natural selection is the natural process that causes the frequencies of occurence of alleles in the population gene pool to shift.
Humans directly affect artificial selection. They do this by selecting the specific traits that they prefer which they cannot don in a natural selection.
Natural selection is the process of selection imposed by pressures from the environment. It has no conscious guidance or purpose, but simply selects for a population best suited to survive in the current environment.Artificial selection is the process of selection consciously imposed by humans selecting which individuals breed. This can be considered a subset of natural selection, if one considers humans as just another part of the environment other creatures must live in.
They evolved by a process of natural selection.

These plants and animals were subjected to artificial selection so that the traits humans wanted in the organisms were selected for and the organisms not having these traits were culled. This, with some modification, is a good analogue for natural selection and artificial selection shows how organisms can be shaped over time with the proper selective pressures. The selective pressure of humans in artificial selection and the selective pressure of the environment in natural selection.
