Artificial Selection
Artificial selection refers to the process of intentionally breeding desirable traits in either plants or animals. It is also known as selective breeding.
Natural variation, natural selection, artificial selection, genetic engineering, etc.
Selective breeding, which is a form of artificial selection.
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.
Humans directly affect artificial selection. They do this by selecting the specific traits that they prefer which they cannot don in a natural selection.
Artificial selection.
Natural selection seems to be the only selection that can drive speciation with powerful adaptive change. Sexual selection seems to stay within the species and both gene flow and genetic drift do not seem to drive speciation very well.
This type of selection is called artificial selection.
It is possible to have artificial selection in nature because of naturally occurring changes in the environment. These changes can greatly modify the organisms in question.
artificial selection
In artificial selection, nature provides the variations, and humans select those they find useful.
