humans decide which It is important to note that natural selection is not the only way that species evolve. Artificial selection is an evolutionary process in which humans consciously select for or against particular features in organisms - for example, by choosing which individuals to save seeds from or breed from one generation to the next. If all 3 conditions are met Natural selection is a slow process that completes after many generations. Artificial selection and domestication is where humans take matters into their own hands. For example, in some grains, an increase in seed size may have resulted from certain ploughing practices rather than from the intentional selection of larger seeds. Organisms with the desired traits, such as size or taste, are artificially mated or cross-pollinated with organisms with similar desired traits. For thousands of years, humans have been influencing evolution, through changes we have caused in the environment and through artificial selection in the domestication of plants and animals. Artificial selection differs from natural selection, which is the process that results in the survival and reproductive success of individuals or groups best suited to their environment without human intervention. Apart from agricultural applications, one of the most common reasons for selective plant breeding is to produce esthetic adaptations. There can be unanticipated consequences of encouraging a specific trait.
