This is a picture of broccoli. Broccoli has been cultivated from wild mustard through artificial selection. Artificial selection is a selection process in which evolution can occur. Humans have modified species, since before Darwin and Wallace, over many generations by selecting and breeding individuals that possess desired traits. An example is with how farmers and breeders have caused evolution in farm stock by only allowing plants and animals with desirable characteristics to reproduce. This process is called artificial selection because people, instead of nature, select which organisms are "better suited" to survive and reproduce.
