A wild variety of a plant may show different variations. Humans have selected some such variants and grown them for generations and during the course of time, they have become totally different species. For example, variants in wild cabbage were selected on the basis of certain features to generate different vegetables. (i) Short distances between leaves, led to formation of green leaf buds-the common cabbage. (ii) Arrested flower development has bred broccoli. (iii) The variant with sterile flowers has made the cauliflower. (iv) Variant with swollen leaf parts-kohlrabi. (v) Variant with larger leaves-kale.

Artificial selection is a process in which man selects a particular desired traits for breeding, in order to generate new plants/ animals with improved characters. For e.g. Early farmers cultivated wild cabbage orBrassica oleracea. This wild cabbage developed into many varieties such as cabbage, broccoli, kohlrabi, cauliflower, kale, and brussels. These varieties were artificially selected because of their characteristic traits.
