how is the method of artificial selection by human helped in the evolution of different vegetables
Answers
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 or Brassica 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.
We can observe a great variation in plants. By the help of knowledge humans and by the passage of time, humans created totally different species.
For example, variants in wild cabbage are as follows.
(I) Short distances between leaves, led to the formation of green leaf buds, which is a common cabbage.
(II) Bred broccoli
(III) The variant with sterile flowers has made the cauliflower.
(IV) Kholrabi
(V) Kale
