Question

How has artificial selection by humans helped in the evolution of different vegetables? Explain in brief with example

Answer 1

Humans have developed different varieties of vegetables from a single wild cabbage by artificial selection some of these are as follows —
(i) Some farmers have wanted to select very short distances between the leaves and developed the present day cabbage.
(ii) Some farmers selected immature green flowers and developed the broccoli.
(iii)Some have selected the sterile flowers and developed the cauliflowers.
(iv) Some farmers selected the swollen part of the wild cabbage and developed the kohlrabi.
(v) Some of them have selected the larger leaves and developed Kale.

So, all these vegetables are descended from a common ancestor.
