Explanation:
Artificial selection helps to produce organisms with desired trait or combination of traits.This method also explains us that different looking structures can evolve from the same origin. For example, different vegetables are evolved from wild cabbage. Some farmers wanted to select for very short distances between leaves, and have bred the cabbage we eat. Some wanted to select for arrested flower development, and have bred broccoli, or for sterile flowers, and have made the cauliflower. Some have selected for swollen parts, and come up with kohlrabi. Some have simply looked for slightly larger leaves and come up with a leafy vegetable called kale. So, cabbage, cauliflower, broccoli, kohlrabi and kale are descended from the same ancestor, wild cabbage by artificial selection.
