How has the method of artificial selection by humans helped in the evolution of different vegetables ? explain in brief with examples.
Answers
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.
Short distances between leaves, led to formation of green leaf buds—the common cabbage.
Arrested flower development has bred broccoli.
The variant with sterile flowers has made the cauliflower.
Variant with swollen leaf parts kohlrabi.
Variant with larger leaves kale.
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
