Instructions:
Explain how climatic changes and increase in population led to the growth of agriculture.
Explain how human beings started using agriculture to control animals.
Solution:
Hunter-gatherers used to obtain their food by hunting animals and collecting food items such as wild berries, fruits, edible roots, etc. from forest.
Due to some major changes in the climate, the surrounding of the earth became increasingly warmer.
Due to these sudden climatic changes large portions of forest were converted into grasslands.
Grasslands are vast areas covered with grass and grass-like plants.
These grasslands provided fodder for grazing animals and edible grains for human beings.
As a result, human beings came in close contact with these grazing animals and plants.
People likely started observing the places where edible plants grew and came to know how a plant grows from a seed.
They started protecting these plants from animals and gradually started farming.
As people started to practise agriculture more and more, it started attracting animals near their camp.
They started to feed these animals and started protecting them from wild animals.
This was done in order to get a continuous supply of dairy products and meat.
Thus hunter-gatherers started farming and herding.
