Question

Explain the effects of changing environment around 12,000 years ago.

Answer 1

• Around 12,000 years ago, there was a change in the climate of the world. There was an increase in the temperature of their environment.
• It resulted into the development of grasslands in many regions which in turn led to an increase in the number of animals that ate grass like deer, antelope, goat, sheep, cattle, etc. This encouraged people to herd and rear these animals. They also engaged themselves in fishing.
• Several grain bearing grasses such as wheat, barley and rice also grew around this time in different parts of the sub-continent. Men, women and children began to collect these grains to use them as their food. Eventually, they learnt the art of growing these grains and harvesting them.
• As agriculture progressed, these grasslands attracted more and more animals towards it, who wandered around the human settlements. This encouraged people to herd and rear these animals. By then they had also learnt how to fish.
• Humans also learned that by looking after the animals, they could have easy access to all the sources of animal products like meat, milk and milk products, skin, bones and teeth.
