Long Answer Type Question:

What was the impact of the change in the environment around 12,000 years ago?

Answer 1

Major changes in the climate of the world with a shift to relatively warm conditions were noticed around 12,000 years ago. As a result, grasslands developed in many regions. This resulted in an increase in herbivorous animals like deer, antelope, goat, sheep, and cattle. This encouraged people to herd and rear these animals. They also engaged themselves in fishing.
Several grain bearing kinds of grass 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. By the time, they also learned where these grains grew and when they ripened.
