Explanation:
- The world's climate underwent significant shifts around 12,000 years ago, moving from relatively cold conditions to rather warm ones.
- This resulted in the creation of grasslands in numerous locations.
- As a result, there were more deer, antelope, goats, sheep, and cattle—animals that depended on grass—to thrive.
- A recent study revealed that the extinction of numerous megafauna species in the southern region of what is now South America occurred around 12,000 years ago as a result of the introduction of people in Patagonia and a changing environment.
- Because of farming, people could stop travelling in search of food.
- Instead, they started settling down and cultivating crops or raising livestock on surrounding property.
- To defend themselves, they erected stronger, longer-lasting dwellings and walled up their towns.
