Explanation:
The Mesolithic era is also known as the Middle Stone Age, it can be dated approximately between 10000 to 8000 BC. The cultures of this period developed varied local adaptations to special environments. Mesolithic populations were often forced to become migrating hunters and settle in rock shelters and the development of agriculture of this period of time helped the rise of enduring settlements. Some Mesolithic people sustained the hunting, while others trained the early stages of domestication as well. Mesolithic tools were usually compound devices manmade with small fragmented stone tools called microliths.
