Explanation:
The Mesolithic era refers to the middle stage of the stone age i.e. between the Paleolithic and Neolithic. The Paleolithic refers to the old stone age and the Neolithic refers to the new stone age. During this time, the microlithic tools and other attacking weapons were made by the early humans, and also there occurred changes in their way of settlement as the climate and geography changed significantly.
