Question

for how many years did the mesolithic age last​

Answer 1

Because the Mesolithic Period is characterized by a suite of material culture, its timing varies depending upon location. In northwestern Europe, for instance, the Mesolithic began about 8000 bce, after the end of the Pleistocene Epoch (i.e., about 2,600,000 to 11,700 years ago), and lasted until about 2700 bce.
