The Mesolithic age or otherwise called the Middle Stone Age was a period in the development of human technology between the Palaeolithic and Neolithic periods of the Stone Age. The Mesolithic period began the end of the Pleistocene Epoch at some around 20,000 years before the present and ended with the introduction of agriculture of around 12,200 years ago. Mesolithic age was short and poorly defined. By about 18,000 years ago, humans crossed into the North America from Asia through via Beringia, at present, a submerged land bridge that existed when the sea levels were lowered during the Ice Age. Around 15,000 - 12,000 years ago, they rapidly spread across North and South America. After the climate became warmer and the ice sheets retreated. As the last Ice age ended, the regions that experienced greater environmental effects have a much more evident Mesolithic Era lasting a millennia.
Societies were able to live well on rich food supplies from the marshlands fostered by the warmer climate. As moving on through a favorable climatic conditions, the humans began to adopt the ideas of the agricultural techniques and consequently, in forested area, the first signs of deforestation have been found in order to create space for the agricultural purpose. The Mesolithic period was characterized by small composite flint tools like microliths and microburin; and also by introduction fishing tackle, stone adzes and wooden objects like canoes and bows.
