Answer:
Between the Paleolithic and the Neolithic eras, there was a transitional period known as the Mesolithic Age. It possesses traits from both the Paleolithic and Neolithic eras. In addition to hunting, fishing, and gathering food, inhabitants of this era later domesticated animals to supplement their diets. Mesolithic Irish people were hunters and gatherers. The family groups would have resided in homes made of animal skins laid over a bowl-shaped timber structure near rivers and lakes. Smaller chipped stone tools replaced larger chipped stone stools as the preferred seating option (microliths). Hunting big herds of animals in packs gave way to a more hunter-gatherer way of life. At the conclusion of the Mesolithic Age, mankind started cultivating crops and raising animals under controlled conditions. The advent of agriculture, which dramatically altered human lifestyles, coincided with the Mesolithic age. Most significantly, the development of agriculture encouraged people to settle down permanently because they were no longer forced to hunt for food. However, many people continued to hunt actively throughout the Mesolithic Age, therefore hunting did not completely disappear at this time. In the Mesolithic Age, permanent communities ranged from hut-built cities to hut-based villages.
