Explanation:
The transition from the Paleolithic to the Neolithic can be characterized as a huge progress in humankind's development. The man of the Old Stone Age (Paleolithic) led a nomadic lifestyle, continuously changing his place of residence. The primary reason for this is the search for food or hunting. It was a very uncertain process for Paleolithic man, and people then lived in small social communities. Such a lifestyle intensely called into question the survival of the community. The paleolithic man used the rough-hewn stone as a tool and weapon.
In the Neolithic, man organizes an evening of social communities. In these communities, a certain type of social organization has had a positive impact on life. These permanent dwellings made by man were called pile dwelling and dugouts. Man thus no longer had to lead a nomadic lifestyle. His daily life was also facilitated because he grew food, certain domesticated plants, and animal species, so he did not have to look for food. In the Neolithic, he used finely worked stone, which was also an improvement in the quality of tools and weapons.
