During the Paleolithic Age, people hunted and gathered food, lived nomadically without permanent homes made of materials like mammoth bones and fur, and wore clothing made of fur and animal skins. They used basic tools like sharpened sticks and stones. In contrast, during the Neolithic Age people farmed and herded animals, lived in permanent timber and mud brick homes, wore wool from domesticated sheep, and used more advanced tools such as harpoons and bows and arrows.
