The document summarizes the key differences between the Paleolithic and Neolithic Ages in 3 main areas: food, shelter, and tools. In the Paleolithic Age, people hunted and gathered food without farming, lived in temporary shelters as they followed food sources, and used simple stone tools. In contrast, the Neolithic Age was characterized by farming, domestication of animals, permanent homes made of timber or bricks, and more advanced tools such as bows, arrows, and spear tips.
