Prehistoric art developed over millions of years from the earliest humans to the Neolithic period. The Paleolithic period saw the first known artworks created with stone tools, including cave paintings between 30,000-13,000 BCE depicting animals and humans. The Mesolithic and Neolithic periods saw the development of agriculture and permanent settlements, with art becoming more representational of humans and used for ornamentation and architecture. Key characteristics of Neolithic art included figurines, pottery with designs, and megalithic constructions.
