Paleolithic sites are archaeological locations where evidence of human activity from the Paleolithic era, also known as the Old Stone Age, has been discovered. This period, which lasted from about 2.6 million years ago to around 10,000 BCE, is characterized by the use of stone tools and the development of early human cultures. Notable examples of these sites include Lascaux, famous for its prehistoric cave paintings, and Olduvai Gorge, known for its significant fossil finds. These sites provide valuable insights into the lives of early humans, including their hunting practices, social structures, and artistic expressions. Artifacts such as tools, bones, and cave paintings help researchers understand the evolution of human behavior and the environment during the Paleolithic period. Preservation of these sites is crucial for ongoing studies in archaeology and anthropology.
