The Paleolithic era, also known as the Stone Age, is a prehistoric period of human history that lasted roughly 3 million years until the development of agriculture around 10,000 BCE. It is characterized by the use of stone tools and the hunting and gathering lifestyle of early human societies. Researchers in the field of Paleolithic archaeology study the material culture, art, social organization, diet, and technological advancements of ancient human populations during this time period. They also investigate the cognitive and behavioral evolution of early humans, as well as their interactions with the environment and other species. This research area provides valuable insights into the origins and development of human societies and their adaptation to different environments.
