The Paleolithic era, also known as the Old Stone Age, is the earliest phase of human history, spanning from approximately 2.5 million years ago to around 10,000 BCE. This period is characterized by the development of early stone tools and a nomadic lifestyle based on hunting and gathering. The technological advancements during the Paleolithic, such as the creation of hand axes and spearheads, laid the foundation for later cultures and societal structures.
