Paleolithic Period, also spelled Palaeolithic Period, also called Old Stone Age, ancient cultural stage, or level, of human development, characterized by the use of rudimentary chipped stone tools. The Mesolithic is the Old World archaeological period between the Upper Paleolithic and the Neolithic. The term Epipaleolithic is often used synonymously, especially for outside northern Europe, and for the corresponding period in the Levant and Caucasus. Neolithic, also called New Stone Age, final stage of cultural evolution or technological development among prehistoric humans. ... The Neolithic followed the Paleolithic Period, or age of chipped-stone tools, and preceded the Bronze Age, or early period of metal tools. Hominids are the group of primates that includes humans, gorillas, and chimpanzees, among others. The word hominid originally referred only to humans, and its Latin root reflects that: homo, or "man." Today scientists use it to talk about any of the great apes (including humans).
