The Paleolithic or Palaeolithic (from Greek: παλαιός, "palaios", "old"; and λίθος, "lithos", "stone" lit. "old stone", coined by archaeologist John Lubbock and published in 1865) is the earliest division of the Stone Age. It covers the greatest portion of humanity's time (roughly 99% of "human technological history", where "human" and "humanity" are interpreted to mean the genus "Homo"), extending from 2.5 or 2.6 million years ago, with the first documented use of stone tools by hominans such as "Homo habilis", to the end of the Pleistocene around 10,000 BCE. The Paleolithic era ended with the Mesolithic, or in areas with an early neolithisation, the Epipaleolithic.
