Paleolithic Europe, or Old Stone Age Europe, encompasses the Paleolithic or Old Stone Age in Europe from the arrival of the first archaic humans, about 1.4 million years ago until the beginning of the Mesolithic (also Epipaleolithic) around 10,000 years ago. This period thus covers over 99% of the total human presence on the European continent.[1] The early arrival and disappearance of Homo erectus and Homo heidelbergensis, the appearance, complete evolution and eventual demise of Homo neanderthalensis and the immigration and successful settlement of Homo sapiens all have taken place during the European Paleolithic.[2][3]
