Refers to the earliest part of the Paleolithic Period, including most of the Pleistocene Epoch, from about 2,000,000 to about 250,000 Before Present. The earliest phase of the Lower Paleolithic period is characterized by the production of simple pebble tools by early hominids. Later Lower Paleolithic tradition includes the "Chopper chopping-tool industry," which is named for surviving stone tools, and which is widely distributed in the Eastern Hemisphere and is believed to have been the work of Homo erectus, who also probably made wood and bone tools.
