Paleolithic period

(pā'lēəlĭth`ĭk, –lēō–, păl'–) or

Old Stone Age,

the earliest period of human development and the longest phase of mankind's history. It is approximately coextensive with the Pleistocene geologic epoch, beginning about 2 million years ago and ending in various places between 40,000 and 10,000 years ago, when it was succeeded by the Mesolithic periodMesolithic period
or Middle Stone Age,
period in human development between the end of the Paleolithic period and the beginning of the Neolithic period. It began with the end of the last glacial period over 10,000 years ago and evolved into the Neolithic period; this

. By far the most outstanding feature of the Paleolithic period was the evolution of the human species from an apelike creature, or near human, to true Homo sapiens (see human evolutionhuman evolution,
theory of the origins of the human species, Homo sapiens. Modern understanding of human origins is derived largely from the findings of paleontology, anthropology, and genetics, and involves the process of natural selection (see Darwinism).

). This development was exceedingly slow and continued through the three successive divisions of the period, the Lower, Middle, and Upper Paleolithic. The most abundant remains of Paleolithic cultures are a variety of stone tools whose distinct characteristics provide the basis for a system of classification containing several toolmaking traditions or industries.

The Lower Paleolithic Period

The oldest recognizable tools made by members of the family of man are simple stone choppers, such as those discovered at Olduvai Gorge in Tanzania. These tools may have been made over 1 million years ago by AustralopithecusAustralopithecus
, an extinct hominin genus found in Africa between about 4 and 1 million years ago. At least seven species of australopithecines are now generally recognized, including Australopithecus afarensis, A. africanus, A. bahrelghazali, A.

, ancestor of modern humans. Fractured stones called eoliths have been considered the earliest tools, but it is impossible to distinguish man-made from naturally produced modifications in such stones. Lower Paleolithic stone industries of the early species of humans called Homo erectusHomo erectus

 include the Choukoutienian of China and the Clactonian, Chellean-Abbevillian, Acheulian and Levalloisian represented at various sites in Europe, Africa, and Asia, from 100,000 to 500,000 years ago. Stone tools of this period are of the core type, made by chipping the stone to form a cutting edge, or of the flake type, fashioned from fragments struck off a stone. Hand axes were the typical tool of these early hunters and food-gatherers.

The Middle Paleolithic Period

The Middle Paleolithic period includes the Mousterian culture, often associated with Neanderthal manNeanderthal man
or Neandertal man
, a species of Homo, the genus to which contemporary humans belong, known as H. neandertalensis after Neanderthal (now Neandertal), Germany, the valley where the first specimen to be identified was found.

, an early form of humans, living between 100,000 and 40,000 years ago. Neanderthal remains are often found in caves with evidence of the use of fire. Neanderthals were hunters of prehistoric mammals, and their cultural remains, though unearthed chiefly in Europe, have been found also in N Africa, Palestine, and Siberia. Stone tools of this period are of the flake tradition, and bone implements, such as needles, indicate that crudely sewn furs and skins were used as body coverings. Since the dead were painted before burial, a kind of primitive religion may have been practiced.

The Upper Paleolithic Period

In the Upper Paleolithic period Neanderthal man disappears and is replaced by a variety of Homo sapiens such as Cro-Magnon manCro-Magnon man
, an early Homo sapiens (the species to which modern humans belong) that lived about 40,000 years ago. Skeletal remains and associated artifacts of the of the Aurignacian culture were first found in 1868 in Les Eyzies, Dordogne, France.

 and Grimaldi man. This, the flowering of the Paleolithic period, saw an astonishing number of human cultures, such as the Aurignacian, Gravettian, Perigordian, Solutrean, and Magdalenian, rise and develop in the Old World. The beginnings of communal hunting and extensive fishing are found here, as is the first conclusive evidence of belief systems centering on magic and the supernatural. Pit houses, the first human-made shelters, were built, sewn clothing was worn, and sculpture and painting originated. Tools were of great variety, including flint and obsidian blades and projectile points. It is probable that the people of the Aurignacian culture migrated to Europe after developing their distinctive culture elsewhere, perhaps in Asia. Their stone tools are finely worked, and they made a typical figure eight–shaped blade. They also used bone, horn, and ivory and made necklaces and other personal ornaments. They carved the so-called Venus figures, ritual statuettes of bone, and made outline drawings on cave walls.

The hunters of the Solutrean phase of the Upper Paleolithic entered Europe from the east and ousted many of their Aurignacian predecessors. The Solutrean wrought extremely fine spearheads, shaped like a laurel leaf. The wild horse was their chief quarry. The Solutrean as well as remnants of the Aurignacian were replaced by the Magdalenian, the final, and perhaps most impressive, phase of the Paleolithic period. Here artifacts reflect a society made up of communities of fishermen and reindeer hunters. Surviving Magdalenian tools, which range from tiny microliths to implements of great length and fineness, indicate an advanced technique. Weapons were highly refined and varied, the atlatlatlatl
[Nahuatl], device used to throw a spear with greater propulsion. Atlatls began to be used in the Americas in the post-Pleistocene period and were eventually replaced by the bow and arrow.
