The Pleistocene • There were at least 15 major and 50 minor glacial advances in Europe. • Hominids living in Europe and northern Asia were most affected by climatic oscillations. • As ice sheets expanded, the northern areas of Europe and Asia became uninhabitable. • As the climate warmed, migration routes such as the one from Central into Western Europe would have reopened.
Regions of Likely HominidOccupation • Dark areas are major glaciers. Arrows indicate likely migration routes.
Middle Pleistocene Hominids: Terminology • Major morphological changes relative to Homo erectus: • increase in brain size • more globular cranial vault • more vertical nose • reduction in the angulation of the occipit
Review of Middle Pleistocene Evolution (400,000-125,000 y.a.) • Like the erects/sapiens mix in Africa and China, fossils from Europe exhibit traits from both species. • Fossils from each continent differ, but the physical differences are not extraordinary. • There is a definite increase in brain size and a change in the shape of the skull.
Middle Pleistocene Tools • African and European archaics invented the Levallois technique for tool making. • Acheulian tools are associated with hand axes. • Different tool traditions coexist in some areas.
Settlements • People of the Mousterian culture lived in open sites, caves, and rock shelters. • Windbreaks of poles and skin were placed at the cave opening for protection against severe weather. • Fire was used for cooking, warmth, light, and keeping predators at bay.
Subsistence • Remains of animal bones demonstrate that Neandertals were successful hunters. • They used close-proximity spears for hunting (spear thrower and bow and arrow weren’t invented until the Upper Paleolithic). • Patterns of trauma in Neandertal remains match those of contemporary rodeo performers, indicating close proximity to prey.
Symbolic Behavior • Prevailing consensus has been that Neandertals were capable of articulate speech • Even if Neandertals did speak, they did not have the same language capabilities of modern Homo sapiens.
Burials • Neanderthals buried their dead. • Their burials included grave goods like animal bones and stone tools. • They placed the bodies of their dead in a flexed position.
Three Major Evolutionary Transitions • Transition from early Homo to H. erectus. Geographically limited to Africa and occurred rapidly. • Transition of H. erectus grading into early H. sapiens. Not geographically limited, but occurred slowly and unevenly. • Transition from Archaic H. sapiens to anatomically modern H. sapiens.
