Understanding Premodern Humans
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.
Changing Pleistocene Environments in Africa
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.
Mousterian Tools
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
1. Transition from early Homo to H. erectus. Geographically limited to Africa and occurred rapidly.
2. Transition of H. erectus grading into early H. sapiens. Not geographically limited, but occurred slowly and unevenly.
3. Transition from Archaic H. sapiens to anatomically modern H. sapiens.
