4
The Pleistocene
  • The Pleistocene, often called the Ice Age, was
    marked by advances and retreats of massive
    continental glaciations.
  • At least 15 major and 50 minor glacial advances
    have been documented in Europe.
  • Hominids were impacted as the climate, flora, and
    animal life shifted.
  • Middle Pleistocene (780,000 25,000 y.a.)
  • Upper Pleistocene (125,00010,000 y.a.)

5
Interglacials
  • Climatic intervals when continental ice sheets
    are retreating, eventually becoming much reduced
    in size.
  • Interglacials in northern latitudes are
    associated with warmer temperatures, while in
    southern latitudes the climate becomes wetter.

6
Glaciations
  • Climatic intervals when continental ice sheets
    cover much of the northern continents.
  • Glaciations are associated with colder
    temperatures in northern latitudes and more arid
    conditions in southern latitudes, most notably in
    Africa.

Key Middle Pleistocene Premodern Human (H.

18
Crania from China
  • (a) Dali skull and (b) Jinniushan skull, both
    from China.
  • These two crania are considered by some to be
    Asian representatives of Homo heidelbergensis.

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.

21
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.

22
The Levallois Technique
23
Culture of Neandertals
  • Neandertals, who lived in the cultural period
    known as the Middle Paleolithic, are almost
    always associated with the Mousterian industry.
  • In the early part of the last glacial period,
    Mousterian culture extended across Europe and
    North Africa into the former Soviet Union,
    Israel, Iran, and as far east as Uzbekistan and
    perhaps even China.

24
Culture of Neandertals
  • Neandertals improved on previous prepared-core
    techniques by inventing a new variation.
  • They trimmed a flint nodule around the edges to
    form a disk-shaped core.
  • Each time they struck the edge, they produced a
    flake, continuing this way until the core became
    too small and was discarded.
  • They then trimmed the flakes into various forms,
    such as scrapers, points, and knives.

Mousterian Tools
29
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.

30
Excavation of the Tabun Cave, Mt. Carmel, Israel
31
Shanidar 1
  • Among the individuals buried at Shanidar cave is
    the skeleton of a one-armed, partially blind,
    crippled man.
  • He could not have hunted or gathered food on his
    own.
  • Some believe his survival is proof of Neandertal
    compassion and humanity

32
Subsistence
  • Remains of animal bones demonstrate that
    Neandertals were successful hunters.
  • Used close-proximity spears for hunting (spear
    thrower and bow and arrow werent invented until
    the Upper Paleolithic).
  • Patterns of trauma in Neandertal remains match
    those of contemporary rodeo performers,
    indicating close proximity to prey.

33
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.

34
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.

35
Question
  • The prevailing consensus among researches is that
    Neandertal
  • was capable of articulate speech.
  • probably used grunting sounds to communicate.
  • did not have the anatomical features required for
    speech.
  • was unable to speak.

36
Answer a
  • The prevailing consensus among researches is that
    Neandertal was capable of articulate speech.

37
Question
  • Regarding deliberate burials
  • Neandertals laid the deceased on their back.
  • Neandertals included stone tools.
  • Neandertals included a shroud.
  • it is seen in Africa before Europe.

38
Answer b
  • Regarding deliberate burials Neandertals included
    stone tools.

Cultural Contrasts Neandertals and Upper
Paleolithic Modern Humans
Neandertals Upper Paleolithic Modern Humans
ToolTechnology Numerous flake tools few, however, apparently for highly specialized functions use of bone, antler, or ivory very rare relatively few tools with more than one or two parts Many more varieties of stone tools many apparently for specialized functions frequent use of bone, antler, and ivory many more tools comprised of two or more component parts
41
Cultural Contrasts Neandertals and Upper
Paleolithic Modern Humans
Neandertals Upper Paleolithic Modern Humans
Hunting Efficiency and Weapons No long-distance hunting weapons close-proximity weapons used (more likelihood of injury) Use of spear-thrower and bow and arrow wider range of social contacts, permitting more organized hunting parties
Stone Material Transport Stone materials transported only short distances Stone tool raw materials transported over longer distances, implies wider social networks and trade

Art Artwork uncommon small mostly of a personal nature some items misinterpreted as art others may be intrusive from overlying Upper Paleolithic contexts cave art absent Artwork much more common, including transportable objects as well as elaborate cave art well executed,using a variety of materials and techniques stylistic sophistication

Burial Deliberate burial at several sites graves unelaborated graves frequently lack artifacts Burials much more complex, frequently including both tools and remains of animals

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.
