Lithic technological responses to Late Pleistocene glacial cycling at Pinnacle Point Site 5-6, South Africa
There are multiple hypotheses for human responses to glacial cycling in the Late Pleistocene, including changes in population size, interconnectedness, and mobility. Lithic technological analysis informs us of human responses to environmental change because lithic assemblage characteristics are a reflection of raw material transport, reduction, and discard behaviors that depend on hunter-gatherer social and economic decisions. Pinnacle Point Site 5-6 (PP5-6), Western Cape, South Africa is an ideal locality for examining the influence of glacial cycling on early modern human behaviors because it preserves a long sequence spanning marine isotope stages (MIS) 5, 4, and 3 and is associated with robust records of paleoenvironmental change. The analysis presented here addresses the question, what, if any, lithic assemblage traits at PP5-6 represent changing behavioral responses to the MIS 5-4-3 interglacial-glacial cycle? It statistically evaluates changes in 93 traits with no a priori assumptions about which traits may significantly associate with MIS. In contrast to other studies that claim that there is little relationship between broad-scale patterns of climate change and lithic technology, we identified the following characteristics that are associated with MIS 4: increased use of quartz, increased evidence for outcrop sources of quartzite and silcrete, increased evidence for earlier stages of reduction in silcrete, evidence for increased flaking efficiency in all raw material types, and changes in tool types and function for silcrete. Based on these results, we suggest that foragers responded to MIS 4 glacial environmental conditions at PP5-6 with increased population or group sizes, 'place provisioning', longer and/or more intense site occupations, and decreased residential mobility. Several other traits, including silcrete frequency, do not exhibit an association with MIS. Backed pieces, once they appear in the PP5-6 record during MIS 4, persist through MIS 3. Changing paleoenvironments explain some, but not all temporal technological variability at PP5-6.Social Science and Humanities Research Council of Canada; NORAM; American-Scandinavian Foundation; Fundacao para a Ciencia e Tecnologia [SFRH/BPD/73598/2010]; IGERT [DGE 0801634]; Hyde Family Foundations; Institute of Human Origins; National Science Foundation [BCS-9912465, BCS-0130713, BCS-0524087, BCS-1138073]; John Templeton Foundation to the Institute of Human Origins at Arizona State Universit
Modeling the Past: The Paleoethnological Evidence
This chapter considers the earliest Paleolithic, Oldowan (Mode 1), and Acheulean (Mode 2)
cultures of the Old Continent and the traces left by the earliest hominids since their departure
from Africa. According to the most recent archaeological data, they seem to have followed two
main dispersal routes across the Arabian Peninsula toward the Levant, to the north, and the Indian
subcontinent, to the east. According to recent discoveries at Dmanisi in the Caucasus, the first
Paleolithic settlement of Europe is dated to some 1.75 Myr ago, which indicates that the first “out of
Africa” took place at least slightly before this date. The data available for Western Europe show
that the first Paleolithic sites can be attributed to the period slightly before 1.0 Myr ago. The first
well-defined “structural remains” so far discovered in Europe are those of Isernia La Pineta in
Southern Italy, where a semicircular artificial platform made of stone boulders and animal bones
has been excavated. The first hand-thrown hunting weapons come from the site of Scho¨ningen in
north Germany, where the first occurrence of wooden spears, more than 2 m long, has been
recorded from a site attributed to some 0.37 Myr ago. Slightly later began the regular control of
fire. Although most of the archaeological finds of these ages consist of chipped stone artifacts,
indications of art seem to be already present in the Acheulean of Africa and the Indian
subcontinent
Nothing Lasts Forever: Environmental Discourses on the Collapse of Past Societies
The study of the collapse of past societies raises many questions for the theory and practice of archaeology. Interest in collapse extends as well into the natural sciences and environmental and sustainability policy. Despite a range of approaches to collapse, the predominant paradigm is environmental collapse, which I argue obscures recognition of the dynamic role of social processes that lie at the heart of human communities. These environmental discourses, together with confusion over terminology and the concepts of collapse, have created widespread aporia about collapse and resulted in the creation of mixed messages about complex historical and social processes
