Investigating the peopling of North America through cladistic analyses of Early Paleoindian projectile points

The initial colonization of North America remains a controversial topic. There is widespread agreement that Clovis and related cultures of the Early Paleoindian period (∼11,500–10,500 BP) represent the first well-documented indications of human occupation, but considerable differences of opinion exist regarding the origins of these cultures. Here, we report the results of a study in which data from a continent-wide sample of Early Paleoindian projectile points were analyzed with cladistic methods in order to assess competing models of colonization as well as several alternative explanations for the variation among the points, including adaptation to local environmental circumstances, cultural diffusion, and site type effects. The analyses suggest that a rapidly migrating population produced the Early Paleoindian projectile point assemblages. They also suggest that the population in question is unlikely to have entered North America from either the Isthmus of Panama or the Midatlantic region. According to the analyses, the Early Paleoindians are more likely to have entered North America via either the ice-free corridor between the Laurentide and Cordilleran ice sheets that is hypothesized to have opened around 12,000 BP, or the Northwest Coast.     

Serpentine Hot Springs,Alaska: results of excavations and implications for the age and significance of northern fluted points

The dispersal of Homo sapiens across the New World is one of the greatest chapters in the history of our species; however, major questions about this late Pleistocene diaspora remain unanswered. Two contentious issues are the timing of colonization of the Bering Land Bridge and origin of Clovis, which at 13,000 calendar years ago is the earliest unequivocal complex of archaeological sites in temperate North America, known by its specialized fluted spear points. One hypothesis is that fluting technology emerged in Beringia and from there was carried southbound, with fluted points becoming the diagnostic “calling card” of early Paleoindians spreading across the Western Hemisphere. Fluted points have long been known from Alaska, yet until now they have never been found in a datable geologic context, making their relationship to Clovis a mystery. Here we show that a new archaeological site at Serpentine Hot Springs, Bering Land Bridge National Preserve, Alaska, contains fluted points in a stratified geologic deposit dating to no earlier than 12,400 calendar years ago. Our results suggest that Alaska's fluted-point complex is too young to be ancestral to Clovis, and that it instead represents either a south-to-north dispersal of early Americans or transmission of fluting technology from temperate North America. These results suggest that the peopling of the Americas and development of Paleoindian technology were much more complex than traditional models predict.     

Metapopulation Processes in the Long-Term Colonization of the Andean Highlands in South America

This paper analyses the importance of the South Central Andean High Puna megapatch, above 4000 masl, in the history of late Pleistocene exploration and colonization of the Atacama Desert, including the contrasting habitats that exist towards the hyperarid Pacific Ocean coast or the ecosystems bordering the tropical forests, on the western and eastern sides of the Andes, respectively. These ecosystems, which were firmly established by the end of the Pleistocene, are examined as key factors in the history of human peopling. The social, demographic and climate conditions associated with the peopling processes are discussed in relation to the appropriate technological, subsistence and settlement strategies developed by pioneer populations, who for their initial settlement selected highly productive patches where water and fauna converged. Based on concepts derived from metapopulation theory, all relevant archaeological paleoecological data from both sides of the Andean Cordillera are presented and discussed. It is concluded that the pioneer occupation of the high Puna megapatch was a gradual process, related to an emergent Andean human mobility system that connected a wide range of altitudinally staggered habitats. Moreover, we suggest that divergent cultural trajectories evolved since the early Holocene, affecting highland, lowland and coastal habitats.

     

The Upper Palaeolithic Lithic Industry of Nazlet Khater 4 (Egypt): Implications for the Stone Age/Palaeolithic of Northeastern Africa

Between Marine Isotope Stage (MIS) 4 and 2, Northeast Africa witnessed migrations of Homo sapiens into Eurasia. Within the context of the aridification of the Sahara, the Nile Valley probably offered a very attractive corridor into Eurasia. This region and this period are therefore central for the (pre)history of the out-of-Africa peopling of modern humans. However, there are very few sites from the beginning of the Upper Palaeolithic that document these migration events. In Egypt, the site of Nazlet Khater 4 (NK4), which is related to ancient H. sapiens quarrying activities, is one of them. Its lithic assemblage shows an important laminar component, and this, associated with its chronological position (ca. 33 ka), means that the site is the most ancient Upper Palaeolithic sites of this region. The detailed study of the Nazlet Khater 4 lithic material shows that blade production (volumetric reduction) is also associated with flake production (surface reduction). This technological duality addresses the issue of direct attribution of NK4 to the Upper Palaeolithic.     

The Archaeology of California

Stimulated by several important, recent empirical advances, California archaeologists are engaged in a series of lively debates. These advances include new discoveries about the early peopling of western North America and sustained occupation of the California coasts as early as 12–13,000 BP. There also have been significant new developments in the role of paleoenvironmental change in cultural evolution, the emergence of long-distance interaction spheres, the presence of intensive craft specializations, and the appearance of sociopolitically complex hunter–gatherers. This article addresses these issues—and several others—with a view to the general interests of scholars worldwide. The exceptional heterogeneity of California ecosystems (from deserts to dense redwood forests to bountiful offshore islands) and the remarkable cultural diversity exhibited by the dozens of major groups who made these lands their home combine to produce a complex indigenous sociopolitical picture. Current understandings reveal myriad trajectories of cultural change across nine major subregions of the state.     

Earliest hunters and gatherers of South America

Traditional syntheses of the archaeology of the late Pleistocene period in South America have focused primarily on the peopling of the continent by North American cultural groups and on identifying associations among regional sites. This focus has tended to ignore the widespread culture diversity of the period and the possible effects of different paleolandscapes on human migration and colonization, such as the presence of unglaciated tropical and temperate environments in the northern lowlands, the gateway to the interior. The earliest known cultural assemblages are characterized by various unifacial and bifacial lithic industries that may represent regional processes reminiscent of an Archaic lifeway. The major archaeological sites and associated artifact assemblages are examined in terms of regional and continental patterns of environmental and cultural change. Results suggest that the Pleistocene archaeological record of South America must be explained in its own terms and that the events and processes producing this record either occurred earlier than previously thought or are very different from those in North America.     

Pattern or bias? A critical evaluation of Midwestern fluted point distributions using raster based GIS

Because the abundance and distribution of fluted points has long played a critical role in interpreting various colonization and settlement scenarios of North America, correlations made between fluted point distribution and patterns of Early Paleoindian land use need to be critically evaluated. Gauging not just the source, but also nature of bias within distributional data of this sort is important if we are to improve the accuracy and reliability of our inferences concerning the timing, source, and mode of the radiation of human populations throughout the western Hemisphere. In this study, I employ a raster based GIS approach using a continuous non-site distribution of fluted biface distributions across a twenty-nine county (46,000 km²) study area of northern Illinois. The results suggest that when sources of bias are revealed and controlled for, significant settlement patterning can not only be identified, but more accurately interpreted.     

Google Earth, GIS and stone-walled structures in southern Gauteng, South Africa

In South Africa, air photos were used in the 1960s and 1970s to plot distribution maps of pre-colonial stone-walled structures in order to study the peopling of this landscape. Different architectural styles of stone-walled structures were attributed to different cultures, who shared a mixed agricultural and pastoralist economic base and a cattle centered world-view. New technologies such as Google Earth satellite imagery as well as Geographic Information System software justify revisiting these structures as they facilitate more complex analyses of larger databases. The spatial analysis of remotely sensed settlement data from the Suikerbosrand Nature Reserve near Johannesburg shows significant changes in settlement patterns from dispersed homesteads to nucleated towns during the last two or three centuries before colonial times. These changes echo similar patterns reported in the neighboring North West Province, where they have been interpreted as a sequence of evolution in social, political and economic complexity. In the Suikerbosrand reserve climate change, conflict and other factors may have helped bring about the observed changes in settlement patterns.     

Historians, prehistorians, and the tyranny of the historical record: Danish state formation through documents and archaeological data

Historians traditionally have viewed the emergence of Denmark as a nation-state through western European primary sources, inferring a fragmented, politically divided region between AD 800 and AD 1050. Conversely, archaeologists using local-scale, single-site data argue for unification by ca. AD 800. An alternative is offered, combiningregional-scale archaeological methods (rank-size analyses) and consideration of westernand northern European texts. This approach reveals that as disparate polities unified, the “homelands” of ruling dynasties came under control quickly, while peripheral areas remained largely autonomous. To incorporate peripheral areas, rulers manipulated the location and function of political and economic centers. Local resistance to change is reflected in slow, uneven unification, interregional elite competition, and eventually, armed rebellion. The apparent discrepancies between historic and prehistoric data are no error; in fact, they mirror the inherent conflicts of this profound social transformation.     

The relationship of the Mimbres to other southwestern and Mexican populations

Previous aDNA research in the Southwest provides a framework to understand the Mimbres population which maintains a unique identity in the archeology of the desert Southwest of North America. Both the mitochondrial DNA (mtDNA) haplogroups and haplotypes of a sample of 46 Mimbres individuals were identified from skeletal remains and compared to those of other ancient and modern populations in the American Southwest and Mexico. The haplogroup frequency distribution of the Mimbres resembles that of other Southwestern populations, suggesting a close relationship between the Mimbres and the neighboring populations and population continuity for a long period of time. However, their relatively low frequency of haplogroup A (11% n = 5) is consistent with a clinal distribution of haplogroup A from Mesoamerica to the Southwest. Moreover, unlike other Southwestern populations, the Mimbres share haplotypes with populations to the south, such as the Cora, Huichol, and Nahua, suggesting gene-flow from Mesoamerica. Here we discuss this data in light of the origin of the Mimbres population and their relationship to other Southwestern and Mexican populations.     

REVISITING PLATFORM MOUNDS AND TOWNHOUSES IN THE CHEROKEE HEARTLAND: A COLLABORATIVE APPROACH

Abstract

This article describes the development and initial results of the Western North Carolina Mounds and Towns Project, a collaborative endeavor initiated by the Tribal Historic Preservation Office of the Eastern Band of Cherokee and the Coweeta Long Term Ecological Research Program at the University of Georgia. The goal of this project is to generate new information about the distribution of late prehistoric mounds and historic period townhouses in western North Carolina. This ongoing research has produced updated location and chronological data for 15 Mississippian period mounds and historic Cherokee townhouses, and led to the discovery of a possible location for the Jasper Allen mound. Using these new data, I suggest that David Hally's model for the territorial size of Mississippian polities provides a useful framework for generating new research questions about social and political change in western North Carolina. I also posit that the cultural practice of rebuilding townhouses in place and on top of Mississippian period platform mounds, a process that Christopher Rodning describes as “emplacement,” was common across western North Carolina. In terms of broader impacts, this project contributes positively to the development of indigenous archaeology in the Cherokee heartland.     

Stable isotopic analysis of human and faunal remains from the Incipient Chulmun (Neolithic) shell midden site of Ando Island,Korea

We analyzed stable carbon and nitrogen isotope ratios of human and animal remains from the Ando shell midden, South Korea. The Ando site is a rare Incipient Chulmun (Neolithic) site (ca. 6000–5000 BC), which contains well-preserved human and animal bones in shell mounds. The stable isotope results for humans (average δ¹³C = −13.5 ± 0.5‰ and δ¹⁵N = 15.2 ± 0.5‰) indicate that Ando people in the Incipient Chulmun period strongly depended on marine resources. There were no isotopic differences between humans of different sex and age at this site. We compared our data with other previous published isotopic data from the Chulmun sites and found that the Ando people had similar isotope values to the southern Chulmun people (Tongsamdong and Daepo), but different isotopic ratios than the western Chulmun people (Daejukri and Konamri). These results indicate that marine foods were the main food resources in the southern coastal regions, but not in the western coastal regions in Chulmun Korea.     

Economic growth and restructuring in Canada's heartland and hinterland: From shift‐share to multifactor partitioning

The geography of the Canadian economy has long been dominated by heartland‐hinterland contrasts, with manufacturing identified as the dominant function of most heartland cities in analyses of the 1961 and 1971 census data. However, the proportion of employment in manufacturing has been declining in the heartland provinces of Ontario and Quebec over the past fifty years and some geographers argue that the heartland‐hinterland dimension of the regional economy is being overridden by city‐regions that are integrated into global networks of production and trade. The heartland‐hinterland trends are examined using multifactor partitioning (MFP), an advanced shift‐share methodology, for the period of 2001–2006. This is the first intercensal period in which Canadian business has faced the full impact of the removal of North American tariff protection and the increased globalization of the Canadian economy. The data covers employment by eighteen industry sectors for the seventy‐three economic regions defined by Statistics Canada. MFP measures the region and industry‐mix effects, which are interpreted as in the traditional shift‐share model (though they are derived more accurately) and, in addition, an interaction effect. The results demonstrate that the broad heartland‐hinterland differences in the distribution of population and employment growth are increasing not decreasing and that the hinterland is in fact falling further behind the heartland in employment growth. However the Calgary‐Edmonton corridor and the Lower Mainland of British Columbia are emerging as a western heartland. The population size of cities does affect their rates of employment growth, but so too does their location: the growth of heartland cities is outpacing those in the hinterland. The Appendix provides the equations for two‐variable multifactor partitioning.     

Refuting the technological cornerstone of the Ice-Age Atlantic crossing hypothesis

The “North Atlantic Ice-Edge Corridor” hypothesis proposes that sometime during the Last Glacial Maximum, roughly 26,500–19,000 years ago, human populations from southern France and the Iberian Peninsula made their way across the North Atlantic and colonized North America. A key element of that hypothesis is the apparent similarity between stone-tool-production techniques of Solutrean peoples of Western Europe and Clovis and purportedly pre-Clovis peoples of eastern North America, most especially the supposed intentional use of “controlled overshot flaking,” a technique for thinning a bifacial stone tool during manufacture. Overshot flakes, struck from prepared edges of the tool, travel across the face and remove part of the opposite margin. Experimental and archaeological data demonstrate, however, that the most parsimonious explanation for the production of overshot flakes is that they are accidental products created incidentally and inconsistently as knappers attempt to thin bifaces. Thus, instead of representing historical divergence, overshot flakes in Clovis and Solutrean assemblages mark convergence in the use of the same simple solution for thinning bifaces that produced analogous detritus.     

The Epipaleolithic (Iberomaurusian) from Grotte des Contrebandiers,Morocco

First identified 100 years ago, the Iberomaurusian is an Epipaleolithic industry that was described from a number of sites across western North Africa. One of these is Grotte des Contrebandiers (Smugglers’ Cave) in Morocco, where Abbé Jean Roche recovered Iberomaurusian materials in excavations in the late 1950s. Although the lithics were published in the early 1960s, subsequent changes in methods and in assessing the interpretive potential of lithic assemblages necessitated a restudy of these collections from Contrebandiers. This study led to a better understanding of the lithic types present and of the use of particular stone raw materials. Iberomaurusians emphasized lithic strategies that maximized use of fine-grained stone to the extent that pièces esquillées should be, among others, a defining criterion for this lithic industry.     

History,Chronology and Techno-Typology of the Upper Paleolithic Sequence in the Shuidonggou Area,Northern China

The timing and behavioral markers of the Upper Paleolithic in different parts of the world are of great importance to research on modern human dispersals. The pattern of behavioral developments in the Upper Paleolithic in northern China differs in important ways from the patterns observed in West Eurasia, Africa, and South Asia. Shuidonggou (SDG), a cluster of Paleolithic sites in northern China, contains several of the most important Upper Paleolithic sites in the region. Various localities yield evidence of three major cultural components dated by ¹⁴C, uranium-series, and optically stimulated luminescence (OSL) methods to between roughly 46 ka and 10 ka. The oldest component, blade assemblages with western Eurasian early Upper Paleolithic characteristics, appears to be intrusive from Siberia and/or Mongolia, beginning at least 41 ka (e.g., SDG 1 and SDG 9). Advanced core and flake assemblages may mark the appearance of an indigenous Late Paleolithic of North China beginning at around 33 ka (e.g., SDG 2 and SDG 8). Finally, around 10.5 ka, microblade technology arrived in the area (SDG 12), although we are not sure of its origins at present. Other typical Upper Paleolithic cultural remains, such as bone tools and body decorations, have been found at various localities in the SDG area as well (e.g., ostrich eggshell beads from SDG 2, 7, and 8). Information from this cluster of occupations increases our understanding of cultural variability, adaptation, and demographic dynamics of modern humans in Late Pleistocene northern Asia.

     

The origins of agriculture in North-West Africa: macro-botanical remains from Epipalaeolithic and Early Neolithic levels of Ifri Oudadane (Morocco)

This research aims to shed light on the early stages of agricultural development in Northern Africa through the analysis of the rich macro-botanical assemblages obtained from Ifri Oudadane, an Epipalaeolithic–Early Neolithic site from North-East Morocco. Results indicate the presence of domesticated plants, cereals (Hordeum vulgare, Triticum monococcum/dicoccum, Triticum durum and Triticum aestivum/durum) and pulses (Lens culinaris and Pisum sativum) in the Early Neolithic. One lentil has been dated to 7611 ± 37 cal BP representing the oldest direct date of a domesticated plant seed in Morocco and, by extension, in North Africa. Similarities in both radiocarbon dates and crop assemblages from Early Neolithic sites in Northern Morocco and the Iberian Peninsula suggest a simultaneous East to West maritime spread of agriculture along the shores of the Western Mediterranean. Wild plants were abundantly collected in both the Epipalaeolithic and the Early Neolithic periods pointing to the important role of these resources during the two periods. In addition to fruits and seeds that could have been consumed by both humans and domesticated animals, fragments of esparto grass (Stipa tenacissima) rhizomes have been identified. This is a western Mediterranean native plant that may have been used as a source of fibres for basketry.

COLONIZING CONTRASTING LANDSCAPES. THE PIONEER COAST SETTLEMENT AND INLAND UTILIZATION IN SOUTHERN NORWAY 10,000–9500 YEARS BEFORE PRESENT

This article contributes a western Scandinavian perspective to the discussion of the human colonization of former glaciated landscapes. Four assumptions concerning the peopling of the Norwegian coast are discussed: 1) a delayed colonization, 2) an immigration from the ‘North Sea Continent’, 3) reindeer as the main economic factor, and 4) a rapid rate of expansion along the coast. It is argued that only the first and last suppositions still appear credible, but need to be confirmed. A gradual major development is evident. Stage 1: Marine hunters colonized the resource‐rich coastlines of south‐west Sweden and southern Norway about 10,000 y.BP. Stage 2: Soon after, based on short seasonal moves, some coastal groups started exploiting reindeer in recently deglaciated mountain areas in south‐west Norway. A similar subsistence pattern developed in north‐west Norway. With its remote location, distinct landscape development and many‐faceted environments, Norway appears as ideal for exploring human colonization processes on different geographical scales. More C14‐dates and osteological material are, however, still needed.     

The British Late Middle Palaeolithic: An Interpretative Synthesis of Neanderthal Occupation at the Northwestern Edge of the Pleistocene World

The British Middle Palaeolithic is divided into two discrete periods of occupation: the Early Middle Palaeolithic (MIS 9–7, ~330–180 ka BP) and the Late Middle Palaeolithic (MIS 3, ~59–36 ka BP), separated by a long hiatus. Owing to the relative poverty of the record and historical difficulties in dating and correlating archaeological sites, the British Late Middle Palaeolithic has, until recently, received scant attention, and has largely been regarded as the poor man of Europe, especially by British archaeologists. Indeed, there has been more discussion of the absence of humans from Britain than of what they did when they were present. We aim here to redress that situation. Following from recent considerations of the Early Middle Palaeolithic (White et al. in J. Quat. Sci. 21:525–542, 2006; Scott, Becoming Neanderthal, Oxbow, Oxford, 2010), we offer an interpretative synthesis of the British Late Middle Palaeolithic, situating ‘British’ Neanderthals in their chronological, environmental and landscape contexts. We discuss the character of the British record, and offer an account of Neanderthal behaviour, settlement systems and technological practices at the northwestern edge of their known Upper Pleistocene range. We also examine the relationship of the enigmatic Early Upper Palaeolithic leafpoint assemblages to Neanderthals.
