A Neutral Model of Stone Raw Material Procurement

Abstract: Stone, tool assemblage variability is considered a reliable proxy measure of adaptive variability. Raw material richness, transport distances, and the character of transported technologies are thought to signal (1) variation in raw material selectivity based on material quality and abundance, (2) optimization of time and energy costs associated with procurement of stone from spatially dispersed sources, (3) planning depth that weaves raw material procurement forays into foraging activities, and (4) risk minimization that sees materials transported in quantities and forms that are energetically economical and least likely to fail. This paper dispenses with assumptions that raw material type and abundance play any role in the organization of mobility and raw material procurement strategies. Rather, a behaviorally neutral agent-based model is developed involving a forager engaged in a random walk within a uniform environment. Raw material procurement in the model is dependent only upon random encounters with stone sources and the amount of available space in the mobile toolkit. Simulated richness-sample size relationships, frequencies, of raw material transfers as a function of distance from source, and both quantity-distance and reduction intensity-distance relationships are qualitatively similar to commonly observed archaeological patterns. In some archaeological cases it may be difficult to reject the neutral model. At best, failure to reject the neutral model may mean that intervening processes (e.g., depositional time-averaging) have erased high-frequency adaptive signals in the data. At worst, we may have to admit the possibility that Paleolithic behavioral adaptations were sometimes not responsive to differences between stone raw material types in the ways implied by current archaeological theory.

Geophysical surveys as landscape archaeology

Abstract: Recent advances in technology and practice allow geophysical surveys in archaeology to produce maps of subsurface features over large areas and in potentially great detail. It is shown through a series of case studies from two regions in North America that archaeo-geophysical surveys can produce primary information suitable for the study of site content, structure and organization, for examining spatial patterns and relationships, and for directly confronting specific questions about a site and the past. Because large buried cultural landscapes can now be revealed, it is argued that an alternative perspective on regional or landscape archaeology may be possible because space can be viewed in terms of tens of hectares as opposed to the tens of square meters typical of archaeological excavations. Moreover, by placing focus on such buried features as dwellings, storage facilities, public structures, middens, fortifications, trails, or garden spaces that are not commonly revealed through most contemporary surface inspection methods, a richer view of archaeology, the past, and cultural landscapes can be achieved. Archaeo-geophysical surveys can also play an important role in Cultural Resource Management (CRM) contexts as feature discovery tools for focusing expensive excavations, thereby reducing the amount needed and lowering costs. Their utility is weighed against shovel test pits as a primitive and costly form of prospecting.

Setting Theoretical Egos Aside: Issues and Theory in North American Archaeology

Abstract: Theory in North American archaeology is characterized in terms of foci and approaches manifested in research issues, rather than in explicit or oppositional theoretical positions. While there are some clear-cut theoretical perspectives—evolutionary ecology, behavioral archaeology, and Darwinian archaeology—a large majority of North American archaeology fits a broad category here called “processual-plus.” Among the major themes that crosscut many or all of the approaches are interests in gender, agency/practice, symbols and meaning, material culture, and native perspectives. Gender archaeology is paradigmatic of processual-plus archaeology, in that it draws on a diversity of theoretical approaches to address a common issue. Emphasis on agency and practice is an important development, though conceptions of agency are too often linked to Western ideas of individuals and motivation. The vast majority of North American archaeology, including postprocessual approaches, is modern, not postmodern, in orientation. The relative dearth of theoretical argument positively contributes to diversity and dialogue, but it also may cause North American theory to receive inadequate attention and unfortunate misunderstandings of postmodernism.

Lithic Source Use and Paleoarchaic Foraging Territories in the Great Basin

Abstract: Paleoarchaic (11.5–8.0 ka) occupants of the Great Basin encountered numerous lithic sources as they moved across foraging territories. Source provenance and lithic technologic analyses applied to the tools manufactured from these source materials elucidate several aspects of mobility, including the geographic scale of material conveyance and extent and possible routes of population movement. This research indicates that central Great Basin groups traversed large subsistence territories, extending more than 400 km from north to south, with mobility tactics probably keyed to the distribution of resource-rich wetlands. Changes in source representation parallel warming and drying trends, suggesting that Paleoarchaic foraging ranges shifted as wetlands diminished after about 9.5–8.5 ka.

Cultural evolution and stochastic network growth

Abstract: Archaeological theory has traditionally presupposed the existence of "battleship curves" in stylistic evolution, with little understanding about what governs the width (variant frequency) or length (variant lifespan) of these curves. In terms of these variables. we propose that there is a testable difference between independent decisions, unbiased transmission, and biased transmission in cultural evolution. We expect independent decision making to be represented by an exponential distribution of variant prevalence in the population. In contrast, unbiased transmission tends to be characterized by a power law or log-normal distribution of prevalence, while biased transmission should deviate significantly from the unbiased case. The difference between these categories may be fundamental to how cultural traits spread and persist. In order to make analytical predictions for unbiased transmission, we adapt a model of stochastic network growth that, by quantitatively demonstrating the inherent nonlinearity at unbiased transmission, can explain why a few highly popular styles can be expected to emerge in the course of cultural evolution. For the most part, this model predicts the frequencies of pottery decorations remarkably well over a 400-year span of Linearbandkeramik settlement in the Merzbach valley. Because the highest frequencies of actual motifs are somewhat less than predicted by our unbiased transmission model, we identify an anti-conformist, or pro-novelty, bias in the later phases of the Neolithic Merzbuch Valley.

Clovis hunting strategies, or how to make out on plentiful resources

Abstract: Traditionally, hunter-gatherers of the Clovis period have been characterized as specialized hunters of large terrestrial mammals. Recent critiques have attempted to upend this position both empirically and theoretically, alternatively favoring a more generalized foraging economy. In this paper, the distinction between subsistence specialists and generalists is framed in terms of forager selectivity with regards to hunted prey, following a behavioral ecological framework. Faunal data are compiled from 33 Clovis sites and used to test the two alternative diet-breadth hypotheses. The data support the older “Clovis as specialist” model, although some use of small game is apparent. Furthermore, data from modern hunter-gatherers are marshaled to support the theoretical plausibility of specialized large-mammal hunting across North America during the Late Pleistocene.

Social practice, method, and some problems of field archaeology

Abstract: This article argues that the development of excavation field methods in archaeology is closely tied to the social position of fieldworkers. We also note disaffection in field contract archaeology today resulting from a wide range of factors, including the separation of excavation from interpretation. We argue that this separation and the notion that archaeological excavation can be seen as unskilled undermine the scientific basis of archaeology. A reflexive archaeology is discussed that empowers field archaeology by (a) focusing interpretation at the trowel's edge, (b) bringing multiple perspectives close to the moment of excavation, and (c) documenting the documentation process.

Ceramic Standardization and Intensity of Production: Quantifying Degrees of Specialization

Abstract: The aim of this study is to examine the relationship between metric variability of ceramic vessels of a single type and intensity of production. This relationship is examined on the basis of vessels made by Indian and Spanish potters whose rates of production vary from low to high. Results are compared with Filipino data to embrace different cultures and therefore possibly different emic conceptions of standardization. We conclude that rate of production affects the degree of standardization. However, only in a high-rate production situation do we have motor habits that transcend emic conceptions of standardization. Indeed, factors like size classes, emic conception of size classes, and skill may induce a certain variability despite similar rates of production. Indexing degrees of standardization needs, in other respects, to take into account the cumulative effect of production events that play on the CV (Coefficient of Variation) values. Applied to Mesopotamian data, our results suggest that third millennium ceramic production can be compared to low-rate production observed ethnographically.

Resettled farmers and the making of a Mississippian polity

Abstract: Population displacement, resettlement, and migration constitute important dimensions in a general process of “cultural construction.” A pedestrian survey and extensive excavations of 255 domestic buildings and related artifacts at 15 contemporaneous sites document a pattern of localized resettlement in which thousands of agricultural villagers moved or were displaced coeval with the founding of Cahokia. The resettled villagers appear to have moved into a previously unoccupied upland zone that surrounds the Mississippi River floodplain. Identified as the “Richland Complex,” the seemingly abrupt resettlement corresponds to other regional evidence of demographic reconfiguration and cultural pluralism. The immediate effect of this study is a reorientation of research at Cahokia toward the goals of a “historical-processual“ archaeology.

End scraper reduction and hunter-gatherer mobility

Abstract: Various lithic measures have been invoked to argue that human foragers moved over greater or lesser distances, or moved with greater or lesser frequency when compared with other foraging groups. This paper examines one of those measures—the reduction of blade end scrapers from early Upper Paleolithic Aurignacian and Perigordian occupations in southwestern France. Evidence of end scraper reduction is compared with faunal diversity and lithic material provenience, the former a potential catalyst of and the latter a potential reflection of mobility. A relationship between less-intense end scraper reduction, somewhat elevated percentages of distant raw materials, and reindeer-dominated fauna is noted during cold and apparently open environmental conditions. Less consistency in the extent of end scraper reduction is observed among assemblages associated with more diverse and at times less-mobile fauna. These observations argue for the importance of a fine-grained comparison of lithic and other data, the complexity of procurement strategies, and the recognition that greater or lesser reduction does not translate directly into greater or lesser mobility.

Beyond the Margin: American Indians, First Nations, and Archaeology in North America

Abstract: In North America, American Indians and First Nations have often been at odds with archaeologists over the status of their relationships, about who should have control over research designs and research questions, the interpretation of information about past cultures, and the ways past cultures are represented in the present. While the influence of the voice of Indigenous Nations in the discipline has risen, in many ways their voices are as stifled now as they were in the 1960s. This paper gives an American Indian perspective on the current practice of archaeology in North America and offers suggestions for improving relationships.

Patterns of elite faunal utilization at Moundville, Alabama

Abstract: In recent years, zooarchaeological research has begun to examine the roles of animals as part of the suite of symbols employed in the ongoing social, ceremonial, and political dynamics of prehistoric cultural systems. In the southeastern United States, studies of late prehistoric Mississippian chiefdoms have documented differences in species composition and meat cuts associated with particular social contexts of consumption—for instance, ceremonial feasting vs. private meals—and also with gross distinctions in social rank—elite vs. commoner. Differences in the latter reflect elite control of procurement as well as cultural rules that assign meanings to certain species, which in so doing regulates access to their consumption. Faunal samples collected by recent mound excavations at the Moundville site in west-central Alabama provide the basis for an examination of more subtle differences in the consumption patterns of elite residents. Zooarchaeological samples produced by two elite households, although generally similar and fitting expectations for elite consumption well, are distinguished by differences in the distribution of rare species, the role of fish, and possibly by evidence of differences in food waste, distinctions that can be associated with interpretations of these households' relative status in Moundville society drawn from other classes of archaeological data.

Showing off, Foraging Models, and the Ascendance of Large-Game Hunting in the California Middle Archaic

Abstract: In a recent paper in American Antiquity (2002:231-256), Hildebrandt and McGuire argue that archaeofaunal patterns in California document an ascendance of artiodactyl hunting during the Middle Archaic. They also suggest that such a trend is inconsistent with predictions derived from optimal-foraging models. Given the apparent failure of foraging theory, they advance a “showing off” model of large-game hunting. While their presentation is intriguing, we do not see a theoretical warrant for predicting that show-off hunting would have increased during the Middle Archaic. We present here an alternative hypothesis for the increase in artiodactyl abundances and the hunting-related patterns they identify. That hypothesis follows directly from the prey model itself under what appears to have been a dramatic artiodactyl population expansion after the drought-dominated middle Holocene period.

Consolidation and hierarchy: Chiefdom variability in the Mississippian Southeast

Abstract: Explaining variability among Mississippian period (A.D. 1000-1600) chiefdoms has become a key research aim for archaeologists in the southeastern United States. One type of variability, in which simple and complex chiejdoms are distinguished by the number of levels of regional hierarchy, has dominated chiefdom research in this part of the world. The simple-complex chiefdom model is less applicable to the Mississippian Southeast, however, as there is little empirical evidence that chiefdotus here varied along this quantitative dimension. This article offers a qualitative model in which regional hierarchies are distinguished hy the manner in which authority is ceded or delegated between an apical or regional chief and constituent community-level leaders; chiefly power may he ceded from local-level leaders upward to the regional chief, or delegated from the regional chief downward to local leaders. This apical-constituent model addresses variation in the administrative structures of chiefdoms: it is not a chiefdom typology. The model is used to contrast two Mississippian polities, Moundrille in west-central Alabama and Powers Fort in southeastern Missouri, and illustrates variability in the process by which local communities were integrated into regional institutions.

Phytolith evidence for early maize (Zea mays) in the Northern Finger Lakes Region of New York

Abstract: The timing of crop introductions, particularly of maize (Zea mays), has been of long-standing interest to archaeologists working in various regions of eastern North America. The earliest confirmed macrobotanical evidence for maize in New York is A.D. 1000. We report on the results of accelerator mass spectrometer (AMS) dating. phytolith analysis, and stable carbon isotope analysis of carbonized cooking residues adhering to the interior surface of pottery sherds from three sites in the northern Finger Lakes region of New York. Maize, squash (Cucurbita sp.) wild rice (Zizania aquatica), and sedge (Cyperus sp.) were identified in phytolith assemblages dating to as early as the first half of the calibrated seventh century A.D. The results demonstrate that low δ 13 C values on cooking residues cannot be used to preclude the possibility that maize was cooked in vessels. Two of the maize-bean-squash crop triad were present in New York at least 350 years earlier than previously documented, and the Northern Flint Corn Complex was present in New York by at least the first half of the seventh century A.D. This research highlights the potential of cooking residues to provide new insights on prehistoric plant-based subsistence.

The theoretical landscape and the methodological development of archaeology in Latin America

Abstract: Latin American archaeology has been influenced by the world theoretical context, from which it has developed original approaches. Currently, a culture-history conceptual foundation still predominates in the region, with some modern variants that have emphasized environmental aspects and approached specific problems. Processual archaeology, especially the North American varieties, remains minor in the region despite many Latin American archaeologists' belief that their work falls within this camp. Post-processual trends are even less well represented, although a growing number of researchers focus in an eclectic fashion on subject matter that corresponds to the post-processual agenda (e.g., identity, multivocality, etc.). Researchers in certain areas within the region are producing original research linked to political economy and its relation to ideology, and others are focusing on symbolic and cognitive aspects (in some cases within a structuralist framework). In Latin America several interesting methodological developments are emerging, among which ethnoarchaeology and vertebrate taphonomy stand out. In recent years historical archaeology has been one of the disciplines that has grown the most and achieved the greatest popularity. Despite the still-limited nature of Latin American archaeology's contributions in the field of theory and methodology, there is nonetheless sustained growth in this direction, fundamentally in the generation of models for the interpretation of regional processes. However, these contributions are not visible at the level of international debate and are generally ignored by archaeologists from the central countries. The multiple causes of this phenomenon are analyzed.

The sourcing and interpretation of Cahokia-style figurines in the Trans-Mississippi south and southeast

Abstract: Exchange of preciosities is often considered an integral factor in the emergence of Mississippian chiefdoms, and the rise of Cahokia has been linked to such long-distance trade. We know that Cahokia was the center of production for large flint clay figurines and effigy pipes (Emerson and Hughes 2000). Similar Cahokia-style figures have been found in the Trans-Mississippi South and the Southeast. We investigated the material used.to make these figures using a newly developed nondestructive PIMA SP™ spectroscopic technology to identify the stone and to determine their source location. These analyses proved that the figures were made of Missouri flint clay from quarries near St. Louis. We submit that Cahokia was the twelfth-century source for the production of these Cahokia-style figures. Outside of Cahokia the flint clay figures were primarily found in Caddoan mortuaries, reinforcing earlier evidence of a strong Cahokia-Caddoan connection. The available chronological and contextual information indicates the flint clay figures left Cahokia after it began to decline in the late thirteenth-century, through various mechanisms of extra-local exchange rather than as part of any systematic prestige-goods network. The association of these highly symbolic figures with Cahokia allows us to reevaluate the indigenous iconography and propose that many of the themes (e.g., fertility and warfare) that later appear in Eastern Woodlands native cosmology such as the Southeastern Ceremonial Complex were first codified here in the twelfth-century.

New Interpretations of Mimbres Public Architecture and Space: Implications for Cultural Change

Abstract: Recent excavations and reanalysis of existing data on communal pit structures provide intriguing insights into ritual and cultural developments over a period of about 350 years, from A.D. 800 to 1140, in the Mimbres Valley of southwestern New Mexico. In the middle of this period, people shifted dwellings from pithouses to pueblos, a shift previously viewed as the pivotal transformation of Mimbres society. In this paper we show that significant changes in Mimbres society began in the A.D. 800s. Trends in the construction methods of communal pit structures, the placement of dedicatory items within them, their ritual retirements, and their long-lived significance within Mimbres villages, reflect other changes that occurred in Mimbres society. We contend that in the A.D. 800s, rapid change based on strong connections with the Hohokam of southern Arizona and agricultural intensification began a trajectory that culminated in the Classic Mimbres pueblos of the A.D. 1000s and early 1100s.

The death of Owasco

Abstract: The Owasco culture is a critical taxon in William A. Ritchie's culture history of New York. In its final construction, Owasco was viewed by Ritchie as representing the onset of recognizable northern Iroquoian traits. This interpretation is widely accepted among archaeologists currently working in New York. An examination of the history of the taxon shows that it is nothing more than a subjectively defined unit based on the thoughts of Ritchie and his predecessor Arthur C. Parker. Recent empirical research has shown that the key traits Ritchie used to define Owasco have very different histories than he thought. Owasco does not stand either theoretically or empirically and should be abandoned as a unit of analysis.

Modifying Pottery and Kivas at Chaco: Pentimento, Restoration, or Renewal?

Abstract: Patterns of use of ceramic objects and masonry architecture at Chaco Canyon in the southwestern United States indicate refurbishing of some vessels and architectural forms. Ceramic cylinder jars show evidence for obliteration of earlier designs and subsequent repainting and refiring of new designs. Communal structures, or kivas, were dismantled and rebuilt. Three possible explanations for these patterned are explored: revision of errors, restoration of worn surfaces, or ritual renewal. Renewal appears the most likely explanation for most of the patterning seen, providing a fuller picture of Chacoan ritual life and beliefs. Implications for research in the Chaco area and greater Southwest are discussed.

Documenting prehistoric communication networks: A case study in the Paquimé polity

Abstract: Hilltop features reported around the site of Paquime, the political center of a prehistoric complex polity in northwest Chihuahua, Mexico, have been interpreted as a fire-signaling network by archaeologists. If these hilltop platform features functioned as such a communication system, it provides important information for our interpretation of regional integration and interaction for the Paquime polity. This paper reports the results of a survey of hilltops in the area and a subsequent GIS-based Intervisibility analysis, which determined that a series of hilltop platforms in the region were ideally situated for fire.signaling purposes. I discuss the need for implementing tests for intervisibility and tests for determining the significance of that intervisibility, and then consider some implications of the Paquime fire-signaling system on sociopolitical organization and integration.

Large-Game Hunting, Gender-Differentiated Work Organization, and the Role of Evolutionary Ecology in California and Great Basin Prehistory: A Reply to Broughton and Bayham

Abstract: We are pleased that Broughton and Bayham acknowledge that there was an increase in large-game hunting during the Middle Archaic (ca. 4000-1000 B.P.) in California and the Great Basin that reached proportions greater than any other interval during the Holocene. They argue, however, that this was simply the result of changing climatic conditions, and that the larger social context of hunting plays little or no role in this development. The following discussion identifies several weaknesses in their environmental determinism, and shows how a more comprehensive analysis of genders differentiatedfitness and work organization provides greater explanatory power than the narrow, fauna-based approach they advocate.

Archaic Period Canoes from Newnans Lake, Florida

Abstract: Low lake levels, due to drought in spring and summer 2000, revealed the decayed remnants of over 100 dugout canoes buried in the sediments of Newnans Lake near Gainesville, Florida. Radiocarbon assays revealed that 41 of 55 canoes studied were from the Late Archaic period, dating between 2300 and 5000 B. P. Analysis of canoe form and comparison to the small number of other known Florida Archaic period canoes correct previous ideas about early canoes. Patterns of wood choice and manufacturing techniques known from younger canoes were in place during the Late Archaic. The Archaic period canoes from Newnans Lake are indistinguishable from canoes produced in later periods and are not the crude, short, blunt-ended type thought to represent the earliest dugout canoes. Thwarts or low partitions on almost half of the Archaic canoes studied confirm a long temporal span to the canoe-making tradition of peninsular Florida. Middle and Late Archaic groups had boat-building and related technologies in place 7,000 years ago and were expanding into areas with newly emerging freshwater resources created by higher water tables.

Calibrated Radiocarbon Dating at Keatley Creek: The Chronology of Occupation at a Complex Hunter-Gatherer Village

Abstract: This paper provides an analysis of radiocarbon dates acquired during earlier and recent field seasons at the Keatley Creek site, southern British Columbia. Results indicate that early occupations predating 1900 cal. B.P. occurred, but were not likely associated with population aggregation and large housepits. The aggregated village appears to have emerged by approximately 1700 cal. B.P. and was abandoned at approximately 800 cal. B.P. A break in the occupational sequence is recognized at 1450-1350 cal. B.P and one other short break may have occurred shortly after 1250 cal. B.P. Peak socioeconomic complexity appears to have been achieved between 1350 and 800 cal B.P. Climatic warming may have provided a selective environment favoring population aggregation and intensification during this time. The final abandonment of the Keatley Creek village appears to have been part of a regional phenomenon suggesting the possibility that climatic factors were important in this case as well.

The local and the distant in the origin of Casas Grandes, Chihuahua, Mexico

Abstract: Casas Grandes (or Paquime), in northwestern Chihuahua, Mexico, is the largest and possibly the most complex community in the prehistoric Pueblo world. The literature is, and always has been, dominated by models that attribute the origin of this center to impulses coming from outside of the region. These arguments rest on the assumptions that the Casas Grandes area was underpopulated before the development of the center, and that there was little cultural continuity between Casas Grandes and its local predecessors. We use old and new data to argue against both of these ideas and in favor of in situ development of the center of Casas Grandes.

Exploring the Ubiquitous through the Unusual: Color Symbolism in Pueblo Black-on-White Pottery

Abstract: One of the common design characteristics on black-on-white pottery from the eleventh and twelfth centuries in the northern American Southwest is the use of thin, parallel lines (hachure) to fill the interior of bands, triangles, or other forms. This essay explores a proposal offered by Jerry Brody that hachure was a symbol for the color blue-green. Brody's proposal is examined by exploring colors and color patterns used to decorate nonceramic material from the Chaco Canyon region of northwestern New Mexico. His proposal is supported and the implications of this conclusion for Chaco Canyon and for future studies of this nature are discussed.

Postmarital Residence Practices in the Windover Population: Sex-Based Dental Variation as an Indicator of Patrilocality

Abstract: This study examines postmarital residence patterns at the Windover site, an Early Archaic occupation located in east-central Florida. Residence patterns are assessed using a population genetics model based on isolation by distance and migration matrix methods. Variation in nonmetric dental trails is examined among a group of 40 adult males and 43 adult females. The sex with the higher within-group variance is considered the more mobile sex, thereby providing a possible reflection of residential patterns. Results indicate that females are almost twice as variable as males, thus suggesting patrilocality. However, this result is not statistically significant at the .05 probability level. Additional lines of evidence are assessed in conjunction with dental data. Specifically, ethnographic data indicate that subsistence and sexual division of labor are important factors related to social organization, including residence. Although these lines of evidence can be used to support the dental data and patrilocality, they are not conclusive. Future studies of activity patterns, discase, mortuary remains and material culture may help to clarify the issue of postmarital residence patterns at Windover.

The Shaman-Priests of the Casas Grandes Region, Chihuahua, Mexico

Abstract: The Casas Grandes culture flourished between two well-known regions: Mesoamerica and the North American Southwest An analysis of Medio period (AD 1200-1450) pottery suggests that Paquime, the center of the Casas Grandes world, was dominated by shaman-priests The pottery includes images that document a “classic shamanic journey” between this world and the spirit world These images can be connected to the leaders of Paquime and to valuable objects from West Mexico, indicating that the Casas Grandes leadership had more in common with the Mesoamerican system of shaman-leaders than with the political system of the Pueblo world of the North American Southwest

Isotopic evidence for diet in the seventeenth-century colonial Chesapeake

Abstract: Excavations of colonial period sites in Maryland and Virginia have produced human remains dating to the seventeenth century. In this study, we analyze stable isotopes of carbon and nitrogen from these remains to explore aspects of the diets of the individuals represented. Analyses of both stable carbon and nitrogen isotopes were conducted on preserved protein while stable carbon isotope analysis was also conducted on preserved biological apatite. Carbon isotope values (δ 13 C‰) ranged from -10.5 to -20.5 for collagen and -5.1 to -12.5 for bioapatite. Nitrogen isotope values (δ 15 N‰) ranged from 9.9 to 14.4. The data suggest dietary diversity among the individuals examined. Three factors contribute to this diversity: the availability of maize, variation in immigration histories of the individuals, and the differing lengths of time they spent in the American colonies.

Abstract: Falls Prehistoric Site: Volume III. Appropriately, the first chapter of this collection (and one of the best—though written after having lost most of his eyesight) is by Clark—on variability among Lower Paleolithic assemblages in Africa, with a stress on the role of lithic raw materials. The excellence and line of thought of Clark's chapter are also found in the chapter by Nick Ashton on the well-known bifaces from the Wolvercote Channel near Oxford, as well as in the chapter by Clive Gamble and Gilbert Marshall on the role of nodule form in determining final handaxe shape. Handaxes and their variability are themes that run throughout many of the 27 short chapters of this book. Many are brief reports on specific finds, notes on old collections, or reflections on particular artifact types, all of which lends a somewhat \"antiquarian\" (and very British) flavor to the collection. The English and Anglo-African settings of 17 of the 27 chapters are complemented by a few other (exotic!) study venues, i.e., Kazakstan, Korea, southern Spain and Italy. Generalizing (and a bit more speculative) chapters that go beyond (technological or typological) artifact studies include ones by Marcel Otte, Nicolas Rolland, and Ofer Bar-Yosef, but of these only the second is long enough to provide a sustained argument (namely about the first hominid colonizations of Eurasia), although all are interesting and provocative.
