Tiwanaku and Its Precursors: Recent Research and Emerging Perspectives

The Lake Titicaca Basin provides a fascinating case study for examining the prehistoric rise of complexity and archaic state development. The development of the Tiwanaku state and preceding polities involved conjunctions of regional environmental, socioeconomic, and ideological transformations. Significant social, economic, and ideological diversity characterized each major phase, indicating that the creation of inclusive domains of shared values, practices, and identities was critical to the formation of polities in the region. Tiwanaku and its precursors were, in great part, incorporative sociopolitical phenomena in which social diversity remained vital throughout their histories.     

Violence in the Atacama Desert during the Tiwanaku period: social tension?

Tiwanaku influence significantly affected the lifestyle of the prehistoric peoples of the Atacama Desert as it represented an important period of social and economic change. Such intense changes as social stratification and new religious and ideological influences have always been characterized as peaceful ones. Palaeopathological studies based on the violence‐induced traumatic lesions of 64 well‐preserved human skeletons from an excavated funerary site named Solcor‐3 have facilitated a comparison between Pre‐Tiwanaku and Tiwanaku periods. Results show an increase in violence between males represented by low‐intensity skull traumas, arrow wounds and a high mortality rate between 20 and 30 years of age during the Tiwanaku period. The interpretation of this data is contrary to the model of peaceful acceptance of the changes that followed the Tiwanaku influence into the Atacama. At least for Solcor‐3, economic and political factors should be re‐considered in order to explain the emergence of social tension during the Tiwanaku period. In the future, more detailed studies will probably help to clarify if conflicts had also extended to other sites in San Pedro de Atacama under Tiwanaku influence.

Top-down or bottom-up: rural settlement and raised field agriculture in the Lake Titicaca Basin, Bolivia

Differing interpretations regarding the organization of past intensive farming are often distinguished as “top-down” or “bottom-up” perspectives. The development of intensive farming and its social organization are attributed to either nascent states and centralized governments or the incremental work of local communities or kin-based groups. We address the social organization of raised field farming in one region of the Lake Titicaca Basin of the Andean altiplano, Bolivia. We evaluate past research in the Katari Valley, including our own, based on recent settlement survey, excavation, and a variety of analyses. Taking a long-term perspective covering 2500 years, we find that relations of production and rural organization changed greatly over time in relation to changing sociopolitical conditions. Local communities played dynamic roles in the development and organization of raised field farming, yet its intensification and ultimate recession were keyed to the consolidation and decline of the Tiwanaku state. We conclude that the top-down/bottom-up dichotomy is overdrawn. Local communities and their productive practices never operated in a political or economic vacuum but both shaped and were transfigured by regional processes of state formation, consolidation, and fragmentation.     

The emergence of agropastoralism: Accelerated ecocultural change on the Andean altiplano, ∼3540–3120 cal BP

In the fourth millennium BP, there were major environmental and cultural changes on the Andean altiplano of South America, but the chronology remains vague. A recent synthesis describes a slow, gradual transition from hunting and gathering to agropastoralism. This proposal is tested by refining the date of the onset of more humid and stable conditions, around 3550 cal BP, based on a Bayesian model of 26 dates from Lake Wiñaymarka and an updated calculation of the lacustrine offset. This is compared to Bayesian models of 191 dates from 20 archaeological sites, which incorporate a number of recently processed radiocarbon dates. A synthesis is presented of 15 full coverage surveys, a summed probability distribution, and a Bayesian model of the transition to ceramics, which together support a scenario of a very rapid demographic increase. Fourteen models from archaeological sites are cross-referenced in a composite model, which identifies a brief, altiplano-wide emergence of agropastoralism with starting and ending boundaries of 3540 and 3120 cal BP, respectively. This starting boundary correlates strongly with the onset of improving environmental conditions, indicating synchronous cultural and environmental change. The suite of accelerating cultural changes included a marked reduction in mobility, a demographic surge, increased subsistence diversity, the adoption of ceramics, farming and the integration of camelid herding into a remarkably resilient economic strategy still in use today. This is a highly relevant but yet to be used comparative case study for the variable tempos of ‘big histories’, and ecocultural interactions that generate rapid, emergent episodes of wide-spread and enduring cultural change.     

Tiwanaku trade patterns in southern Peru

This paper provides data and analysis from an intensive settlement survey in the southwestern Titicaca Basin. This research was designed to assess the nature of Tiwanaku (AD 600–1100) long-distance trade. The survey area was placed between the prehistoric urban capital of Tiwanaku and its primary colony in Moquegua, a valley located on the Pacific watershed approximately 325 km away. The survey was specifically placed in an area where GIS analysis indicated a least-cost transit route between Tiwanaku and Moquegua. Field adjustments to the survey area were made based upon informant data about the historic location of caravan routes. The results of the survey indicate that there is a light but virtually continuous string of Tiwanaku occupation along the trails and roads in the area sampled between Tiwanaku and Moquegua. However, in contrast to the later Inca (AD 1450–1532) period pattern, Tiwanaku did not maintain way stations or build any kind of formal road system. The data indicate that Tiwanaku had indeed relied upon camelid caravans utilizing the least-cost pathways, but it did so in a more decentralized and informal way than the later Inca state.     

Tawantinsuyu Integration of the Chillon Valley,Peru: A Case of Inca Geo-Political Mastery

Abstract

Archeological and ethno-historical data from the coastal, transitional, and lower sierra variants of the Chillon Valley, Central Coast of Peru, have led to a new understanding of the nature of Inca political and economic control of one subjugated region. The data reveal that the region was settled unevenly by the Cuzqueños; a more intensive state occupation of the lower sierra is indicated. It is suggested that control of the valley was managed by choice from a geographical-political locus in the highland zone because of certain cultural and environmental circumstances in each valley variant that posed advantages and disadvantages for state operations. Major sites yielding evidence of integration into the Inca state are discussed within the context of such a settlement pattern.     

How many bones make five? The art and science of guesstimation in archaeozoology

Six faunal statistics are described and assessed by means of simulation. Of these, the ‘probable number of individuals’ (PNI) methods, which include the Lincoln and Krantz indices, are shown to perform remarkably well. The assumptions of these PNI procedures are given and circumstances under which PNI methods can be employed are described. Palaeoeconomic methods occupy a middle ground between classical statistical theory and experimental archaeology, hence the use of the term ‘guesstimation’: this ground is explored and it is shown that these methods can have a considerable bearing on the interpretation of taphonomic and ‘spatial’ (intra-stratum) regularities. Promising avenues for future research are indicated.     

“Funerary bundles” in the PPNB at the archaeological site of Tell Halula (middle Euphrates valley,Syria): analysis of the taphonomic dynamics of seated bodies

This paper presents the results of the taphonomic analysis of the burials from Tell Halula (Middle Euphrates Valley, Syria). The numerous burials recovered from this Pre-Pottery Neolithic B (PPNB) settlement, in addition to the large volume of field documentation, have provided an opportunity to study burials in more depth than is usually allowed. This data set is important because of the unique mode of deposition, the exceptional preservation of the related assemblages (including fabrics, mats, and basketry) and the highly standardized nature of the funerary practices. Although the burials were found in various stages of preservation and articulation, we will show that they all represented the same type of funerary deposit, namely seated burials, often encased in bottle-shaped funerary bundles, and that the variability found during excavation can be attributed to post-depositional taphonomic effects. We provide a study of the different forms that result from these taphonomic influences and highlight the importance of doing this type of analysis. We hope that this paper will be a valuable contribution to the growing body of literature surrounding both seated burials and the taphonomy of burials.     

Neurocranial abnormalities of the Gongwangling Homo erectus from Lantian,China

The Homo erectus cranium found at Gongwangling, near Lantian, China, and dated to ≈1.2 ma BP has been analyzed with respect to its evolutionary position. However, the remains, and especially the internal and external surfaces of the neurocranium, present a series of marked abnormalities. These irregularities consist principally of a pronounced cresting and scalloping of the external surface of the frontal bone and anterior parietal bone and a similar alteration of the internal surface of a mid transverse section of parietal bone that connects with the fossilization break across the anterior parietal bone. There is no obvious exposure of diploë on the surfaces. Woo (Vertebrata PalAsiatica 10:1–16, 1966) briefly ascribed these abnormalities to postmortem erosion, and Caspari (Am. J. Phys. Anthropol. 102:565–568, 1997) has attributed the irregularities of the right supraorbital torus to antemortem trauma. It has been suggested that the pervasive neurocranial alterations might be pathological. Computerized tomography (CT) analysis of the frontal and parietal bones revealed complete radiopacity of the anterior half of the fossil; it is possible to distinguish large frontal sinuses but other details, including in the area of the purported traumatic lesion, are invisible. However, in the posterior frontal bone and preserved portions of the parietal bone the diploë and tables are discernible. Externally on the frontoparietal section and internally on the transverse parietal piece, there are clear erosional lacunae in the associated table, combined with a thin layer of matrix which obscures the eroded diploë externally. The superficial irregularities are therefore due to postmortem taphonomic alterations of the bone and not pathological processes. In addition, it is apparent that the two pieces were embedded in the matrix at different angles, resulting in their differential erosion.     

The prehistory of northern Chile: A synthesis

Northern Chile, part of the south central Andes, consists of two main ecological subareas: extreme northern Chile, including the western valleys, and the Atacama Desert and oases. Different ecological conditions obtain in each subarea: puna, altiplano, and precordillera in the highlands; valleys, the desert, and oases in the intermediate zone; and coastal environments along the Pacific shores. In prehistoric times, all these environments were very interconnected. There are three different cultural traditions in the local prehistory: the early hunting and gathering tradition (10,000–4000 B.P.), the Chinchorro Tradition (7500–2500 B.P.), and the Altiplano or Andean Tradition (3000–0 B.P.). This proposed sequence is described, with emphasis on the early Chinchorro adaptations, including the important patterns of mummification, and its possible relation to tropical forest groups of the Amazon basin; and the Pre-Tiwanaku and later Tiwanaku and Inca developments, in relation to the circum-Titicaca region. The data presented in the paper are further developed to explore ideas and hypotheses for future research.     

Temporal frequency distributions of alluvium in the American Southwest: taphonomic,paleohydraulic, and demographic implications

The use of radiocarbon frequency distributions to reconstruct prehistoric human and animal populations must account for taphonomic loss and other factors that affect the archaeological and paleontological records. Surovell et al. (JAS, 36, 1715–1724) have recently proposed a correction for “taphonomic bias” that is based on the radiocarbon frequency of a global sample of volcanic deposits. Analysis of 717 radiocarbon dates sampled from the alluvium of the San Pedro and Santa Cruz rivers and their tributaries in southeastern Arizona shows that discovery and scientific biases also play an important role in the creation of radiocarbon frequency distributions, and that the rate of “taphonomic bias” in prehistory is not predicted by the radiocarbon frequency of volcanic deposits. The latter principle is further argued using a sample of 123 Pliocene to Clovis-age proboscideans from the San Pedro Valley. We propose an alternative model that is based on the nature of the stratigraphic record, with discovery bias, scientific bias, taphonomic loss, and the shape of the calibration curve all operating to influence the temporal frequency distribution of radiocarbon-dated prehistoric phenomena.
