The role of canids in ritual and domestic contexts: new ancient DNA insights from complex hunter–gatherer sites in prehistoric Central California

This study explores the interrelationship between the genus Canis and hunter–gatherers through a case study of prehistoric Native Americans in the San Francisco Bay-Sacramento Delta area. A distinctive aspect of the region's prehistoric record is the interment of canids, variously classified as coyotes, dogs, and wolves. Since these species are difficult to distinguish based solely on morphology, ancient DNA analysis was employed to distinguish species. The DNA study results, the first on canids from archaeological sites in California, are entirely represented by domesticated dogs (including both interments and disarticulated samples from midden deposits). These results, buttressed by stable isotope analyses, provide new insight into the complex interrelationship between humans and canids in both ritual and prosaic contexts, and reveal a more prominent role for dogs than previously envisioned.     

Correcting temporal frequency distributions for taphonomic bias

In this paper, we expand upon a prior study [Surovell, T.A., Brantingham, P.J., 2007. A note on the use of temporal frequency distributions in studies of prehistoric demography. Journal of Archaeological Science 34, 1868–1877.] that explored the problem of taphonomic bias. Taphonomic bias refers to the tendency for younger things to be over-represented relative to older things in the archaeological record due to the operation of destructive processes like erosion and weathering. Using a database of radiocarbon dated volcanic deposits from Bryson, R.U., Bryson, R.A., Ruter, A. [2006. A calibrated radiocarbon database of late Quaternary volcanic eruptions. Earth Discussions 1, 123–124.], we develop an empirical model of taphonomic bias. In contrast to our prior study in which we modeled taphonomic bias as an exponential function wherein the likelihood of site loss remains constant through time, we argue that the probability of site destruction actually decreases with site age. We further demonstrate how this model can be used to correct temporal frequency distributions and extract demographic histories. We illustrate this approach using databases of radiocarbon dates from rockshelter and open-air sites in the Bighorn Basin, Wyoming, USA, and mammoths and humans in Siberia, Russia.

From early humans to farmers and herders—Recent progress on key transitions in Southwest Asia

Archaeologists conducting research on the Pleistocene and early Holocene prehistory of Southwest Asia have made a formidable series of new discoveries and fresh insights since 1987. This article examines recent progress and shortcomings on a series of diachronic research topics, including the transition to modern humans, the development of late Pleistocene regionalism and territoriality, the advent of sedentism near the end of the Pleistocene, the origins of food production, and the initial ascendance of social complexity.     

The Natufian: Settlement variability and economic adaptations in the Levant at the end of the Pleistocene

The relationship between current interpretations of Natufian settlement and subsistence and available archaeological data are examined in light of recent research, particularly in Jordan. Regional variability in adaptive strategies is discernible, particularly between forest and coastal sites versus steppe and desert sites. Greater evidence of plant processing and more intensive occupation characterize settlement in the former, although year-round occupation has yet to be conclusively demonstrated. Patterned variability also exists between two classes of steppe and desert area settlements. One set of steppe and desert sites is characterized by a broad range of activities and moderate settlement permanence and activity intensity, while less permanent occupation and more specialized activities focused primarily on hunting typify the other set of sites. Evidence for food production in the Natufian is examined and, although the domestication process may have begun, no morphological evidence exists for the domestication of plants or herd animals. Finally, worthwhile areas for future research are outlined.     

Stable isotope reconstructions of shellfish harvesting seasonality in an estuarine environment: implications for Late Holocene San Francisco Bay settlement patterns

Seasonality estimates based on stable isotope analyses of shellfish remains has been an important thrust of settlement pattern reconstruction, allowing researchers to place people on the landscape at points in space at different times of the year. In exposed coastal settings seasonality reconstructions are typically dependent on annual changes in water temperature. This paper has two goals. First, we continue development of a method for determining shellfish harvest seasonality in estuarine environments where annual salinity changes, not temperature, drive isotopic variation. Second, we contribute to settlement pattern studies by showing how small and large sites can be linked into a single system by examining different site types and shellfish species. Our case study focuses on the Late Prehistoric period of the San Francisco Peninsula, includes a large shellmound (CA-SMA-6) and an ephemeral camp (CA-SFR-171), and examines clam (Macoma spp.) and mussel (Mytilus spp.) harvesting. In this case, data support a fission-fusion settlement pattern, with periods of dispersal during late winter through early summer and aggregation in late summer through early winter.
