Datura quids at Pinwheel Cave, California, provide unambiguous confirmation of the ingestion of hallucinogens at a rock art site
David Robinson et al.
Proceedings of the National Academy of Sciences, forthcoming
Abstract:
While debates have raged over the relationship between trance and rock art, unambiguous evidence of the consumption of hallucinogens has not been reported from any rock art site in the world. A painting possibly representing the flowers of Datura on the ceiling of a Californian rock art site called Pinwheel Cave was discovered alongside fibrous quids in the same ceiling. Even though Native Californians are historically documented to have used Datura to enter trance states, little evidence exists to associate it with rock art. A multianalytical approach to the rock art, the quids, and the archaeological context of this site was undertaken. Liquid chromatography−mass spectrometry (LC-MS) results found hallucinogenic alkaloids scopolamine and atropine in the quids, while scanning electron microscope analysis confirms most to be Datura wrightii. Three-dimensional (3D) analyses of the quids indicate the quids were likely masticated and thus consumed in the cave under the paintings. Archaeological evidence and chronological dating shows the site was well utilized as a temporary residence for a range of activities from Late Prehistory through Colonial Periods. This indicates that Datura was ingested in the cave and that the rock painting represents the plant itself, serving to codify communal rituals involving this powerful entheogen. These results confirm the use of hallucinogens at a rock art site while calling into question previous assumptions concerning trance and rock art imagery.
Demographic Crises of Different Climate Phases in Preindustrial Northern Hemisphere
Qing Pei et al.
Human Ecology, October 2020, Pages 519–527
Abstract:
This research empirically analyzes the association between climate change, population size, and demographic crises as indicated by what we term “population checks,” or major wars, epidemics, and famines from AD 1000 to AD 1900 in the Northern Hemisphere based on historical records and climate reconstructions. We conducted this study at two temporal scales: (1) the entire study period of 900 years and (2) three climate phases according to temperature (cold, mild, and warm) of 300 years each. By adopting linear and nonlinear statistical methods, we found climate change and population size to have significant roles in driving the demographic crisis at the temporal scale of the entire study period. In terms of the three climate phases of 300 years each, we find that war is more closely correlated to climate change than to population size for all three phases. However, population size itself is more likely to trigger epidemics during mild and warm phases and is more important in relation to famines than climate change during all three climate phases. This study emphasizes the importance of scale in reviewing the social past in terms of climate change and population size. Empirical evidence of large-scale demographic crises within the three climate phases could also provide a timely reference for scientists or policymakers in addressing the potential effects of global warming.
Home Is the Sailor: Investigating the Origins of the Inhabitants of La Isabela, the First European Settlement in the New World
Douglas Price et al.
Current Anthropology, October 2020, Pages 583–602
Abstract:
This study focuses on the origins and diet of the seafarers on Columbus’s second voyage, individuals whose mortal remains were buried in the churchyard of the settlement of La Isabela. This was the very first European town in the Americas, founded by Columbus in the present-day Dominican Republic in early January 1494. Historical sources indicate that most of the crew came from the region of Andalucía, while the remainder came from a range of other geographical locations. It is also likely that some individuals had been born elsewhere and migrated to Spain before embarking on their transatlantic voyage. However, their precise origins remain unknown. In this study, we use both osteological analysis and isotopes — both light (C, N, and O) and heavy isotopes of strontium in the tooth enamel and bone of 27 individuals from La Isabela — to investigate questions of human provenience and diet. The results of our analyses indicate that while most of the individuals analyzed from the burial series at La Isabela were males from Spain itself, there were several unexpected females and infants, referred to vaguely by the historical sources, in addition to one local native and a person probably from Africa, implying that Africans took part actively in the Spanish venture of settling the New World from the very beginning.
Palaeolithic voyage for invisible islands beyond the horizon
Yousuke Kaifu et al.
Scientific Reports, December 2020
Abstract:
How Palaeolithic maritime transportation originated and developed is one of the key questions to understand the world-wide dispersal of modern humans that began 70,000–50,000 years ago. However, although the earliest evidence of maritime migration to Sahul (Australia and New Guinea) has been intensively studied, succeeding development of Paleolithic maritime activity is poorly understood. Here, we show evidence of deliberate crossing of challenging ocean that occurred 35,000–30,000 years ago in another region of the western Pacific, the Ryukyu Islands of southwestern Japan. Our analysis of satellite-tracked buoys drifting in the actual ocean demonstrated that accidental drift does not explain maritime migration to this 1200 km-long chain of islands, where the local ocean flows have kept the same since the late Pleistocene. Migration to the Ryukyus is difficult because it requires navigation across one of the world’s strongest current, the Kuroshio, toward an island that lay invisible beyond the horizon. This suggests that the Palaeolithic island colonization occurred in a wide area of the western Pacific was a result of human’s active and continued exploration, backed up by technological advancement.
Kinship and social organization in Copper Age Europe. A cross-disciplinary analysis of archaeology, DNA, isotopes, and anthropology from two Bell Beaker cemeteries
Karl-Göran Sjögren et al.
PLoS ONE, November 2020
Abstract:
We present a high-resolution cross-disciplinary analysis of kinship structure and social institutions in two Late Copper Age Bell Beaker culture cemeteries of South Germany containing 24 and 18 burials, of which 34 provided genetic information. By combining archaeological, anthropological, genetic and isotopic evidence we are able to document the internal kinship and residency structure of the cemeteries and the socially organizing principles of these local communities. The buried individuals represent four to six generations of two family groups, one nuclear family at the Alburg cemetery, and one seemingly more extended at Irlbach. While likely monogamous, they practiced exogamy, as six out of eight non-locals are women. Maternal genetic diversity is high with 23 different mitochondrial haplotypes from 34 individuals, whereas all males belong to one single Y-chromosome haplogroup without any detectable contribution from Y-chromosomes typical of the farmers who had been the sole inhabitants of the region hundreds of years before. This provides evidence for the society being patrilocal, perhaps as a way of protecting property among the male line, while in-marriage from many different places secured social and political networks and prevented inbreeding. We also find evidence that the communities practiced selection for which of their children (aged 0–14 years) received a proper burial, as buried juveniles were in all but one case boys, suggesting the priority of young males in the cemeteries. This is plausibly linked to the exchange of foster children as part of an expansionist kinship system which is well attested from later Indo-European-speaking cultural groups.
The origin and use of shell bead money in California
Lynn Gamble
Journal of Anthropological Archaeology, forthcoming
Abstract:
The Chumash Indians produced shell beads for thousands of years in the Santa Barbara Channel region, with special bead-manufacturing sites well-documented. Archaeologists specializing in this region have suggested that shell bead money was initially used about 800 years ago. Archaeological correlates are presented to help determine criteria for the identification of shell bead money versus shell beads used for other purposes, such as ornamentation and status markers. Based on multiple lines of evidence, I propose that the use of shell money started about 1,000 years earlier than previously thought in Southern and Central California, dating back to about 2,000 BP. Ethnohistoric and ethnographic sources document that currency was used to facilitate trade, extend social networks, purchase foodstuffs and objects, including ceremonial regalia, pay for services, and pay debts as part of redistribution. In Northern California, shell beads were used differently and were integral to bridewealth and debt that was incurred as part of this practice.
