Craniometric Relationships of Plains Populations: Historical and Evolutionary Implications

Abstract

Large skeletal samples from cemeteries in the Northern Plains near Mobridge, South Dakota have made possible the accurate determination of craniometric relationships between populations ancestoral to the historic Arikara. There is considerable change throughout the approximately 200 years represented, due primarily to gene flow from adjacent Siouan speaking groups. Arikara crania from the Northern Plains are seen to be morphologically similar to earlier crania further south, in particular St. Helena materials in northeastern Nebraska. This offers Support for the archaeological hypothesis that Coalescent Tradition cultures grew out of the Central Plains Tradition. Early crania from the Northern Plains are markedly different from those in the Central Plains and more similar to historic Mandan. The craniometric evidence argues for biological continuity rather than replacement in the Plains area.     

Dental Discriminant Sexing of Arikara Skeletons

Abstract

Two discriminant functions based on buccolingual and mesiodistal dental measurements are presented. These formulae aid sex determination of Arikara Indian skeletons recovered from the Northern Plains. Formula verification techniques indicate sex identification accuracy of at least 80%. These formulae are useful when skeletal preservation is poor or as an aid in sexing subadults.     

Toward a Cultural Understanding of Human Microevolution on the Great Plains

Abstract

In order to explain the patterns of similarities and differences among the Plains skeletal populations analyzed by physical anthropologists, the populations must be viewed in the context of the sociocultural systems whichproduced them. Close cooperationbetween physical anthropologists, archaeologists, ethnohistorians, and linguistsis needed if this is to be accomplished. This paper attempts to set the stage for such studies by sketching out some of the aspects of the Plains Indian cultural environment which affected population genetics, material culture, and communications systems. On this basis, an attempt is made to interpret the results of some of the other papers in this volume.     

Some Wooden Scraper Handles From the Great Plains and The Southwest

Abstract

Adze-shaped scraper handles of antler are well known from the Plains area. Tools of the same pattern, of wood, are less well known and are virtually unmentioned in the literature and the tool in both antler and wood is unmentioned from the Pueblo area. Data on size and distribution of a large group of these objects in wood, from both the Plains and the Pueblo area are presented here, with some discussion of their possible origin.     

Hell Gap: Paleo-Indian Occupation on the High Plains

Abstract

A resume of archaeological investigations in the Hell Gap Valley of southeastern Wyoming is presented. This research produced a detailed sequence of Plains PaleoIndian occupation of this section of the High Plains. from about 9000 to 5500 B.C. Identifiable complexes recognized include Goshen, Midland, Folsom, Agate Basin, Hell Gap, Alberta, Cody, and Frederick. Materials recovered represent camping activities rather than the better known game kills, and add dimension to our knowledge of Plains Paleo-Indian cultures.     

Demography And Disease Patterns In A Protohistoric Plains Group: A Study ofthe Mobridge Site (39WW1)

Abstract

Epidemic disease has often been cited as the major factor causing historic depopulation of Native American groups. Because a range of infectious diseases introduced by Europeans struck different tribes at different times, the effects of these diseases or the outbreak of epidemics were not uniform for all groups. The Arikara of the American Plains wereamong the last North American Indian groups to experience direct contact with Europeans. However, indirect contact with introduced infectious diseases may have reduced these Plains protohistoric groups prior to established relations with Europeans. Historic depopulation of the Arikara and a demographic study of the skeletal remains from the Mobridge site (39WW1 l are the focus of this case study of the protohistoric population dynamics of a Native American group. Disease patterns are used in the demographic analysis to aid in the interpretation of observed mortality patterns. Evaluation of the skeletal remains from the Mobridge Site includes life table reconstruction and differential diagnosis of skeletal pathology complexes. Results of these analyses show that certain underlying disease processes evident skeletally correspond to deviations in the age distribution. Thus; the protohistoric mortality patterns of Mobridge appear to reflect the early stages of impact from introduced diseases.     

High Plains wheat mosaic virus: An enigmatic disease of wheat and corn causing the High Plains disease

Brief historyIn 1993, severe mosaic and necrosis symptoms were observed on corn (maize) and wheat from several Great Plains states of the USA. Based on the geographical location of infections, the disease was named High Plains disease and the causal agent was tentatively named High Plains virus. Subsequently, researchers renamed this virus as maize red stripe virus and wheat mosaic virus to represent the host and symptom phenotype of the virus. After sequencing the genome of the pathogen, the causal agent of High Plains disease was officially named as High Plains wheat mosaic virus. Hence, High Plains virus, maize red stripe virus, wheat mosaic virus, and High Plains wheat mosaic virus (HPWMoV) are synonyms for the causal agent of High Plains disease.TaxonomyHigh Plains wheat mosaic virus is one of the 21 definitive species in the genus Emaravirus in the family Fimoviridae.VirionThe genomic RNAs are encapsidated in thread‐like nucleocapsids in double‐membrane 80–200 nm spherical or ovoid virions.Genome characterizationThe HPWMoV genome consists of eight single‐stranded negative‐sense RNA segments encoding a single open reading frame (ORF) in each genomic RNA segment. RNA 1 is 6,981‐nucleotide (nt) long, coding for a 2,272 amino acid protein of RNA‐dependent RNA polymerase. RNA 2 is 2,211‐nt long and codes for a 667 amino acid glycoprotein precursor. RNA 3 has two variants of 1,439‐ and 1,441‐nt length that code for 286 and 289 amino acid nucleocapsid proteins, respectively. RNA 4 is 1,682‐nt long, coding for a 364 amino acid protein. RNA 5 and RNA 6 are 1,715‐ and 1,752‐nt long, respectively, and code for 478 and 492 amino acid proteins, respectively. RNA 7 and RNA 8 are 1,434‐ and 1,339‐nt long, code for 305 and 176 amino acid proteins, respectively.Biological propertiesHPWMoV can infect wheat, corn (maize), barley, rye brome, oat, rye, green foxtail, yellow foxtail, and foxtail barley. HPWMoV is transmitted by the wheat curl mite and through corn seed.Disease managementGenetic resistance against HPWMoV in wheat is not available, but most commercial corn hybrids are resistant while sweet corn varieties remain susceptible. Even though corn hybrids are resistant to virus, it still serves as a green bridge host that enables mites to carry the virus from corn to new crop wheat in the autumn. The main management strategy for High Plains disease in wheat relies on the management of green bridge hosts. Cultural practices such as avoiding early planting can be used to avoid mite buildup and virus infections.     

Archaic Skeletal Remains from the Central Plains: Demography and Burial Practices

Abstract

Recently a number of reports on Plains Archaic skeletal material have been published which quadruple the number of burials described and analyzed in the literature. Although the total number of burials is still relatively small, it is large enough to allow research to begin in paieodemographic aspects of the central part of thePlains and the suggestion of burial patterns for these materials. By combining all Archaic burials from the Plains a demographic profile has been developed. It is compared with other Archaic populations from the eastern United States, and with a Plains population dating after A.O. 1000. The results of the analysis show that with few exceptions burial patterns and the demographic picture of the Plains are quite stable over time, although differences are found in metric and non-metric variations in both the time and space continua. The analysis further shows that certain anomalous conditions in the skeleton appear to be much more prevalent inArchaic material than in recent material from the same area. The results finally suggest that Archaic people in the demographic and burial practice continua are quite similar to later populations, at least through Middle Mississippian populationsin the Plains.     

A Shoshonean Origin for the Plains Shield Bearing Warrior Motif

Abstract

The shield bearing warrior is a distinctive motif characteristic of the rock art of the Northwestern Plains. It also occurs commonly in the eastern Great Basin as an element of Fremont rock art. Detailed similarities between Plains and Great Basin shield figures suggest cultural relationships between the two areas. This has led some authors to propose that the motif originated in the Northwestern Plains and diffused to the Great Basin. Others argue that the motif spread from the Great Basin to the Plains. Relative dates recently obtained for shield figures at Northwestern Plains sites support the latter hypothesis. A Shoshonean origin for the Northwestern Plains shield figures is suggested by the dates, and the coincidence between the distribution of the motif, the distribution of diagnostic Shoshonean artifacts. and the ethnohistorically known range of the Plains Shoshone. It is suggested that the Shoshone borrowed the motif from the Fremont Culture during a period of interaction between the two groups.

The shield bearing warrior, a distinctive motif that depicts a pedestrian warrior whose body is represented by a large circular shield (Fig. 1), is frequently encountered in the rock art of the western United States. It is especially common at sites on the Northwestern Plains and in the eastern Great Basin (Fig. 2).

Temporal And Geographic Patterning of Relative Head Height in The Central Plains And Middle Missouri Areas

Abstract

Temporal and geographic patterning of vault height evaluated as the Auricular Mean Height Index is examined in samples of crania from the Central and Northern Plains. Crania are placed into two large categories: one consisting of historic Caddoan speakers and their ancestors, the other of Mandan speakers and their ancestors. Woodland crania from the Central Plains and Middle Missouri areas are added to their respective groups for part of the analysis. Time consistently shows a strong relationship to Auricular Mean Height Index; geographical latitude is equivocal but does exhibit a relationship to the vault height index in Central Plains-Caddoan without Woodland. Auricular height decreases with the passage of time and increases as one proceeds northward. The analysis further shows that Central Plains Caddoan groups have higher vaults than Middle Missouri-Mandan crania at a given point in time and space. That cranial morphology is different in the groups supports the notion that gene pool differences are responsible. The causes of decreasing head height through time are unknown.     

A Plains Woodland Burial from the Badlands of Western Nebraska

Abstract

Late Plains Woodland burial from a badlands region of western Sioux County, Nebraska produced the nearly complete skeleton of a robust adult male. Burial practices and associated grave goods are typical for the Woodland culture. However, osteological analysis has revealed a pattern of physical characteristics for the human skeleton which shows no real affinity to known Woodland populations to the south and east. Rather, the traits resemble very closely those of the nearly contemporaneous Late Middle Period people of Wyoming, to the immediate west. This lends evidence in support of recent hypotheses regarding the spread of Woodland culture across the central and western Plains.     

Was There a Northwestern Plains Sub-Culture? An Ethnographical Appraisal*

Abstract

On the basis of an examination of economy, political organization, intertribal warfare, religious life, and other factors, there is no justification for regarding the Northwestern Plains as a distinct division of the Plains Indian Culture Area.     

Neutron Activationianalysis of Obsidian:

Abstract

By a process of neutron activation, obsidian samples from an archaeological site may be traced to their quarry sources. The potential of this type of information remains largely unexplored and this paper is one small example of its application to Northwestern Plains Archaeology.     

Archeological Investigations at the Spawn Mound, 39LK201, Lake County,South Dakota

Abstract

The Spawn Mound, 39LK201, overlooking Brant Lake in eastern South Dakota, appears to be a Plains Woodland burial mound later used by historic Dakota for secondary interments. The 1966 excavations revealed two burial pits believed to be contemporaneous with the erection of the mound, which were assigned to the Plains Woodland component, and a third pit at the center of the mound which has been assigned to the historic Dakota. Each of the Woodland burial pits contained at least three individuals buried in the flexed position. The intrusive pit contained the remains of at least two individuals, apparently “bundle” burials. These intrusive burials were accompanied by European trade items.

On the basis of the limited ceramic material from the mound, including one rim sherd of the Ellis Cord Impressed type, as well as various lithic materials recovered in the mound fill, the Plains Woodland component has been tentatively assigned to the Loseke Focus. The historic burials would appear to date between A. D. 1800-1850.     

The Great Bend Aspect: A Multivariate Investigation Of Its Origins And Southern Plains Relationships

Abstract

The origins of the Great Bend aspect as well as its relations with a series of southern Plains sites are analyzed using ceramic attributes and multivariate statistics. Although the data is inadequate in certain areas the results suggest that in-situ development from earlier cultural groups is a more likely explanation than is a migration of peoples from the southern Plains.     

The Mississippian Heartland and Its Plains Relationship*

Abstract

The Cahokia site near East St. Louis, Illinois, was a gateway on the northwestern frontier of the Mississippian heartland. Its exact relationship to other Middle Mississippi cultures and to cultures of the Plains and Upper Great Lakes ar ea is still not fully under stood. It is clear, nonetheless, that these relationships, when more completely known, will prove to be :inuch more complicated than any suggested in current literature.     

Avonlea Point Occurrence in Northern Montana and Canada

Abstract

This report is a follow up of the 1961 Kehoe-McCorquodale presentation in the Plains Anthrdpqlogist of the Avonlea point as a horizon marker for the Late Prehistoric Periood in the Northwestern Plains, Montana Avonlea data are discussed, compared and combined with Canadian data to develop an expanded picture of regional Avonlea “culture”. A critique of the kehoe-McCorquodale generalizations reinforces essential hypothesis and further clarifies Avonlea spatial and temporal parameters.
