Coastal, valley, and oasis interaction
The existing biocultural links are analyzed among ancient inhabitants of the Cochabamba valleys (Bolivia) from the Formative and Tiwanaku periods, coastal and inland Azapa region (Chile) from the Late Archaic to the Late periods, and the Atacama Desert oases (Chile) from the Formative period to the time of European contact. Craniometric information obtained from a sample of 565 individuals from different sites of the studied regions was evaluated…
Valley to Valley
One of the most interesting problems facing the interpretation of south central Andean prehistory is to decipher the genetic relationships among ancient groups that inhabited this region. This study evaluates the biological relationships between the ancient inhabitants of the coast and interior valleys of the Azapa region in northern Chile and the Cochabamba valleys of Bolivia, with reference to highland Tiwanaku groups. Craniometric data (N = 29…
Sexual Dimorphism in Prehispanic Populations of the Cochabamba Valleys, Bolivia
The expression of sexual dimorphism may vary across time and space, as well as within and between populations depending on genetic and environmental factors that influence growth and development. The objective of the present work is to contribute to the knowledge of factors that determine the physical characteristics of ancient human groups in the eastern valleys of Cochabamba—a key region for cultural development, inter-regional interaction with…
Boards and Cords
For over a century, a number of ambiguous typologies have been employed to distinctly categorise types of artificial cranial deformation. This paper provides a quantitative method, based on multiple dimensions and discriminant function analysis, by which to assign skulls not only into discrete categories: deformed or not, but also by type: annular or tabular. A series of prehispanic, adult, human crania (n = 469) from archaeological sites in Arge…
Effects of artificial deformation on cranial morphogenesis in the south central Andes
One of the most interesting issues of the interface between biology and culture is the artificial deformation of the skull. This modification is produced during early morphogenesis through the use of devices that alter the normal growth and development, to obtain a culturally established model. This paper, using a large cranial sample from the South Central Andes (1586 individuals), describes and documents a detailed morphometric study of the cha…
The genetic divergence of prehistoric populations of the south‐central Andes as established by means of craniometric traits
The peopling of the south‐central Andean region can be determined by exploring a combination of cultural, economic, and biological factors that influence the structure of populations and determine particular dispersals of gene frequencies. Quantitative characters from 1,586 adult crania of both sexes from northern Chile, northwestern Argentina, and the Cochabamba valleys in Bolivia were analyzed employing multivariate statistical analyses. Biolog…
