“…Ivanhoe and Chu (1996) used traditional osteometric methods and cranial and postcranial volumes to further address questions about nutrition and stress in various Indigenous groups from the San Francisco Bay area over time. These authors identified a link between body size and volume with changes in dietary patterns, specifically a reduction in body size related to an increased reliance on acorns for subsistence.…”

“…Given the number of palaeopathological studies that examine bone loss and osteoporosis (a frequent theme), it is perhaps not surprising that this early example of "shape" is also concerned with bone quantity and quality reflective of poor nutrition and generalized disease stress.

Analyses of human skeletal shape and geometry are used to investigate questions related to habitual activities and physical lifeways, as well as biological distance and relatedness. Recently, these methods have been applied to research concerning human evolutionary predisposition for disease, as well as functional experiences of pathological conditions. The use of these methods to address palaeopathological questions are relatively new, but related questions and approaches are gaining momentum. This manuscript provides an in‐depth review of the current state of this palaeopathological research by undertaking a meta‐analysis of anthropological literature. From the results of the meta‐analysis, we observe an increase in the use of quantitative shape analyses in palaeopathology, and identify four key themes in this literature: (1) description and diagnosis, (2) shapes that increase pathological risk, (3) shape change that arises from pathology, and (4) shape used for social insight. As this area of study develops, we recommend adaptations to measurement and data collection; comparative examinations of remains at the individual, population, and species levels; and, when possible, representation of all human variation through the inclusion of pathological individuals in geometric analyses. Palaeopathologists are ideally suited to investigate the relationship between bone shape and health, which may prove essential to the continued understanding of disease in both past and contemporary contexts.

“…Biological continuity of the Ryan Mound has been surmised as a result of cultural continuity (Ivanhoe & Chu, ; Jurmain, ; Leventhal, ; Weiss, ). Yet, as early as 1990, Jurmain () suggested that the biological relationship of the burials would need evaluating.…”

“…For example, cross‐sectional shapes of bones, which are used to determine activity patterns, can be affected by population differences, especially when these differences impact on body shape (see Weiss, ). Cranial measurements, which have been used to reconstruct the health of past peoples (Ivanhoe, ; Ivanhoe & Chu, ), can also be a sign of different populations (González‐José et al, ; Humphries, Maxwell, Ross & Ubelaker, ). Population (and specifically genetic) effects on osteoarthritis, dental health, stress fractures, and bone mineral density have been confirmed in clinical studies (see Weiss, ).…”

This study illustrates the importance of testing for biological continuity. Nonmetric studies provide a way to examine relationships within a sample to determine biological continuity. For the Ryan Mound, new populations may have moved into the region early on as part of the Meganos intrusion, or new populations may have moved into the region later, between AD 1500 and AD 1800. Comparative data from nearby sites further support the Meganos intrusion theory.

A quantitative bioenvironmental study of cranioskeletal size has been made of a latitude‐ordered sequence of 14 series of adult skeleton sets (N=305): the archaeological remains of aboriginal maritime peoples inhabiting the west coast of North America between southern California and the Arctic. Of eight osteometric parameters of cranioskeletal size developed, the most important are partial skeleton volume (PSK) and cranial capacity (CC); and the principal bone‐affecting environmental factors are the northerly climate (CLIM2c), the reconstructed diet deficient in calcium and overabundant in animal foods and vitamin D (DIET3c), and demographic stress (DSg). Prior research has demonstrated that cranioskeletal size increases with geographical latitude and decreases under dietary calcioprivation and unphysiologically high birth rates. Upon linear multifactorial statistical analysis our main finding, limited to the Amerindian subsequence (n=11 series) from the Santa Barbara Channel, the San Francisco Bay Region and the Northwest Coast, is that PSK and CC vary in direct proportion to CLIM2c, and inversely with DIET3c and DSg. Controlling for the latter two osteoantitrophic factors, coastal Amerindian female PSK rises by 9% between 34 and 54°N latitude, CC by 5%; and the male incremental rates are somewhat higher, 13 and 10%, respectively. This newly discovered climate‐dependent race cline, an example of Bergmann's Rule, is interpreted as factual evidence of a mid‐Wisconsin or earlier arrival date for the first Palaeoindians. Cranioskeletal size of the very small (n=3 series) Western Eskimo subsequence approximates the northernmost values of the coastal Amerindian distribution. © 1998 John Wiley & Sons, Ltd.
