They then move to their own analysis of Gordon Creek Woman to demonstrate the value of their morphometric techniques in addressing questions of biological affinity. In this reply we clarify and amplify our position on the key issues on which they challenge us, and we evaluate their morphometric analysis of Gordon Creek Woman. To our previous call for bioarchaeologists to more explicitly acknowledge the political environment in which questions of biological affinity currently arise, we add our concern that the methodologies used have their own set of problems and limitations.

Stress, a concept addressing the consequences of disruptive events on individuals and populations... more Stress, a concept addressing the consequences of disruptive events on individuals and populations, can be a useful integrative idea. The stress process has much in common with its sister concept of adaptation. However, where adaptation focuses on “adaptive” or positive consequences, stress redresses an imbalance by focusing on the costs and limits of adaptation.In this paper we first review the interdisciplinary roots of the stress concept. While most stress research derives from research in environmental physiology, Selyean concepts of stress (involving increased catecholamine and corticosteroid output) have forced an expansion toward greater concern for perceptual and psychosocial stressors. What is largely missing from all traditions, however, is concern for sociopolitical processes which are not easily adapted to and consequently are persistent and pervasive causes of stress.Studies of stress in prehistoric, historical, and contemporary populations by biological anthropologists vary, in a complementary way, as to ability to delineate aspects of the stress process. Whereas the paleopathological methods of the prehistorian provide a suite of skeletal indicators of stress response, and the demographic measures of the historian provide a detailed analysis of consequence, a wide variety of techniques for examining all levels of the stress process are potentially available to those studying contemporary populations. In order to better utilize information from different levels of analysis one needs to focus on measures of stress, such as infant mortality, which are accessible at all levels. Biological anthropologists are in a unique position to elucidate the human condition if, via concepts such as stress, attention is paid to both human adaptive and political economic processes.

Using procedures described by Morton (1973), Harpending and Jenkins (1974), Jorde (1980), and others the exchanges between subdivisions which make up the matrices are made column stochastic and analyzed to predict genetic kinship. Subsequently the kinship estimates within and between subdivisions can be interpreted as genetic covariance and compared to the actual geographic distances between the respective subdivisions using a principal components analysis. In the present paper we extend these results by applying nonmetric multidimensional scaling to the migration matrices, and to isonymy matrices based on the same communities. We demonstrate that the multidimensional scaling configurations of marital migration represent the actual geographic relationships between the communities quite effectively for this particular case study from historical Massachusetts. Moreover, we argue that while these migration data may provide good estimates of social and genetic exchange between the subdivisions, surname analysis may also be informative of processes not revealed in the migration matrices alone.

Genetic inferences are drawn, and the requisite assumptions considered. The effect of geographic distance on genetic kinship is predicted using Malécot's isolation-by-distance model. The resulting estimates are discussed in terms of geographic and historical factors. The configuration of communities as predicted by kinship values approximates closely their actual geographic locations. Estimated genetic heterogeneity was low for the historical Connecticut Valley population, and community isolation breaks down rapidly over time. The region thus assumes its place among a number of sedentary, agricultural populations for which the isolation-by-distance model provides an adequate representation. A regression analysis which includes variables in addition to distance indicates that historical and economic factors contribute some additional explanatory power to the distribution of mating frequencies.
