1975 marked the end of a 20-year period of human biology research on physical environment. The focus then shifted from climatic adaptation to problems of nutrition, disease, and stress. However, many questions about human environmental patterns, especially in reference to their evolution, were abandoned rather than resolved.

The demonstrable relationship between temperature and morphology in extant primates (including humans) forms the basis of the interpretation of the Pleistocene hominin Homo neanderthalensis as a cold-adapted species. There are contradictory signals, however, in the pattern of primate craniofacial changes associated with climatic conditions.

From both laboratory and field work, we have gained major insights into human response to physical and social challenges. While these results were considered by most professionals to belong within evolutionary biology, in fact the intellectual structure sprang almost entirely from physiological equilibrium models.

While Neandertal morphological patterns, such as foreshortened extremities and low relative surface-area, may have explained some of the variance in cold resistance, it is suggested the adaptive package was strongly dependent on a rich array of physiological defenses. A summary of the environmental cold conditions in which the Neandertals lived is presented, and a comparative ethnographic model from Tierra del Fuego is used.

The physical task itself, the natural setting, biological work capacity, and behavioral patterns presumably condition productivity. This paper presents a model by which work output of Chinese cycle haulers was investigated, and outlines investigative techniques including work physiology, health assessment, cold response, and ethnography of the workplace and home.

From a poor barrio of a rural lowland Philippine fishing community, a sample of 25 boys and 25 girls who had completed first grade at 8 years was measured. This population may be considered moderately undernourished by NCHS but not Philippine standards.
