Deciduous tooth dimensions in fetal rhesus monkeys from mothers with induced diabetes.

Thirty-four measurements of the deciduous dentition in 21 fetal rhesus monkeys from diabetic mothers (FDM) and 36 nondiabetic fetuses were compared in order to assess the effects of induced maternal diabetes on the teeth of third-trimester fetuses. After exclusion of 14 variates due to significant age-related variation, univariate statistical analysis suggested a trend toward smaller teeth in the FDMs. Multivariate discriminant function analysis indicated not only a clear separation between the two groups, with molar breadths and some incisor length and breadths serving as the best discriminators, but also that the deciduous dental dimensions in FDMs are smaller than in nondiabetic fetuses.

On the expression of sex dimorphism.

A procedure is developed and presented for the calculation of sex dimorphism in quantitative variates. Instead of expressing sex dimorphism by the male X/female X ratio, it deletes the area of overlap of the two curves and provides the proportion of males and females in terms of the areas under each curve. Examination of anthropometric variates among Eskimos from northwestern Alaska and the Hadza from Tanzania indicates that extremity measurements might be of special value for assessing the magnitude of sex dimorphism.

Trends and developments in physical anthropology, 1978-1979.

Members of the American Association of Physical Anthropologists were asked to supply information about their current programs and their own graduate training in order to compile a training directory and to analyze certain aspects of the discipline. The data indicate that the majority consider their graduate training to have been deficient, mainly in statistics, genetics, chemistry, physiology, and mathematics. The areas though most important for future research in physical anthropology include fields such a genetics, anatomy, ecology, physiology, and paleontology, although a great many individuals are engaged in teaching and research in other areas. A brief analysis of relative growth in the field over the last few decades indicates a serious imbalance between the number of new Ph.D.'s and available employment opportunities.

Shifting patterns of sex dimorphism in three Japanese populations.

Levels of sex dimorphism among three related Japanese populations were calculated for 19 anthropometric variates. Two of the groups were born and raised contemporaneously in Japan; one remained there permanently (the sedentes) and the other migrated to Hawaii. The third group comprised the Hawaii-born offspring of the migrants. The results show a clear reduction in levels of sex dimorphism in the migrants as compared to both the sedentes and the Hawaii-born. Upon finding that the migrant females were generally larger than those of the other two groups, and after reviewing certain sociocultural phenomena related to the migration, it is hypothesized that the reduction in sex dimorphism was a transient change brought about by preferential choice of mates by the male migrants.
