Female genital cutting and mother's age at birth are associated with the sex of offspring in Africa
Female genital cutting (FGC) is widespread in Africa. Its short and long term medical consequences are widely reported. Here we report that FGC is associated with and may contribute to increases in the sex ratio at birth (Odds Ratio = 1.019; 95% C.I. = 1.007, 1.032) while mother's age at birth is inversely associated with probability of male birth (Odds Ratio = 0.998; 95% C.I. = 0.997, 0.999) in a generalized linear, logistic model with the proba…
A reconsideration of the origins of the type 2 diabetes epidemic among native Americans and the implications for intervention policy
Type 2 diabetes has reached epidemic proportions in many Native American communities in North America. The overwhelming majority of physicians, biomedical researchers, and medical ecologists continue to explain the astoundingly high prevalence rates of diabetes among Native Americans and other high prevalence populations in terms of yet-to-be-identified genetic factors. Recent experimental and epidemiological research, however, has brought to lig…

The Relationship of Inheritance Systems To Genealogical Structures and Male Longevity
It has been observed that in some populations male succession to petty offices and inheritance of impartible male property pass down a line of brothers before members of a more junior generation inherit or succeed. When the proper ty or office is conveyed to a member of a junior generation, populations vary as to whether the heir or successor is usually a son, a brother's son, or a sister's son. The present paper argues that these diverse pattern…
A Demographic Basis for Patrilineal Hordes
The evidence for patrilocal group organization among precontact hunter-gatherers is ambiguous. Observations among modern hunter-gatherers suggest that few, if any, are organized into patrilineal hordes or bands, but these observations stem from declining populations in transformed environments. These inadequacies in the data imbue the theoretical arguments concerning hunter-gatherer local organization with special importance. It is shown that eco…

On the Estimation of the Sizes of Local Groups in a Hunting-Gathering Environment1
The ancestors of the Hualapai and Havasupai Indians were once hunters and gatherers, some of whom did a little farming during the summer. The basic adaptation was to a hunting and gathering life and this adaption included local groups of the classic type with a mean size of twenty-eight. This paper presents a theory which retrodicts and accounts for the range of local group sizes and their probabilities (frequencies
