Bio

SHORT PROFESSIONAL BIOGRAPHY

I am an anthropologist who began my career by doing an ethnography of the Yomut Turkmen of northern Iran in the 1960s and 1970s. This ethnography focused mainly on social organization. The Yomut community I lived with, much of the time from December 1965 to October 1967, was a pastoral group and, in addition to my ethnography, I did research leading to articles about their pastoral economy and its relationship to other aspects of their lives. Beyond describing the social life of the pastoral Yomut, I developed the hypothesis that, for the Yomut and probably many other pastoral groups in the Middle East, nomadism was a political and military strategy as well as an economic one. After my initial work on the pastoral Yomut, I then moved on to do a demographic study of the Yomut in 1973-74 which was designed to test the hypothesis that the Yomut regulate their population density by social means in the manner theorized by Wynne-Edwards and Carr-Saunders. The research disconfirmed this hypothesis. Form there I went on test other evolutionary hypotheses with my Yomut data most of which were confirmed. I also developed some ideas about how human behavior is shaped by our evolutionary past. These include the cultural-and-reproductive-success hypothesis, the concept of adaptively relevant environments, and the theory that religion functions as a commitment device and that the psychological underpinnings of religion are evolved adaptations which help people to from and maintain cohesive groups. (My idea about religion is and expansion of Thomas Schelling’s idea about commitment and hard-to-fake signals of commitment.) These ideas are described on the page labeled “ideas” and in articles included on the “articles” page.

CURRENT RESEARCH INTERESTS

Developing theory concerning the evolutionary foundations of religion and morality; empirical evaluation of evolutionary hypotheses derived from evolutionary theory especially with data gathered among the Turkmen of northern Iran; refinement of theory in human behavioral ecology

FIELD RESEARCH AND OTHER DATA COLLECTION

Iran, 1965-1967: ethnography, social organization, and descriptive ecology of the Yomut Turkmen (16 months); library research on history of the Turkmen using various published and unpublished sources in Tehran (6 months) while waiting for research permission; ethnographic survey of Bakhtiari and Luristan (2 months)

Afghanistan, 1967: ethnographic survey of Nuristan and Hazarajat (2 months)

Iran, 1970: ecology of the Yomut Turkmen (2 months); (1 month additional in Tehran waiting for research permission)

Iran, 1973-1974 (12 months): survey to obtain social and demographic data for testing hypotheses concerning the behavioral ecology of the Yomut Turkmen; (3 months additional in Tehran waiting for research permission, consulting with Iranian scientists and arranging to ship material home after the field research was complete)

Venezuela, 1991 (1 month): pilot demographic study of the Ye’kwana.

Bay Islands of Honduras, 1993 (2 weeks): pilot project to determine the feasibility of future research on the island of Utila.

Bay Islands of Honduras, 1996 (2 months): research (with Lee Cronk and Shannon Steadman of Texas A&M University) on the cultural norms governing family relationships (the study focused on specific hypotheses about audience effects and Rashamon effects derived from evolutionary theory).
