The University of New Mexico Department of Anthropology presents, "Aging and Post-reproductive Life in a Traditional World: Behavior, Physiology and Theory" with UNM anthropology professor Hillard Kaplan on Thursday, Jan. 24 at 7:30 p.m. at the Maxwell Museum/Hibben Center. The event is free and open to the public. 

From field research conducted in lowland Bolivia with Tsimane Native South Americans, Kaplan shares vital information about the aging process among Tsimane forager-horticulturalists and the implications of understanding human evolution.

Kaplan, who directs the Tsimane Health and Life History Project, will review the latest findings on behavior, inter-generational transfers, physical function, immunocompetence and cardiovascular disease. Tsimane men and women continue to provide food for their children and grandchildren until about age 70, the modal age at death for traditional populations. Men and women adjust their time use as they age, adapting to physical decline. Cardiovascular disease is rare, and heart function remains preserved into the eighth decade of life. Immunosenescence, along with functional decline, appears to be the major driver in the increasing risk of mortality with age.

The lecture will conclude with a discussion on the theory of human lifespan evolution, and important new directions for research.

Kaplan received his Ph.D. from the University of Utah. His recent research and publications examine the evolution of human life course, focusing on integration of history theory in biology and human capital theory in economics, with specific emphases on fertility, parental investment and aging in developed, developing and traditional settings.  He has also conducted fieldwork with native South Africans.
