Research Working with Laurence D. Mueller, Graves found that
population density is an important factor in determining both the immediate chances of survival and the course of
natural selection for small organisms such as fruit flies. In "Chance, Development, and Aging",
Human Biology December 2001, Graves wrote that the explanation of individual patterns of
aging must take into account subtle mechanisms such as extensive chance variations in cell number and connections, in cell fates during differentiation, and in physiological patterns that arise during development. Graves has studied the tiny insects for more than a decade in pursuit of greater understanding of
senescence, the process of aging. In addition to the study of aging, Graves is interested in the
history and
philosophy of science as it relates to the biology of race and racism in western society. He has received a fair amount of attention from the press for his writings on this topic, especially his strong statements about the socially constructed nature of race.
