DNA of Deadbeat Voles May Hint at Why Some Fathers Turn Out to Be Rats By NICHOLAS WADE (NYT) 900 words Published: June 10, 2005 Some male prairie voles are devoted fathers and faithful partners, while others are less satisfactory on both counts. The spectrum of behavior is shaped by a genetic mechanism that allows for quick evolutionary changes, two researchers from Emory University report in today's issue of Science. The mechanism depends on a highly variable section of DNA involved in controlling a gene. The Emory researchers who found it, Elizabeth A.D. Hammock and Larry J. Young, say they have detected the same mechanism embedded in the sequence of human DNA but do not yet know how it may influence people's behavior. Voles, not to be confused with the burrowing, hill-making mole, are mouselike rodents with darker coats and fatter tails. The control section of their DNA expands and contracts in the course of evolution so that members of a wild population of voles, the Emory researchers have found, will carry sections of many different lengths. Male voles with a long version of the control section are monogamous and devoted to their pups, whereas those with shorter versions are less so. People have the same variability in their DNA, with a control section that comes in at
