Scientist Discovers Gene Linked With Violent Behavior

Punk rock legend Henry Rollins, prone to his own violent behavior, hosts a television show that investigates the origins of the short fuse. In "Explorer: Born To Rage," Rollins and a diverse group of men agree to be tested for what is called "the Warrior Gene."

Scientists believe if the gene is non-functioning in men, they may be more prone to violent behavior.  "Born To Rage" airs at 9pm ET Tuesday on the National Geographic Channel.
