Radio Lab: Race
At the turn of the millennium, researchers succeeded in sequencing the entire human genome and found that humans, regardless of race, are more than 99.9% the same. But as scientists continue to look, is turns out that race might have a genetic signature. We visit a DNA lab to see if their machines can paint the portrait of a criminal. We stop by the lunchroom of a diverse middle school to ask students how they define their own race. Finally, we follow an Iraqi man back through his memories of the narrow divisions between Sunni and Shi'a that terrorized daily life in Baghdad.
