Get ready for a segregated "Survivor." Race will matter on the upcoming season of the CBS show as contestants will be divided into four tribes by ethnicity. That means blacks, whites, Latinos and Asians in separate groups.The announcement was made on CBS' Early Show. Host Jeff Probst says the idea "actually came from the criticism that 'Survivor' was not ethnically diverse enough." He says the twist fits in perfectly with what "Survivor" does, saying the show is "a social experiment. And this is adding another layer to that experiment." Probst says contestants had mixed reactions to the racial divisions.
