A1 Brown, Tony., Richards, Samuel, Mulvey, Laurie, Tony Brown Productions., WNET (Television station : New York, N.Y.), PB Insight Media PP New York YR 2005 AB About 100,000 years ago, defining race was not an issue because scientists agree that the first humans originated in Africa. Over the next 50,000 years, waves of humans left Africa and spread throughout the world. Today's human rainbow species is the result of that migration. This historic reality of genetic science came face to face with the modern concept of social race when students at Penn State University, who considered themselves as 100% Black or White, took a complex screening test that compared their samples with those of four regional anthropological groups. Tony Brown interviews Drs. Mulvey and Richards who co-direct the Race Relations Project at Penn State University.
