Learn about the relatively recent invention of “race” and judge how well the concept applies to people today in this video from Finding Your Roots. Geneticist David Altshuler describes how people in the 19th Century developed a concept of race that had more to do with the social interactions and hierarchies of that time period than with biological differences. But even while the concept of race was forming, human relationships showed that race was less rigid than it was believed to be. In the video, Massachusetts Governor Deval Patrick learns about the relationship between two of his ancestors, a relationship that demonstrates that people made connections that defied stereotypes. Genetic analysis reveals that people are far more similar than they are different.
