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.

For centuries, taxonomists have been organizing the diversity of life. Aristotle was the first to attempt to do this. Then, in the 1700s, Carolus Linnaeus introduced the idea of genus and species. Later, Charles Darwin revolutionized science with the idea that species can change over time and that all animals may have a common ancestor.
