People all over the world see themselves as members of subgroups- sometimes as small as a tribe or family, other times as large as a continental “race”. The U.S. Census Bureau counts individuals as members of one of four races (or “other”). Yet many geneticists argue that humans cannot be divided into such categories based on their DNA. On the other hand, some techniques have been devised recently to use DNA testing to discern the geographic origin of people’s ancestors. On Wednesday, November 18, 2009 in Kent Library’s Sadie’s Place Dr. Gathman will discuss recent research on human genetic variation and whether the idea of “race” has any scientific meaning. The presentation is open to all, and refreshments will be served. For more information, please go to: http://library.semo.edu/info/athenaeum.shtml .
