The Importance of Ancestry
When Oscar®-winning actors, Olympic Games medalists and celebrated musicians allowed Dr. Gates to trace their roots, many were surprised by the results.
Actress Eva Longoria always thought of herself as a Mexican-American, but a DNA test showed that she's actually 70 percent European, 27 percent Native American and 3 percent African.
"To know that I have a majority Spanish blood is a little...you know, I've been so proud of being Mexican—Mexican from Mexico," she says. "To know that that's not really who I am."
"It's not only who you are," Dr. Gates says.
Cutting-edge DNA research also leads to some surprising family connections. Eva finds out she's related to Grammy®-winning cellist Yo-Yo Ma, and actress Meryl Streep discovers she's linked to director Mike Nichols, a man she's worked with on four films.
