While I was in Pasadena for the TCAs, I got a chance to have a very interesting talk with Harvard professor Henry Louis Gates, Jr. He was at the press tour to promote his new PBS series 'Faces of America,' which debuts on Wednesday, February 10.

In the four-part follow-up to his 'African-American Lives' series, Gates traces the lineages of a number of celebrity guests via the use of both old-fashioned digging -- documents, genealogical investigations -- and cutting-edge genome research. Some of the guests include Eva Longoria, Yo Yo Ma, Stephen Colbert, Malcolm Gladwell, Dr. Oz and Meryl Streep.

Professor Gates and I talked mostly about what he found surprising about his research, and what guests were most surprised by their lineages. Of course, I also asked him about the aftermath of the "beer summit" with President Obama and James Crowley, the Cambridge police officer who arrested him for breaking into his own house last summer. You'd be surprised what the officer gave Professor Gates as a keepsake of the incident.
