At the recent Who Do You Think You Are Live/National History Show in London, I had the chance to interview several interesting people. David Nicholson certainly qualifies as "interesting." He is the Director of DNA Worldwide and is a DNA expert. In this interview from RootsTelevision.com, David gives a brief background of the research you can accomplish by using DNA. Would you believe 170,000 years? David also described the services of DNA Worldwide.

Hint: If you are on a dial-up Internet connection, you may encounter "jerkiness" as the video downloads and tries to play. If so, simply click on PAUSE. You will then see the video continue to download in the background, and it will be stored temporarily on your hard drive. Then click PLAY once again, and it should be much smoother as the video is retrieved from your hard drive at full speed.
