You can find virtually everybody black back as far as the 1870 census. Why 1870? That's when the ex-slaves first have surnames. But if you find your great-great-grandfather in 1870 and it says he's 50, that means he was born in 1820 and you're back to 1820 already. For an American that's pretty damned good, you know?

In 1957, when I was in second grade, black children integrated Central High School in Little Rock, Arkansas. We watched it on TV. All of us watched it. I don't mean Mama and Daddy and Rocky. I mean all the colored people in America watched it, together, with one set of eyes.

I'd say imagine that you wake up one morning when you're going through a midlife crisis. You're getting divorced. Your kids won't speak to you. Their faces are covered with acne, and you have to decide why you should get out of bed. That's the career you should pick. The one that keeps you going no matter what, even if your life is falling apart. That's how I feel about my career.

Ever since I watched 'Roots,' I've dreamed of tracing my African ancestry and helping other people do the same.

My father and I made genetics history. We were the first African-Americans and the first father and son anywhere to have their genomes sequenced.

I first learned that there were black people living in some place called other than the United States in the western hemisphere when I was a very little boy, and my father told me that when he was a boy about my age, he wanted to be an Episcopal priest, because he so admired his priest, a black man from someplace called Haiti.

Cuba is like going to a whole other planet. It's so different but it's so similar to the United States, to Miami. It's like a doppelgaenger. It's the mirror image. And I have no doubt, that once Cuba becomes democratic, that it will be the favorite tourist destination for Americans.
