Adriana Scott was adopted from Mexico when she was just weeks old. While growing up on Long Island, N.Y., she noticed that she looked nothing like her cousins. She had no idea why she excelled at certain things. "I'm very into music and into dancing," she says. "My family's not like that, really." And she always believed her quirks were hers alone: "Nothing like, 'Oh, I got this from my mom, or I got this from my dad.' It's kind of just been like me." But what she didn't know was that she had an identical twin sister who lived just miles away in New York City. Correspondent Lesley Stahl reported on their remarkable reunion.
