Yo-Yo Ma speaks of the fruit that comes from diversity

Though Yo-Yo Ma is known for his music, he delivered the Nancy Hanks Lecture on Arts and Public Policy on Monday night at the Kennedy Center concert hall in Washington, D.C. 

Earlier on, he made a point about diversity and what he calls "the edge effect," something that happens when two different kinds of creative artists collaborate with each other. He illustrated it with a biological example, stating that where two ecological systems meet is where there is the most diversity and the most new forms of life, which come about because of the influence of the systems on each other.
