Pakistan's 'Burushaski' Language Finds New Relatives

Robert Siegel talks to professor Ilija Casule of Macquarie University in Sydney, Australia. His research shows that a language spoken by about 90,000 people in a remote area of Pakistan is Indo-European in origin. He explains how 20 years of research has tied this isolated group of people to a migration that started in the Balkans and moved East 3,000 years ago.
