About 4,000 years ago, the last of Earth's woolly mammoths died out on a lonely Arctic Ocean island off the coast of Siberia, a melancholy end to one of the world's charismatic Ice Age animals. But what doomed this last mammoth population on Wrangel Island? A new genomic analysis deepens the mystery.
