Scientists have long thought that it emerged three billion years ago in the ocean -- until astrobiologist Tara Djokic and her team made an unexpected discovery in the western Australian desert. Learn how an ancient rock found near a hot volcanic pool is shifting our understanding of the origin-of-life puzzle.
