EARLIER THIS YEAR, David Gokhman summoned a ghost. Gokhman, then a Ph.D. student at the Hebrew University of Jerusalem, was attempting to piece together the skeleton of an enigmatic ancient human known as a Denisovan. But while the Denisovans likely lived in Asia for tens of thousands of years, researchers have only found meager fossil traces—a pinky bone, a skull fragment, a fractured jaw, and a few teeth. To give these specters form, Gokhman instead turned to the most compelling trace of their existence: their ancient DNA.
