David Reich Unearths Human History Etched in Bone

Carl Zimmer in the New York Times:

In less than three years, Dr. Reich’s laboratory has published DNA from the genomes of 938 ancient humans — more than all other research teams working in this field combined. The work in his lab has reshaped our understanding of human prehistory.

“They often answer age-old questions and sometimes provide astonishing unanticipated insights,” said Svante Paabo, the director of the Max Planck Institute of Paleoanthropology in Leipzig, Germany.

Dr. Reich, Dr. Paabo and other experts in ancient DNA are putting together a new history of humanity, one that runs in parallel with the narratives gleaned from fossils and written records. In Dr. Reich’s research, he and his colleagues have shed light on the peopling of the planet and the spread of agriculture, among other momentous events.

In a book to be published next week, “Who We Are and How We Got Here,” Dr. Reich, 43, explains how advances in DNA sequencing and analysis have helped this new field take off.

“It’s really like the invention of a new scientific instrument, like a microscope or a telescope,” he said. “When an instrument that powerful is invented, it opens up all these horizons, and everything is new and surprising.”
