She introduces us to renowned futurists like Stewart Brand and scientists like George Church, who are harnessing the powers of CRISPR gene editing in the hopes of “reviving” extinct passenger pigeons, woolly mammoths, and heath hens. She speaks with Nikita Zimov, who together with his eclectic father Sergey, is creating Siberia’s Pleistocene Park—a daring attempt to rebuild the mammoth’s ancient ecosystem in order to save earth from climate apocalypse. Through interviews with these and other thought leaders, Wray reveals the many incredible opportunities for research and conservation made possible by this emerging new field.But we also hear from more cautionary voices, like those of researcher and award-winning author Beth Shapiro (How to Clone a Woolly Mammoth) and extinction philosopher Thomas van Dooren. Writing with passion and perspective, Wray delves into the larger questions that come with this incredible new science, reminding us that de-extinction could bring just as many dangers as it does possibilities. What happens, for example, when we bring an “unextinct” creature back into the wild? How can we care for these strange animals and ensure their comfort and safety—not to mention our own? And what does de-extinction mean for those species that are currently endangered? Is it really ethical to bring back an extinct passenger pigeon, for example, when countless other birds today will face the same fate?By unpacking the many biological, technological, ethical, environmental, and legal questions raised by this fascinating new field, Wray offers a captivating look at the best and worst of resurrection science.

    When the Branch Davidian compound in Waco caught fire, when a terrorist-flown plane crashed into the Pentagon, and when mass graves were uncovered in Croatia, the authorities called Owsley. Through cutting-edge science, instinctive artistry, and dogged tenacity, Owsley painstakingly rebuilds the skeleton, and helps identify it and determine the cause of death.A curator for the Smithsonian's Museum of Natural History, Doug Owsley has handled over ten thousand human skeletons, more than anyone else in America. He has worked with America's historic skeletons, from, colonial Jamestown burials to Plains Indians to Civil War soldiers to skeletons tens of thousands of years old.That includes the Kennewick Man, a 9,600-year-old human skeleton found in shallow water along the banks of Washington State's Columbia River. It was a skeleton that would turn Owsley's life upside down.Days before Owsley was scheduled to begin studying the skeleton, the U.S. Army Corps of Engineers seized it and announced they would repatriate Kennewick Man, burying his bones on the land of the Native American tribes who claimed him. Along with seven of America's leading scientists, Owsley sued the U.S. government over custody. At stake was a wide body of knowledge about our past and our history that would be lost forever if the bones were reburied. For six years, Owsley fought a legal and political battle that put everything at risk, jeopardizing his career and his reputation.

    In 1848, the East India Company engaged him to make a clandestine trip into the interior of China - territory forbidden to foreigners - to steal the closely guarded secrets of tea. For centuries, China had been the world's sole tea manufacturer. Britain purchased this fuel for its Empire by trading opium to the Chinese - a poisonous relationship Britain fought two destructive wars to sustain. The East India Company had profited lavishly as the middleman, but now it was sinking, having lost its monopoly to trade tea. Its salvation, it thought, was to establish its own plantations in the Himalayas of British India. There were just two problems: India had no tea plants worth growing, and the company wouldn't have known what to do with them if it had. Hence Robert Fortune's daring trip. The Chinese interior was off-limits and virtually unknown to the West, but that's where the finest tea was grown - the richest oolongs, soochongs and pekoes. And the Emperor aimed to keep it that way.
