“Church’s woolly mammoth research is just one of several de-extinction projects—there are about ten underway now—that aim to use genetics to restore lost species. In her book “The Re-Origin of Species,” the Swedish science journalist Torill Kornfeldt travels the world meeting the scientists and conservationists involved in this movement. In California, she talks with Ben Novak, a scientist obsessed with bringing back the passenger pigeon—a bird that once travelled in flocks that were so giant and dense, Novak tells her, that they “swept through the landscape, with the same effect as forest fires.” In upstate New York, a researcher is working toward restoring the American chestnut, which was decimated by blight in the late eighteen-hundreds. Until then, chestnuts were so prevalent in the eastern half of the United States that, when their white blossoms fell in the spring, the hillsides looked like they were covered in snow; in the fall, their sweet, starchy nuts served as a free, abundant harvest. At Australia’s Sea Simulator aquarium, resurrection scientists are working on coral, which faces an existential threat from the rapid warming and acidifying of ocean waters.
