China’s Père David’s deer was nearly gone in the late 1800s. Just 18 deer—the very last of their kind—were brought into captivity after the rest had been hunted to extinction. When 11 of the deer reproduced, the species had a chance. Today, after centuries of reintroductions and breeding under human care, the population sits at around 3,000.
