Field biologists studying large and charismatic animals wanted to know if their own species had genetic problems. I listened carefully to stories of koalas in Australia, giant pandas in China, black-footed ferrets in the Midwest, elephants, rhinos, and leopards in Africa, and orangutans in Asia--all threatened or endangered species attended by packs of worried field biologists. If cheetahs paid a price for their brush with extinction, did these species suffer the same?
