The sad story of an orphan mountain gorilla has a somewhat happy ending. Rescued as a 4-year-old from poachers in 2007, Kaboko was raised in a gorilla orphanage in the Democratic Republic of the Congo (DRC). He got sick and died at age 9, never having the opportunity to breed and help the mountain gorillas recover from the low numbers that threaten their existence. But with his blood and that of six others, researchers have now delved into the history and health status of these endangered animals and concluded their fate may be less dire than some have feared.
