A pride of captive lions descended from the private menagerie of Emperor Haile Selassie of Ethiopia is genetically distinct from all other lions of Africa, a study has found.
The Ethiopian lion has a distinctive dark mane and is slightly smaller than other African lions.
Now an analysis of its DNA has revealed the Ethiopian lion is also a distinct breed.
It is thought that there may be less than a few hundred Ethiopian lions living in the wild and scientists are urging that their unique genetic makeup should be preserved by a captive-breeding programme.
DNA tests on 15 of the 20 Ethiopian lions kept in Addis Ababa Zoo have revealed that they form a separate genetic group from the lions of east Africa and southern Africa, said Dr Michael Hofreiter of the University of York.
