West African giraffe
Evolutionary history
Most captive giraffes from northwestern Africa are in French zoological parks, a result of the history of French colonialism in what was French West Africa. Those giraffes were formerly treated as G. c. peralta. However, since genetic analysis revealed that only giraffes to the west of Lake Chad belong to this subspecies, the populations in European zoos are in fact Kordofan giraffes (G. c. antiquorum). The West African giraffe is more closely related to the giraffes of East Africa than to those of Central Africa. Its ancestor may have migrated from East to North Africa during the Quaternary and then to West Africa with the development of the Sahara desert. At its largest, Lake Chad may have acted as a barrier between West African and Kordofan giraffes during the Holocene.
