Due to hybridization between different baboon ("Papio") populations across Africa, authors have occasionally grouped the entire radiation as a single species, the hamadryas baboon, "Papio hamadryas". Arbitrary boundaries were then used to separate the populations into subspecies. Other authors considered the chacma baboon a subspecies of the yellow baboon, "Papio cynocephalus", though it is now recognised as a separate species, "Papio ursinus". The chacma baboon has two or three subspecies, depending on which classification is followed. Grubb et al. (2003) listed two subspecies, while Groves (2005) in Mammal Species
