Ellsworth Wareham after the first such procedure was performed. Leonard Bailey, the surgeon who transplanted a baboon heart into a baby at Loma Linda University in 1984, trained under Wareham as a medical student in the late 1960s. The child, Baby Fae, was born prematurely with hypoplastic left heart syndrome and Bailey’s surgery made international headlines. Loma Linda, Wareham's home town has been described as USA's only Blue Zone, an area where the longevity is appreciably higher than the national average and one of the four places in the world to have a substantial proportion of humans live past 100 years.

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
