Baby Fae body began generating isohaemagglutinins, but a suitable donor could not be found in time. Prior to the procedure, no infant heart transplant—even with human hearts—had been successfully performed due to a lack of infant human hearts. To address this issue, Bailey had become a pioneer in the research of cross-species heart transplants, which had included "more than 150 transplants in sheep, goats, and baboons". Multiple surgeons had previously experimented with baboon heart implants, leading some to speculate even that baboons could be farmed in the future for such purposes. When asked why he had picked a baboon over a primate
Kinda baboon about the size of adult females of other baboon species. The Kinda baboon is also characterized by its short face (relating to its small size), pink circles around its eyes, and its infants are frequently born with white instead of black hair. Baboons in between the size of the Kinda baboon and the yellow baboon are present in northeastern Zambia, and possibly in northern Malawi and southwestern Tanzania as well. Such a broad area of intergradation has been taken as evidence of substantial genetic exchange between the two taxa. The Kinda baboon appears to live in large (perhaps over 100
