Joshua was a rhesus macaque born in a "monkey colony" maintained for research on primate development and reproduction. The monkey colony was part of the Carnegie Institution's Department of Embryology from 1925-1971, and the collections are now housed at the National Museum of Health and Medicine. Researchers were able to use data on how monkeys develop to better interpret data on how another primate, humans, develop.
The rhesus macaque species has served as a useful animal model for research on human physiology and disease, including the discovery of the namesake Rh factor in blood.
