For chimpanzees born in a lab, separation from their mother is just the beginning of the trauma. Baby chimpanzees who are only months old may be sent into research. Others are not “put to work” for several years.
There is usually little, if any, transition from the nursery to a research unit. In the nursery, baby chimpanzees are typically handled by human caregivers, housed in pairs or small groups, and given bottles, toys, and opportunities to play. Most research protocols prevent any of this comfort. The sudden change impacts them in every way.
