Could chimpanzees raised in captivity be suffering because of it? Although there are immediate welfare consequences of removing infant chimps from their mothers, there's been very little research done on the long-term impacts of this early life experience. Now, scientists have taken a closer look at the behavioral and social impacts that chimps experience when raised in captivity.
In this case, the scientists studied 60 chimps with a range of personal histories over the course of 14 months. All of the chimpanzees were living in zoos and 35 of them were either former pets or performers.
