Everyone in the group helps rear the young!
The Barbary Macaque is a monkey that only lives in North Africa and British Gibraltar. In addition to the mother, all adult males in the group rear the young together. Male adults have also been known to pacify a conflict-waging male by showing that he is holding a newborn baby. These monkeys avoid unnecessary conflict among themselves while caring for their young.

Trees were cut, and then came livestock...
The Barbary Macaque is rapidly declining due to home and food loss caused by logging activity and sheep pasturage. Still, because of their nature to live in groups, it is not an easy task for humans to breed them into steadier numbers and release them into wilderness. This is because breeders would need to move the whole group, which to the monkey, is an entire society. The only way to stop them from becoming extinct is to create forests where they can live in peace.
