What was special about the discovery of handclasp grooming in chimpanzees?
A research collaboration between the Gonzaga University and the Max Planck Institute shows that the way in which chimpanzees groom each other depends on the community to which they belong. Specifically, it is the unique handclasp grooming behaviour that reveals this local difference.
What does grooming behavior accomplish for the chimpanzees?

Why is grooming important to non human primates?

Why do female monkeys groom each other?

Is grooming an innate behavior?
Self-grooming in animals is an innate behaviour that is involved in hygiene maintenance and other physiologically important processes, including thermoregulation, social communication and de-arousal1–6.
