A crowded mountain can make silverback gorillas more violentA crowded mountain can make silverbacks more violent, scientists say. Mountain gorillas spend most of their time sleeping, chomping leaves and wild celery stalks, and grooming each other’s fur with long, dexterous fingers. Researchers who analyzed 50 years of demographic and behavioral data from Rwanda found that as the number of gorilla family groups living in a habitat increased, so did the number of violent clashes among them.
