Oct. 9, 2018 (Phys.org) -- Male chimps that are less aggressive and form strong social bonds tend to live longer, research suggests.
A study of hundreds of captive chimpanzees showed that males that get along well with others -- by being sensitive, protective and cooperative -- outlived their less amiable peers.
The team, led by researchers at the University of Edinburgh, found that, contrary to studies of humans and other primates, being more extroverted, conscientious or neurotic had no impact on chimpanzee's longevity.
Extraversion is frequently associated with longer life in other nonhuman primates, while conscientiousness and neuroticism are associated with longer and shorter life, respectively, in humans.
