Data from: Personality links with lifespan in chimpanzees

Life-history strategies for optimizing individual fitness fall on a
spectrum between maximizing reproductive efforts and maintaining physical
health over time. Strategies across this spectrum are viable and different
suites of personality traits have evolved to support these strategies.
Using personality and survival data from 538 captive chimpanzees (Pan
troglodytes) we tested whether any of the dimensions of chimpanzee
personality - agreeableness, conscientiousness, dominance, extraversion,
neuroticism, and openness - were associated with longevity, an attribute
of slow life-history strategies that is especially important in primates,
given their relatively long lives. We found that higher agreeableness was
related to longevity in males, with weaker evidence suggesting that higher
openness is related to longer life in females. Our results link the
literature on human and nonhuman primate survival, and suggest that for
males, evolution has favored the protective effects of low aggression and
high quality social bonds.
