Social bonds of female baboons enhance infant survival.

摘要: Among nonhuman primates, females often form strong bonds with kin and other group members. These relationships are thought to have adaptive value for females, but direct effects of sociality on fitness never been demonstrated. We present 16 years behavioral data from a well-studied population wild baboons, which demonstrate that adult is positively associated infant survival, an important component variation in female lifetime fitness. The survival independent the dominance rank, membership, environmental conditions. Our results consistent evidence social support has beneficial human health well-being across life span. For humans value.
