Chimpanzee Moms' Social Bonds Boost Baby Survival

A recent study on wild eastern chimpanzees reveals that female chimps with strong social connections are more likely to raise surviving offspring. The research, published in iScience, highlights the importance of female sociality in ensuring infant survival, even in the absence of close kin. The study found that social bonds among females, rather than kinship or male relationships, play a crucial role in offspring survival.

In chimpanzee communities, strong social ties are crucial for the survival of both adults and their offspring. A study of wild eastern chimpanzees from Gombe National Park revealed that female chimpanzees who were more socially connected with other females before giving birth were more likely to raise surviving offspring. This survival advantage held true even in the absence of close kin, as female chimpanzees are known to disperse from their maternal group at sexual maturity.

Researchers analyzed behavioral data from 37 mothers and their 110 offspring over three decades, focusing on association and grooming behaviors. Females with stronger social connections had a higher chance of raising their offspring to their first year, with the effect persisting until age five. The study found that the key to offspring survival was having social connections with other females, rather than close kin or bonds with males.

The mechanism behind this survival benefit remains unclear, but it could involve reduced harassment, increased help in defending resources, or improved overall condition during pregnancy. The study highlights the importance of social relationships in supporting female chimpanzees and their offspring, emphasizing the value of collaboration and cooperation in social species.
