  • When a new alpha male takes over, female capuchin monkeys are more likely to lose their offspring to infanticide if they have an extensive network of social contacts than if they don't. This new finding suggests sociable primates don't necessarily fare better than non-sociable ones when it comes to raising offspring. Group-living mammals have plenty to gain from being sociable, says Urs Kalbitzer at the University of Calgary in Canada. They can have better access to food and more protection from predators, as they often take up a position near the center of the group. These advantages should help the most sociable females raise more infants to adulthood.
