"It is a bit puzzling why we see different forms of helping in bonobos and chimpanzees," Krupenye said. This stands in contrast to chimpanzees, which typically share tools and other items but not food. "It's exceedingly rare for primates to actively hand monopolizable food to others."Īll in all, this work revealed that bonobos shared food but refused to share toys and tools. "Food sharing has been documented in primates and especially bonobos, but the vast majority of instances of food sharing in other species involve tolerating another individual taking food from you," Krupenye said. The apes also did not share the rocks, but they did share nuts. The scientists found the bonobos did not share the stick, although they often retrieved it and even playfully teased experimenters with it.

In the other, 10 pairs of bonobos could interact through a mesh window and a hole, and one member of each pair was given two rocks, while the other was given five palm nuts, a snack they could crack with their teeth but preferred hammering open with rocks. In one, 18 bonobos were tested one at a time to see whether they would retrieve and share an out-of-reach stick for a human experimenter that motioned toward and called out for it. But bonobos are equally as closely related to humans as are chimpanzees and, therefore, are just as important species for comparison." To see how much bonobos share, researchers conducted two experiments. "And most of that theory is based on comparisons between chimpanzees and humans. "There are huge debates among researchers about the evolutionary origins of human cooperation," says study lead author Christopher Krupenye, an evolutionary anthropologist at the University of St. To shed light on the evolutionary roots of sharing, researchers investigated bonobos. The other side says that although the great apes can share in specific ways, only humans are versatile enough to share both food and other items. One argument suggests that only humans are helpful enough to share food. Yet scientists have debated whether humans are unique compared with the great apes when it comes to helping others. It helped ensure that vital needs were reliably met, and this food helped feed ever-larger brains. And the emergence and development of this sharing likely helped play a key role in human evolution. Although nature is typically seen as "red in tooth and claw," humans are often willing to voluntarily share resources with others. This research underscores that sharing is not unique to humans, but the breadth and flexibility of this sharing may be. New findings now reveal they also share food with others, but not toys or tools.
