Social Networking Monkeys More Popular in Their Groups

Social networking doesn't just empower the human race, it also benefits monkeys, a study reveals. Researchers have found that the power of social networks didn't start just in the digital age and monkeys, who have strong social networks, adapt to new method very quickly.

The researchers, led by Andrew Whiten of the University of St Andrews, made the discovery by combining social network analysis with more traditional social learning experiments.

By bringing the two together, they offer what they say is the first demonstration of how social networks may shape the spread of new cultural techniques. It's an approach they hope to see adopted in studies of other social animals.

Whiten said that their study shows that innovations do not just spread randomly in primate groups but, as in humans, are shaped by the monkeys' social networks.

Whiten, along with Nicolas Claidiere, Emily Messer, and William Hoppitt, traced the monkeys' social networks by recording which monkeys spent time together in the vicinity of "artificial fruits" that could be manipulated to extract tempting food rewards.

Sophisticated statistical analysis of those data revealed the monkeys' social networks, with some individuals situated at the heart of the network and others more on the outside.

The researchers rated each of the monkeys on their "centrality," or social status in the network, with the highest ratings going to monkeys with the most connections to other well-connected individuals.

The artificial fruits could be opened in two different ways, either by lifting a little hatch on the front or by pivoting it from side to side. The researchers trained the alpha male in one group of monkeys on the lift technique, while the leader in another group was trained on the pivot method.

They then sent them back to their groups and watched to see how those two methods would catch on in the two groups.

More central monkeys with the strongest social ties picked up the new methods more successfully, the researchers found. They were also more likely than peripheral monkeys to learn the method demonstrated by their trained alpha leaders.

Whiten said the squirrel monkeys are a good species for these studies because of their natural inquisitiveness. They also lead rather intense social lives.

The researchers now hope to extend their studies to focus on the squirrel monkeys in different contexts-while foraging, moving, and resting, for example-and how those contexts might influence the spread of innovations. They suspect they might even find evidence for different monkey subcultures.

The study has been published in Current Biology, a Cell Press publication.
