Frans de Waal Writes About The Better Side of Chimpanzees, The Age Of Empathy

A pioneer in primate studies, Frans de Waal sees our better side in chimps, especially our capacity for empathy. In his research, Dr. de Waal has gathered ample evidence that our ability to identify with another's distress -- a catalyst for compassion and charity -- has deep roots in the origin of our species. It is a view independently reinforced by recent biomedical studies showing that our brains are built to feel another's pain.

Like tuning forks, we reflexively respond to others' moods. We can weep at the plight of people we have never met or, spellbound by fiction, become caught up in the lives of people who never existed. Indeed, we may be hard-wired for empathy, University of Chicago researchers who studied children's neural responses to others reported last year. "It starts on day one, when a baby cries because it hears another baby cry," says Dr. de Waal.

In his new book -- "The Age of Empathy" -- Dr. de Waal, director of Living Links Center at Emory University's Yerkes National Primate Research Center in Atlanta, traces the origins of our ability to put ourselves in another's place. Drawing on his experiments and studies by other animal behaviorists, he highlights how chimpanzees and other primates console each other, prefer to share, and nurse the injured. There are no fossils of feelings, but as our closest living relatives, Dr. de Waal believes these primates are reminders of empathy's antiquity.

Despite our genetic similarity to chimpanzees, evolution has taken us on different paths since our ancestors diverged more than six million years or so ago. Our brains today are quite unlike a chimp's in size, organization and cellular complexity. A chimp's brain weighs as much as a can of baked beans -- only a quarter the average human weight. Our cerebral cortex, the brain's most highly evolved region, is three times larger than a chimp's. Our mind's emotional intelligence requires all that extra gray matter. And some neuroscientists consider empathy a uniquely human virtue.

Even so, Dr. de Waal contends that empathy, sympathy and compassion are traits shared by every species with a rudimentary capacity for self-awareness. While chimps can be combative and violent, they more often comfort and help each other. Capuchin monkeys enjoy giving to others. Elephants and dolphins aid companions in need. Whales can display something akin to gratitude. Even mice appear to have an ability to sense what their cage-mates are experiencing, says a recent study by researchers at McGill University.

"The old remains present in the new," Dr. de Waal says. "This is relevant to the story of empathy because it means that even our most thoughtful reactions to others share core processes with the reactions of young children, other primates, elephants, dogs and rodents."

"All mammals have some degree of it, and I think the origin is in maternal care," Dr. de Waal says. "I think mammals need a mechanism like this because a female needs to be very sensitive to emotional signals that come from offspring. We just have a more powerful imagination and that amplifies our capacity for empathy."

Empathy draws us into the life of another's mind. Synapses fire to marshal sensory cues, muster memories and weave intuitions that our conscious minds could never articulate. As a visceral response to others, empathy can manifest in unexpected ways -- through contagious yawning, for instance.

Most people can't help but yawn reflexively when someone else starts doing it first. No one knows why, but researchers at the State University of New York recently learned that people better able to identify with another's state of mind also yawn more readily in response to others. Children with autism -- a condition characterized by an inability to interact socially -- don't catch yawns, scientists at the University of London's Birkbeck College reported in 2007.

But monkeys do. Chimpanzees will yawn when shown a computer animation of another monkey yawning, Dr. de Waal and his colleagues reported earlier this month in the Proce.
