DO ELEPHANTS KNOW THAT MAN IS DETROYING THEM?



Elephants, we all know, are in peril. We humans are waging what amounts to a war against them because they have something we want and cannot make on our own: ivory.

Earlier this month, we learned that the West African country of Gabon has lost more than half its elephants—11,000—in the last ten years alone.

People are shooting, poisoning, and spearing the animals at such a rate across the continent that some scientists already consider them "ecologically extinct." There are now fewer than 500,000 wild African elephants—maybe no more than half that number—and barely 32,000 Asian elephants.

They cannot fight against us; they cannot win this battle.

And the horror of what is happening to them is surely compounded in their minds by the empathy they feel for one another—an emotion that scientists have at last been able to demonstrate experimentally in elephants.

Elephant Empathy: One Example After Another

But why did it take an experiment? Research on elephants is full of examples of the animals apparently behaving empathetically—recognizing and responding to another elephant's pain or problem. Often, they even make heroic efforts to assist one another.

In Kenya, researchers have watched mother elephants and other adult females help baby elephants climb up muddy banks and out of holes, find a safe path into a swamp, or break through electrified fences.

Scientists have spotted elephants assisting others that are injured, plucking out tranquilizing darts from their fellows, and spraying dust on others' wounds.

A two-year-old African elephant baby climbs on the back of his mother in the Nyiregyhaza Animal Park in Budapest, Hungary, one day after the mother died. The baby stayed near the lifeless body of his mother for 14 hours after her death, and wept after the body was removed.

And on at least one occasion, researchers have watched an elephant struggle to help a dying friend, lifting her with her tusks and trunk, while calling out in distress.

Aren't such accounts sufficient for scientists to say unequivocally that elephants, like us, are empathetic beings?

Sadly, no. For various reasons—some scientific, some philosophical, some religious, some economic—we have set the bar exceedingly high for recognizing emotions (other than anger and fear) in other animals.

Saying absolutely that elephants (or other animals) are empathetic requires an experiment, something that is difficult to do in the wild. Experiments mean that these are not chance observations—the results are repeatable.

To show that elephants experience the same emotions another is feeling, scientists watched captive Asian elephants in a park in Thailand. They noted when one elephant was upset by something, such as by a snake in the grass, and they recorded her behaviors to see if there was a pattern.

There was. In response to a stressful event, an elephant flares out her ears, erects her tail, and sometimes makes a low rumble. Scientists watching elephants in the wild have reported the same behaviors. (See "Surprise: Elephants Comfort Upset Friends.")

Emotional Contagion

Both in the wild and in this captive study, researchers have watched other, nearby elephants react to the other elephant's distress by acting in exactly the same way. Scientists call this emotional contagion.

The elephants also ran to stand beside their friend, touched her with their trunks to soothe her, and made soft chirping sounds. Sometimes one would even put her trunk inside the other's mouth, a behavior elephants find particularly comforting, the researchers say.

We do something very similar when watching a scary movie with a friend. When the main character is threatened, we feel his fear. Our hearts race, we may tremble, and for reassurance, we reach for our friend's hand.

The researchers also recorded what the elephants did when they were in the same locations with their same friends nearby, but nothing stressful occurred. In those moments, none of the elephants acted in an empathetic way.

By comparing the two types of events—stressful versus nonstressful—the scientists were able to say that "emotional contagion" occurs only when an elephant sees another in distress.

Some scientists may still argue that this is not sufficient evidence for true empathy, that the experiment doesn't reveal what's going on in an elephant's mind when she rushes to aid a friend or worries over a dying companion.

But the fact that elephants make any effort at all on another elephant's behalf suggests that they are at the very least highly aware and emotional beings, concerned in some manner for each other. FULL STORY HERE
