Ferris Jabr writes: Many years ago, while wandering through Amboseli National Park in Kenya, an elephant matriarch named Echo came upon the bones of her former companion Emily. Echo and her family slowed down and began to inspect the remains. They stroked Emily’s skull with their trunks, investigating every crevice; they touched her skeleton gingerly with their padded hind feet; they carried around her tusks. Elephants consistently react this way to other dead elephants, but do not show much interest in deceased rhinos, buffalo or other species. Sometimes elephants will even cover their dead with soil and leaves.
What is going through an elephant’s mind in these moments? We cannot explain their behavior as an instinctual and immediate reaction to a dying or recently perished compatriot. Rather, they seem to understand—even years and years after a friend or relative’s death—that an irreversible change has taken place, that, here on the ground, is an elephant who used to be alive, but no longer is. In other words, elephants grieve.
Such grief is but one of many indications that elephants are exceptionally intelligent, social and empathic creatures. After decades of observing wild elephants—and a series of carefully controlled experiments in the last eight years—scientists now agree that elephants form lifelong kinships, talk to one another with a large vocabulary of rumbles and trumpets and make group decisions; elephants play, mimic their parents and cooperate to solve problems; they use tools, console one another when distressed, and probably have a sense of self (See: The Science Is In: Elephants Are Even Smarter Than We Realized)
All this intellect must emerge, in one way or another, from the elephant brain—the largest of any land animal, three times as big as the human brain with individual neurons that seem to be three to five times the size of human brain cells. [Continue reading…]
