Nature 22 August 2013 The tortoise knows it’s what’s inside that counts In our Nature column, poet Ruth Padel considers the tortoise - the animal which refuses to be read.

The islands were never part of any continent, so their animals evolved without the presence of human beings. There are no predators except hawks. Nothing tells these creatures how dangerous we are. You step into Eden, where the sea lion lies down with the iguana, you clear your boots of harmful non-native seeds and avoid treading on blue-footed boobies – but you are bringing in the human stain. The 16th-century Spanish who discovered the islands called them Galapagos after the giant tortoises that, 300 years later, helped Charles Darwin work out how individuals and species change to fit each particular environment. “The vice-governor,” he said, “declar[ed] that the tortoises differed on different islands . . . he could with certainty tell from which island any one was brought.” When the ornithologist John Gould studied birds Darwin brought back, and told him the finches and mockingbirds from different islands differed, too, he realised how important this was. But of all Galapagos wildlife, their eponymous giant tortoises were the most destroyed by human goings-on. Pirates and whalers caught them and stacked them in the ships’ holds, where they survived miserably, without food or drink, for a year. Their meat was “more delicious than chicken or beef”. Settlers introduced goats, pigs and rats; these ate tortoise eggs and destroyed tortoise habitat. Giant tortoises nearly died out: half of the original 15 subspecies are now extinct, including the Pinta Island tortoise, whose last representative, known as Lonesome George, died in 2012. But though human beings destroy, they also sometimes save. Since the 1960s, in a parable of exemplary conservation and one of the most successful breed-and-release programmes in the world, the Galapagos National Park has brought seven subspecies back to viable numbers. They collect the eggs; breeding centres hatch and raise the young through their vulnerable early years, and then release them. Once upon a time (says an African story), God told the animals he would award a prize for the best dance. Lion shook sparks from his mane, Ostrich perfected a feathery high kick, Impala leaped about in arabesques, Giraffe improvised a dreamy sarabande. Tortoise just drew in his head, legs and tail. “You didn’t try,” jeered the others, but God gave the prize to him. “You danced for yourselves,” God told the rest, “but Tortoise’s dance was inside himself. He danced only for me.” A tortoise refuses to be read: God knows what’s going on inside. In a lovely poem by Mark Doty, children rush excitedly into a grown-ups’ dinner party carrying a wild tortoise. They know this creature can “make night/anytime he wants, so perhaps/he feels at the center of everything,/as they do”. They hope “he might, like God, show his face”. They show him to the adults, so they can experience his “prayer,/the single word of the shell,/which is no”. As a symbol, the tortoise links identity to privacy. So do islands. The remaining subspecies of Galapagos tortoise now symbolise the ways in which we, too, sometimes say no. The Galapagos National Park has got rid of human-introduced feral goats, pigs and rats and is re-tortoising islands where tortoises used to live. No more waiting in the hold to be dinner: the giants are back in the habitat that evolution gave them. Their slow dance may seem only for them, but it is dispersing native seeds and trampling vegetation so that light penetrates and seeds germinate. They are ecosystem engineers, bringing the habitat back to how it was before humans came. We benefit, too. We can stand like Adam in Eden and watch.
