Despite increasing interest in genocide on the part of psychologists and biologists as well as some lay people, basic questions about it remain disputed. Do any animals routinely kill members of their own species, or is that a human invention without animal precedents? Throughout human history, has genocide been a rare aberration, or has it been common enough to rank as a human hallmark along with art and language? Is its frequency now increasing, because modern weapons permit push-button genocide and thereby reduce our instinctive inhibitions about killing fellow humans? Why have so many cases attracted so little attention? Are genocidal killers abnormal individuals, or are they normal people placed in unusual situations? To understand genocide, we cannot proceed narrowly but must draw on biology, ethics, and psychology. Consequently our exploration of genocide will begin by tracing its biological history, from our animal ancestors to the Twentieth Century. After asking how killers have reconciled genocide with their ethical codes, we can examine its psychological effects on the perpetrators, surviving victims, and onlookers. But before we search for answers to these questions, it is useful to start with the extermination of the Tasmanians, as a case study typical of a broad class of genocide. Tasmania is a mountainous island similar in area to Ireland and lying 200 miles off Australia's southeast coast. When discovered by Europeans in 1642, it supported about 5,000 hunter-gatherers related to the Aborigines of the Australian mainland and with perhaps the simplest technology of any modern peoples. Tasmanians made only a few types of simple stone and wooden tools. Like the mainland Aborigines, they lacked metal tools, agriculture, livestock, pottery, and bows and arrows. Unlike the mainlanders, they also lacked boomerangs, dogs, nets, knowledge of sewing, and ability to start a fire.
Since the Tasmanians' sole boats were rafts capable of only short journeys, they had had no contact with any other humans since the rising sea level cut off Tasmania from Australia 10,000 years ago. Confined to their private universe for hundreds of generations, they had survived the longest isolation in modern human history—an isolation otherwise depicted only in science fiction. When the white colonists of Australia finally ended that isolation, no two peoples on Earth were less equipped to understand each other than were Tasmanians and whites. The tragic collision of these two peoples led to conflict almost as soon as British sealers and settlers arrived around 1800. Whites kidnapped Tasmanian children as labourers, kidnapped women as consorts, mutilated or killed men, trespassed on hunting grounds, and tried to clear Tasmanians off their land. Thus, the conflict quickly focused on lebensraum, which throughout human history has been among the commonest causes of genocide. As a result of the kidnappings, the native population of northeast Tasmania in November 1830 had been reduced to seventy-two adult men, three adult women, and no children. One shepherd shot nineteen Tasmanians with a swivel gun loaded with nails. Four other shepherds ambushed a group of natives, killed thirty, and threw their bodies over a cliff remembered today as Victory Hill.
Naturally, Tasmanians retaliated, and whites counter-retaliated in turn. To end the escalation, Governor Arthur in April 1828 ordered all Tasmanians to leave the part of their island already settled by Europeans. To enforce this order, government-sponsored groups called roving parties, and consisting of convicts led by police, hunted down and killed Tasmanians. With the declaration of martial law in November 1828, solidiers were authorized to kill on sight any Tasmanian in the settled areas. Next, a bounty was declared on the natives: five British pounds for each adult, two pounds for each child, caught alive. 'Black catching', as it was called because of the Tasmanians' dark skins, became big business pursued by private as well as official roving parties. At the same time a commission headed by William Broughton, the Anglican archdeacon of Australia, was set up to recommend an overall policy towards the natives. After considering proposals to capture them for sale as slaves, poison or trap them, or hunt them with dogs, the commission settled on continued bounties and the use of mounted police. In 1830 a remarkable missionary, George Augustus Robinson, was hired to round up the remaining Tasmanians and take them to Flinders Island, thirty miles away. Robinson was convinced that he was acting for the good of the Tasmanians. He was paid 300 pounds in advance, 700 pounds on completing the job. Undergoing real dangers and hardship, and aided by a courageous native woman named Truganini, he succeeded in bringing in the remaining natives—initially, by persuading them that a worse fate awaited them if they did not surrender, but later at gunpoint. Many of Robinson's captives died en route to Flinders, but about 200 reached there, the last survivors of the former population of 5,000.
On Flinders Island Robinson was determined to civilize and christianize the survivors. His settlement was run like a jail, at a windy site with little fresh water. Children were separated from parents to facilitate the work of civilizing them. The regimented daily schedule included Bible reading, hymn singing, and inspection of beds and dishes for cleanliness and neatness. However, the jail diet caused malnutrition, which combined with illness to make the natives die. Few infants survived more than a few weeks. The government reduced expenditures in the hope that the natives would die out. By 1869 only Truganini, one other woman, and one man remained alive. These last three Tasmanians attracted the interest of scientists, who believed them to be a missing link between humans and apes. Hence when the last man, one William Lanner, died in 1869, competing teams of physicians, led by Dr George Stokell from the Royal Society of Tasmania and Dr W.L. Crowther from the Royal College of Surgeons, alternately dug up and reburied Lanner's body, cutting off parts of it and stealing them back and forth from each other. Dr Crowther cut off the head, Dr Stokell the hands and feet, and someone else the ears and nose, as souvenirs. Dr Stokell made a tobacco pouch out of Lanner's skin.
Before Truganini, the last woman, died in 1876, she was terrified of similar post-mortem mutilation and asked in vain to be buried at sea. As she had feared, the Royal Society dug up her skeleton and put it on public display in the Tasmanian Museum, where it remained until 1947. In that year the Museum finally yielded to complaints of poor taste and transferred Truganini's skeleton to a room where only scientists could view it. That too stimulated complaints of poor taste. Finally, in 1976—the centenary year of Truganini's death—her skeleton was cremated despite the Museum's objections, and her ashes were scattered at sea as she had requested.
While the Tasmanians were few in number, their extermination was disproportionately influential in Australian history, because Tasmania was the first Australian colony to solve its native problem and achieved the most nearly final solution. It had done so by apparently succeeding in getting rid of all its natives. (Actually, some children of Tasmanian women by white sealers survived, and their descendants today constitute an embarrassment to the Tasmanian government, which has not figured out what to do about them.) Many whites on the Australian mainland envied the thoroughness of the Tasmanian solution and wanted to imitate it, but they also learned a lesson from it. The extermination of the Tasmanians had been carried out in settled areas in full view of the urban press, and had attracted some negative comment. The extermination of the much more numerous mainland Aborigines was instead effected at or beyond the frontier, far from urban centres.
