...year and a half since Scottish embryologist Ian Wilmut presented Dolly, the cloned sheep, to an astonished world, ethicists and policymakers have been struggling with the unsettling implications of his research. Could scientists use Wilmut's method to clone not just sheep but also billionaires, basketball players and bodies grown for spare parts? Should medical entrepreneurs be allowed to pursue cloning wherever it leads? Or should the government step in now and outlaw it before it starts...
Extraordinary claims, scientists like to say, require extraordinary proof, and none has been more extraordinary in recent years than Scottish embryologist Ian Wilmut's claim that he and his colleagues had cloned a sheep named Dolly from a mammary cell of a pregnant ewe. More than a year later, nobody has managed to reproduce the Dolly experiment, and Wilmut is under growing pressure to prove that his famous sheep is what he says she is. Last week at a genetics meeting at the University of Louisville, in Kentucky, he blandly conceded that there was a "remote possibility" that there could...
Seed has begun to remind pundits and editorial writers of Dr. Jack Kevorkian, who provokes strong feelings by shattering the taboo against physician-assisted suicide. The technical challenge involved in ending a human life is trivial, however. Cloning is another matter. Ian Wilmut, the embryologist who produced Dolly, the first clone of an adult mammal, says there are "serious safety issues" involved in cloning a human. In his experiments with animals, a quarter of his lambs died within a few days of birth. Ultimately, it took 277 attempts to produce Dolly. "Should we really consider or allow experiments of this...
This year's list of nominees was typically eclectic. Should we honor the Scottish embryologist Ian Wilmut and his immortal cloned sheep Dolly? What about Tiger Woods' thrilling 350-yd. drives into history? Or Alan Greenspan's steady-on-the-tiller stewardship of America's ongoing economic boom? Or--of course--the life and death of Diana, Princess of Wales...
...Best-Known Clone Embryologist Ian Wilmut made a big splash in the gene pool when he announced that he had cloned a sheep named Dolly. Though animals had been duplicated before, Dolly was the first ever created from an adult cell rather than an embryonic one, raising the specter that a human will one day follow in her hoofsteps...
