About the author Ian Wilmut: Breaking The Clone Barrier Ian Wilmut, a British embryologist and "father" of the cloned sheep Dolly, to receive Ernst Schering Prize 2002 with an endowment of 50,000 � In the closing years of this millennium, a quiet, unassuming British embryologist named Ian Wilmut set out to improve the productivity of farm animals and along the way set off a biological earthquake. The experiment he tenaciously pursued--to get a cell from an adult mammal to behave like a cell from a developing embryo--had long since been abandoned at the major centers of scientific research. Even high school biology students knew that once a mammalian cell had differentiated, and was programmed by nature to be bone or nerve or skin, it could not be deprogrammed. Yet Wilmut did it. After the birth of clone, there has been increasingly more debates about the morality of cloning. Now the author of the text argues that any attempt at cloning human beings is simply pointless, and he coins the phrase “Dolly’s false legacy.” It is an informal argument showing the writer’s viewpoints in the worldwide debate over the moral and medical implications of cloning. Here the author presents his view from aspects other than moral and medical ones. II.
