After nearly a year of emotional argument in Congress but no new federal laws, the national debate over the future of human cloning has shifted to the states. Some states have already banned cloning in one form or another, and this year alone, 38 anti-cloning measures were introduced in 22 states.
The resulting patchwork of laws, people on all side of the issue say, complicates a nationwide picture already clouded by scientific and ethic questions over whether and how to restrict or to ban it altogether.
Since 1997, when scientist announced the birth of Dolly the Sheep, the first cloned animal, the specter of cloning babies, infants that are in essence genetic carbon copies of adults has loomed large in the public psyche and in the minds of lawmakers.
Today there is widespread agreement that cloning for reproduction is unsafe and should be banned. Now the debate has been shifted away from ethics of baby-making and toward the morality of cloning of embryos for their cells and tissues which might be used to treat diseases. The controversy pits religious conservatives and abortion opponents, who agreed embryos as nascent human life, against patients groups, scientists and the biotechnology industry.
