 What concern was raised in recent years that is similar to cloning?
Bills are in the works in both houses of Congress to outlaw human cloning--a step urged on all governments by the pope himself. Cloning humans is taken to be either 1) a fundamentally evil thing that must be stopped or, at the very least, 2) a complex ethical issue that needs legislation and regulation. Besides, most researchers thought cloning humans was impossible--so, for the moment, there's unlikely to be a grant-request backlog. Less than two decades ago, a similar concern was raised over the ethical issues involved in "test-tube babies." The cloning procedure is similar to IVF. The only difference is that the DNA of sperm and egg would be replaced by DNA from an adult cell.
