U.N. diplomats, deadlocked for years over the drafting of treaty to ban the cloning of human beings worldwide, open negotiations on Monday on an alternative that would instead urge each government to adopt its own laws on human cloning.
At the heart of the debate are stem cell studies and other research that rely on so-called therapeutic cloning, in which human embryos are cloned to obtain the cells used in the studies and are later discarded.
Many governments, particularly those with large Catholic populations, have argued they view this type of research, for whatever purpose, as the taking of human life.
