Dr. Severino Antinori, an Italian embryologist, fires up the press in 2001 after announcing plans to clone the first human to help infertile couples have children. He claimed one of his patients was carrying a clone, but he failed to confirm his tale or produce the child. His comments launched a debate over the ethics of cloning human beings; countries like Britain and South Korea have since made it illegal to clone people, while the U.S. Congress has yet to ban the process.
