Human Cloning - the creation of human life from a single strand of DNA - was a radical discovery affecting every aspect of life. Although early efforts in the 20th century to achieve this goal were met with great controversy, scientists pressed forward. However, cloning had two large hurdles to clear: one medical and the other cultural. On the medical side, Human Cloning required more than just the creation of a healthy zygote, whose DNA matched the cloning target. The egg required a controlled environment for maturation: an artificial womb, as it would be impractical to use living females for this purpose on a larger scale. It was only after the creation of the artificial womb that the industry for cloning humans and human parts could really kick off. The biggest hurdle, however, was the moral and religious hysteria that surrounded the research. This hysteria was finally quelled due to the increased need for spare organs and limbs fuelled by wars of the late 21st century, and the strong backing of corporate interests into this research.
