Breeding human beings selectively to improve the genetic characteristics and for limiting the transmission of hereditary disease to future generations. While a great deal of research needs to be done to increase the effect of current methods of eugenics, there are four basic positive methods currently being used: artificial insemination; "sperm banks"; "heteronomous fertilization"; and arranged marriages. Cloning may be possible in the future. This, and implants, artificial organs, test-tube babies and other medical technology suggests, in addition to breeding, the manufacturing of humans. Preventive eugenic methods are also used: limiting marriages among those with similar genetic problems, limiting marriage among close relatives, and sterilization of people with undesirable characteristics.
The logical outcome of human history and development is for man to create clones of himself.
This is an extremely emotionally charged area, which can result in the loss of the ability to implement its practice.
