Human Cloning

The term cloning refers to the asexual production of a human or other animal whose genetic material is nearly identical to that of an existing life, such as an embryo, fetus, or adult. Most scientists distinguish between two types of cloning, reproductive cloning and therapeutic cloning. In reproductive cloning, a cloned embryo is created and implanted with the intent of bringing the clone to term and birthing a genetically identical individual. In therapeutic cloning, on the other hand, the goal is not to produce a cloned human or animal, but rather to create cloned embryos for research purposes, such as harvesting embryonic stem cells.

Back in 1997, the birth of Dolly, the famous cloned sheep, propelled cloning into the public spotlight and convinced many advocates that human cloning might finally be within reach, possibly even within the next few years. However, despite this success, numerous problems still exist with the cloning process that inhibit safe and successful cloning. SCNT continues to exhibit extremely low success rates, with multiple attempts resulting in only a few viable embryos. This thought alone makes cloning human beings a morally egregious endeavor. The inefficiency of the process requires much too high a price to pay, specifically the loss of multiple created human lives, for this to be an acceptable, even fathomable, activity.

Strictly from a scientific perspective, cloning is a dangerous and unpredictable practice. However, one cannot build an argument against cloning based solely upon the current state of technology because the state of science changes almost hourly. To make a final decision about human cloning, we must consider the ethical implications of this practice. In other words, if human cloning became a medically safe procedure, would there still be ethical reason to object to human cloning?
