The Cloning Debate

The first attempt in cloning was conducted in 1952 on a group of frogs.

The experiment was a partial success. The frog cells were cloned into other

living frogs however, only one in every thousand developed normally , all of

which were sterile. The rest of the frogs that survived grew to abnormally large

sizes. In 1993, scientist and director of the in vitro lab at George

Washington University, Jerry Hall and associate Robert Stillman, reported the

first ever successful cloning of human embryos. It was the discovery of in-

vitro fertilization in the 1940’s that began the pursuit to ease the suffering

of infertile couples. After years of research, scientists learned that

The cells are coated with a

protective covering "called a zona pellucida, that is essential to development"

(Elmer-Dewitt 38), which was stripped away and replaced with a gel-like

substance made from seaweed that Hall had been experimenting with. The

scientists were able to produce forty-eight clones, all of which died within six

days. Other scientist have been quoted saying that although the experiment is

fairly uncomplicated, it had not been tested before because of the moral and

ethical issues surrounding an experiment such as this one. Some people believe

that aiding infertile couples is the only true benefit to cloning human embryos,

and fear that if the research is continued it could get out of hand. Other

advantages that have been suggested include freezing human embryos for later use,

in the event that a child should get sick or die. If a parent has had their

child’s embryos cloned and frozen and their child dies at an early age of crib

death, the parents could have one of the frozen embryos de-thawed and implanted

into the womb. Nine months later, the mother would give birth to a child that

was identical to the one they had lost. Or if a four year old child develops
