Recently a British newspaper announced that scientists
in Edinburgh had succeeded in making the world's first clone of an adult animal.
The clone, a 7-month-old sheep, was called "Dolly"
after Dolly Parton, the American country singer. A
cell was taken from a sheep, then implanted in a surrogate mother. The
scientists say that cloning will enable us to study diseases and produce more
health care products. In theory, the same technique
could be used to clone human beings, but British scientists said that no responsible
person would do such a thing and that such experiments would be outlawed by British
law. Dolly is identical to her "mother"
and has been photographed more than any other sheep in history. However,
many people are afraid that cloning could be used for other reasons. For
example, some people have suggested that cloning could be used to create private
armies or thousands of slaves to work in factories. |
