Contrary to popular belief, cloning has been in existence prior to God’s creation of man. It all began thousands of years ago with many organisms of nature through a process known as asexual reproduction. However, by the late 20th century, scientists developed a method to manipulate an organism’s deoxyribonucleic acid (DNA), known as genetic engineering. This development led to the birth of animal clones and many ethical issues to follow.
Cloning is defined as “a form of genetic engineering in which the DNA of a person, animal, plant, or even bacterium is used to produce a perfect or near-perfect genetic replica of the original” (Stanley, 2000a, p. 7). As stated earlier in the text, the history of cloning dates back many years ago. According to Encarta On-line Encyclopedia (2003), organisms—such as bacteria—reproduced asexually through a process known as fission. Various forms of yeasts would reproduce via bumps that would grow on the parent cell. These bumps would eventually receive a copy of the parent’s DNA and separate from the parent as a clone. Additionally, fruit-bearing plants—such as strawberries and various forms of grasses—would replicate themselves through their own stems that grew above ground. Man began to clone plants by taking “a cutting from one plant and placing it in a medium, such as earth or water, in
