Animal cloning is often a controversial topic; with its decade old history, successes with Dolly the sheep and advancements in science today. Unlike asexual species, cloning uses man-made tools and human engineering to replicate animals. As such, cloning has a long history of trial and error, often leading to tragic results and ensuing controversy. The advancements in science have escalated since the creation of Dolly, following Dolly’s cloning there are more methods that have been discovered, often varying based on the animal being cloned. These methods, have grown and can be traced as far back as the early 1950s. Now, Dolly the sheep was one of the first successful animal clonings, which will serve as the pinpoint from which to illustrate the processes of cloning animals.

Asexual species have the capability to reproduce without the use of fertilization, species that are asexual are able to replicate the genes found in that particular species and give birth to or separate into new offspring. However, cloning- in regards to mammals- is the process of removing the nuclei from an embryo and then transplanting an adult mammals cells in the nucleus, resulting in an animal with genetically identical information. In this view, asexual reproduction is a natural process for some species, whereas cloning is a man-organized and technology generated process. While cloning animals, many scientists have used embryonic cells, which come from the embryo of a baby animal. These cells are often grown in a laboratory in a mixture referred to as a “culture medium” (“FAQ, Embryonic Cells”), which provides the nutrients necessary for the cells to grow. Due to the fact that stem cells grow quickly the process of growing cells, similar to embryonic cells, is fast-paced and allows for the cloning process to be quick, as found with Dolly the
