Throughout human existence, we have been the direct cause of many extinctions. Species, genera, families, orders and beyond are completely gone due to human expansion and interference. Science now provides us with a chance to help prevent more extinction as well as even bring back some species that have disappeared because of us. This new technology, cloning, has the potential to be a great asset of conservation, but it is very controversial. Cloning really came into the public eye when Dolly the sheep was cloned back in 1996, and its potential to preserve species near extinction has been debated ever since. Scientists are divided when it comes to the viability of cloning to help successfully. All of them know that it is possible, but there are some large obstacles when applied to the real world. The positives must heavily outweigh the negatives for such a costly procedure to be considered a feasible option for preservation. Science really needs to probe the workings of cloning before we can make a decision whether or not it will be able to preserve endangered species. Before we can investigate the pros and cons of cloning, we need to understand the process. The relatively easy to understand procedure starts out with an egg that has been removed from the surrogate mother’s uterus. A scientist first sucks out the egg’s nucleus using a syringe, leaving only the egg’s cytoplasm. The scientist then injects a whole cell under the egg’s outer layer using a different needle. An electrical pulse is then sent through the cell and egg, which fuse the two together. The cell begins to divide, and in a few days it will be large enough to implant back into the surrogate mother’s uterus. The surrogate

mother is treated with hormones prior to the implantation. If all goes well, in a few months the cloned baby will be born. This process is called Somatic Cell Nuclear Transfer, or SCNT. Conservationists often do not want the already endangered animals to be treated with hormones and studied in a lab, so the surrogate mother is often of a similar, common species. For example, an endangered guar would be birthed by the common cow. Advanced Cell Technologies (ACT) is a leading research team
