human cloning
...d politics. According to a Human Cloning researcher, Phillip Kitcher, the ground for reproduction by cloning was initially broken with the discovery of test tube reproduction. This means that scientists were able to take an egg cell and a sperm cell and combine them outside of the body to fertilize and produce an embryo. Once scientists knew that fertilization outside the host was possible, they began to manipulate egg and sperm cells to see what changes could be made before, during, and after fertilization (137). In addition, after 277th tries of cloning a mammal using adult cells, in 1996 Ian Wilmut, a Scottish cell biologist, made history in the science field by announcing his finally success on cloning a sheep named Dolly from the mammary gland of a six year old ewe. Three years later on May 27th 1999, Wilmut and his coworkers found out that Dolly's telomeres, tiny strands of DNA that scientists believe hold the key to...
