Daniel Cohen gives you all the history of cloning from plants to amphibians and mammals. One definition of the word cloning is a group of organisms descended from a single individual through asexual reproduction. Some plants actually clone themselvesand its considered natural.Some grapes used for wines today are clones of grapes from 2,000 years ago. Most produce at your grocery store are clones especially things like apples and peppers.Carrots were cloned in the 1950's but the experiment turned out to be so simple that it was done in some highschool labs. The cloning of frogs began in the 1930's but not til the 50's did the get a frog that lived a full healthy life. There were many horror novels in the 1970's about evil clones and clones that had predestined jobs. On July 5,1996 Ian Wilmut and Keith Campbells cloned sheep was born and the clone was a sucess. The sheeps name was Dolly. She was a female sheep or ewes and the first mammal to be cloned using an adult somatic cell. Wilmut, Campbell and other colleagues at the Roslin Institute in Edinburgh, Scotland used the nuclear transfer cloning process to create Dolly. Dolly died young at the age six, most of her type of sheep would live from twelve to fifteen years. If Dolly died yound because she was a clone was a big question on scientists minds. Dolly was autopsied and she did'nt die because she was a clone she died of Olvine Pulmanary Adenocarcinoma. It all made sense now because this was a common disease for Dollys type of sheep and this proved that the cloning was a complete sucess. Once Dolly died she was stuffed and kept as an artifact of history for the world to come.Was this review helpful? Yes NoThank you for your feedback.
