Cloning man new friend or gods worst enemy Cloning can mean a couple of different things. In 1993, Dr. Jerry Hall and Dr. Robert Stillman, infertility researchers at George Washington University, successfully split a human zygote into two separate zygotes with the same genetic makeup, essentially the same process that occurs naturally with identical twins. They had created a clone, a second individual with the exact genetic blueprint of the first. Hall and Stillman didn't have the technology to allow their "twins" to survive full term. The birth of Dolly, though, changed all that. Dolly, the cloned lamb, was a very unique kind of twin. Her genetic double was an adult born years earlier. A team headed by Dr. Ian Wilmut, an embryologist at the Rosland Institute in Edinburgh, Scotland, evacuated the genetic material from the ovum of a sheep. When the nucleus from a cell of an adult sheep was electrically fused to the egg, it developed normally into a fetus, and eventually into a lamb. What is remarkable about Dolly is that this is the first time an animal has been cloned from an adult. It is also the first mammal that has no biological father. Dolly is a time-delayed twin. Virtually all of the confusion about the morality of cloning can be clarified once we answer two very basic questions, one factual and one ethical. First, what manner of being does cloning produce? Is it human? Would it have a soul? Second, what are our moral obligations to a clone? Can we use clones to create a race of slaves or as a living warehouse of human parts? Rejuvenation, suggests that it may someday be possible to reverse the aging process because of what we learn from cloning. Human cloning technology could be used to reverse heart attacks. Many scientists believe that they may be able to treat heart attack victims by cloning their healthy heart cells and injecting them into the areas of the heart that have been damaged. Heart disease is the number one killer in the United States and several other industrialized countries. Another reason why cloning is important Is because Its a breakthrough with human stem cells. Embryonic stem cells can be grown to produce organs or tissues to repair or replace damaged ones. Skin for burn victims, brain cells for the brain damaged, spinal cord cells for quadriplegics and paraplegics, hearts, lungs, livers, and kidneys could be produced. clone wars :: essays research papers Cloning man new friend or gods worst enemy Cloning can mean a couple of different things.
