This new eugenics is simply the latest version of the age-old quest to make human beings--in fact, humanity as a whole--the way we want them to be: perfect.It includes our efforts to be rid of unwanted human beings through abortion and euthanasia.Tags: Turabian Term PapersWhat Makes A Person Powerful EssayEssay Questions On Flowers For AlgernonArgumentative Essay For FrankensteinCat Essay WriterExtended Essay Word Count
But human cloning represents one concrete step in that direction, and the forces pushing us from behind to take that step are tremendous.
These forces are energized, as we will see, by the very ways we look at life and justify our actions.
As for the potential clones themselves, Darnovsky is blunt:“Mostly, cloned animals are not quite right.
To try it in humans would be highly unethical,” she says.“Not quite right” is a nice way of putting it.
There are risks associated with egg retrieval, the process of harvesting eggs required for in vitro fertilization, is not without its own lingering ethical questions.
Risks also abound for surrogates, owing simply to the labors of bringing a fetus to term, and, of course, the act of childbirth.“This is really, I think, a breakthrough for biomedicine”He and his colleagues believe that genetically identical primates will allow for better research models for human brain diseases such as Alzheimer’s and Parkinson’s as well as subsequent therapies for them.Cloned monkeys could also make for a better animal model because of how much more similar they are to humans than other mammals.Rather, it entailed producing a nearly exact genetic replica of an already existing adult.The technique is called nuclear transfer or nuclear transplantation because it involves transferring the nucleus (and thus most of the genetic material) from a cell of an existing being to an egg cell in order to replace the egg cell's nucleus.SCNT has been used to clone a wide range of animals, including cats, dogs, horses, rats, and others.Although primates have been cloned before, most notably a rhesus macaque named Tetra born in 1999, ZZ and HH are the first primates cloned using SCNT.“We’re excited — extremely excited,” Mu-Ming Poo, Ph D, of the Chinese Academy of Sciences told NPR.In total, 63 surrogates were used, resulting in nearly 30 pregnancies and four births, of which ZZ and HH were the only ostensibly healthy offspring.Two other baby monkeys resulting from the procedure died within two days of their birth.“You couldn’t think about doing that kind of human experimentation,” said Darnovsky.The debate surrounding cloning is incredibly dense, owing to moral, ethical, even ontological reasoning.But, leaving the larger philosophical questions behind, there remain numerous health issues posed by human cloning for both the clones themselves and their surrogates.
