British Researchers Say Genetic Engineering May Allow The Extinction Of Biologic
Genes with ancient map of “recycling” them possible. Ever since scientists announced in November last year, almost all the genes crack the Mammoth, the ability to “recycling” Mammoth raises a lot of speculation.
Today, the United Kingdom, “New Scientist” magazine lists the 10 most likely by gene technology “rebirth” of organisms, including 25 000 years ago, Neanderthal extinction.
Genes “born again” “New Scientist” 7 reported that the complete genome is “recycling” the key to biological extinction. However, the biological event of a death, because of their genes sunlight, bacteria and other damage, not complete.
However, there are exceptions. If those bodies were extinct creatures frozen, on hold in a dark cave or dry environment, gene fragments may be intact, as scientists discovered 60,000 years ago, the Siberian mammoth remains.
Molecular biologist at Pennsylvania State University, Stefan? Schuster, said gene even if the ideal storage conditions, but also “support” not 100 years. “The real worth of the (gene) within the sample the best in 10 years.”
Whether to genetic map “recycling” of ancient living organisms, Schuster believes that existing technology does not meet this condition, but one day can make the attempt.
British “Daily Telegraph” said, scientists recently announced that they have been extinct Tasmanian tiger gene into mice in which genes were “born again.” This is the first time scientists have achieved such success.
10 biological “New Scientist” to explain its list of 10 possible “rebirth” of the bio says, so for example not only to consider the feasibility of the operation, as well as the biological “charismatic.”
One of them is Neanderthal. Germany’s Max? Planck Institute for Evolutionary Anthropology public people expected the draft sequence. If the Neanderthal “embryonic” create a successful, modern man will become the ideal “surrogate mother.”
Followed by 11,000 years ago extinct short-faced bear. This bio-size large, vertical height to one-third higher than the polar bear, weighing 1 ton.
Expected to “resurrection” is the latest generation of biological Tasmanian tiger. As the last one Tasmanian tiger died in 1936, its organization has been well protected, to achieve high-quality help scientists map genes mapping. And has a “Tasmanian devil,” said the Tasmanian devil will be good “surrogate mother.”
In addition, there are promising species Glyptodon, saber-toothed tiger, dodo, hairy rhinoceros, giant ground sloth, the Irish elk and moa.
Difficulty in For this vision can be achieved, whether there are other problems, experts have raised doubts.
German Max? Planck Institute for Evolutionary Anthropology expert Svante? Pepper said: “difficult to say what is absolutely impossible, but this requires far more than the existing technological level. I can not imagine how (this goal). ”
Apart from the development of gene technology, scientists have to their “recycling” in the matrix to find the right embryos for embryonic development.
Even the “New Scientist” for the extinction of biological “born again” bright future “exciting”, but also not forget to mention: “to bring these extinct creatures in real life will lead to many practical problems, such as Where they live … … ”
