To rebuild the 20 years ago primitive man complete gene

Information: neandertal man recovery plan

[] Message: according to foreign media reports, scientists from Germany recently said that they will be expected to rebuild its 20 years ago living in Europe of neandertal man's complete genome. Germany Leipzig Marx-Planck Institute for evolutionary anthropology of a study group this week in the United States National Academy of Sciences journal, Network Edition published their latest achievements. The research team by Jaswant-PA Bo. The researchers indicated that their latest research will be to rebuild the mammoth and cave bear genome bring hope.

Neandertal man is a primitive man, 20 years ago living in Europe. In about 3 years ago, neandertal man suddenly disappeared from the Earth. The neandertal man and modern man exists between the controversy has been associated for many years. Some researchers believe the neandertal man is being replaced by early modern people; there are also some researchers think, neandertal man and modern people may have a history of hybrid. PA Bo research group want to crack the neandertal man of DNA sequences, thus revealing the neandertal man and mystery of modern human relations.

Create a complete genome requires large amounts of DNA

Researchers said the neandertal man, cave bears and mammoths on process, the vast majority of recovery of DNA came from some microorganisms, these microorganisms in the neandertal man, cave bears and mammoths death alien to their organizations. But they are not only able to identify some of the original animal DNA, also unsure how they break down over time. In addition, they also came up with more than one way to avoid human DNA and the original human and animal DNA contamination. PA Bo and colleagues in the research report, wrote: "we believe that access to reliable neandertal man genome sequences completed technically feasible. ”

They said that by using different individual enough neandertal man DNA, you can overcome some DNA damage this problem so that you can identify whole genome sequences. University of Washington Professor Eric-terrinca Deus said: "the DNA contamination and degradation in the past decade has been the lead scientist of headaches. This study is the solution to this problem of serious attempts, we will of course have to welcoming attitude. "Terrinca UST not involved in the study of param Bo. He said: "I still cannot determine whether they have been completely solved the problem, but believe they face in that direction is an important step forward. ”

United States Institute of natural history at the Smithsonian National Museum of the ancient human biologist Richard-Spotts give PA Bo research group, will they work on is called "involves DNA degradation of important technology research". The same does not participate in the study of Spotts that researchers "for a long time to try to answer any questions related to the ancient DNA sequencing of the problem. ”

Michigan University anthropologist Milford-Volta Karpov said that create complete neandertal human genome is a great destination. But he said that this is just a sample of the "enhanced", but to do this you need a large amount of DNA, he is not clear whether the existing DNA. PA Bo research group's research funding comes from Marx-Planck Institute and the United States national institutes of health.
