Technology channels () message: where we come from, who we are, where we will come to? these three issues are on your own questions, and is also the ultimate discuss philosophers. Scientists will also be discussed, not with words, but with the experiment and data.
Germany's Max Planck Institute for evolutionary anthropology, Leipzig, recently announced that the United States a tech companies to restructure an extinct 3 years of prehistoric human-neandertal human gene sequences, trying to fill a human evolutionary course several blank snippets.
Gene found set is difficult to find time
According to reports, the genes needed to maintain continuously patching, the end of the gene that life over time. Therefore paleontology genes remains laboratory technical bottlenecks and, above all, long-term hydrolysis and oxidation process can damage DNA, to sample more than 100,000 years, gene almost could not be saved. Followed by modern genetic pollution, because of the ancient gene too, as long as some modern gene doping will make research results produced.
Study on the initial selection of fossils as Croatia unearthed a belongs to 45,000 years ago neandertal man's bones, the legacy of gene above should only 100 pieces. Therefore, the research required use of 454 Life Sciences new development of Genomic sequencing technology 454 low cost Machine, and the effective reorganization of fragmented small fragments.
Neandertal man has mixed with modern humans, they have language skills, the structure of the brain, skin, as well as issues such as population density has been plagued by the scientific community for more than a century. To be successful reorganization of neandertal man's genes, even if only some of them, on mystery fragments of human prehistoric life form and evolutionary history has a great help.
Now a study of recombinant DNA is still in its early stages, but has met with many difficult challenges, one of the most troublesome are looking set of genes. Researchers said that most of the neandertal man's fossils are not included in the neandertal man's genes, but they were covered by contact with these bones of researcher's genes. Fortunately, the research program director of Shi Wen Bo Po raised. PhD (Dr. Svante Paabo) developed a new technology has the potential to bring modern contaminated gene isolation.
