Siberia with love … Lyuba, raising preserved in the ice of the tundra mammoth for 42,000 years, has traveled to London in a very special case. Since it was discovered in 2007 by a caregiver reindeer is displayed as an oddity from another time at the Museum Shemanovsky and never before had traveled to the West.
TheLyuba, the best preserved specimen of all the remains of mammoths that have emerged from the Siberian permafrost, has shot pass one of those races, a delight to the human species. When will the first cloned mammoth
Geneticist Ian Wilmut , father of la sheep Dolly , believes that science can be 50 years of the possibility of cloning extinct species like the mammoth. The method used would be the same as that used for live animals: retrieve the cell nucleus Mammoth frozen tissue, implant it into the egg of a female elephant (which previously would have extracted the core) and create an embryo with mammoth genes that would be implanted in the uterus of the pachyderm. The incubation period would be about 22 months.
However, Adrian Lister, a specialist in mammals proboscídeos Museum of Natural History, believes that is too early to speak of the resurrection of the mammoth : “The DNA found in Lyuba is highly fragmented and is not organized into cells. Thanks to him we were able to reach new and fascinating discoveries about Mammoths and how they adapt to their habitat, but I’m not one to rub their hands thinking that cloning is just around the corner. “mammoth skeleton exhibited in the London exhibition.

“Neither the technology we have today and the quality of remains give hope to clone a mammoth in a reasonable time, “warns Lister. “I do not
No wait for the resurrection of his kind, Lyuba, who died Siberian possibly drowned in the mud when he was little more than a month-old continues stunning tracks to the researchers, who found in your intestines and traces of milk residues grass , possibly chewed by his mother to the little shaggy breeding could digest.
” As the human species, mammoths originated in Africa and then spread to Europe, Eurasia and the New World “, says Adrian Lister. “One of the biggest mistakes is to believe that mammoths were the ancestors of elephants, when in fact it’s close cousins, who came to live at the same time and were adapted to other cold habitats.” “Climate change was undoubtedly the main reason for their extinction,” adds the researcher of the Museum of Natural History. “Rising temperatures 120,000 years ago almost ended their habitats: prairie that thrived were giving way to forests and tundra. They managed to recover in the Ice Age, but populations drastically decrease again until the final blow, some 6,000 years ago. ” “The definitive role of humans in their extinction remains to be seen, but the fact is that its disappearance coincides with the contact with human populations and the practice of hunting. It is quite possible that mammoths disappeared from the face of the Earth by the combined action of climate and man in a similar situation that the elephant lives today. “
