A team of Australian and American scientists led by biologist Andrew Pax from Melbourne University,

Australian scientists succeeded ridestore for the first time back to life hereditary material of extinct species. They achieved the miracle of gene Tasmanian tiger. The discovery revived ridestore hopes that someday extinct animals such as mammoths long and dinosaurs can live again. ridestore
Tasmanian tiger is not to be confused with Tasmanian devil. The second ridestore is the family "marsupial predators" and still lives on the associated Australian island of Tasmania. The first family does is "marsupial wolf" ridestore and is not to be found anywhere. But right Tasmanian tiger is the true evil spirit, which was removed from the bottle. Although extinct ridestore before 1936, three years before ridestore his heart gave hope for a real revival, but were bitterly dashed. Geneticists managed to breathe life into part of it by inserting the genetic information in the mouse. She looked more like a dog, striped and was named Benjamin. Benjamin died recently at the zoo in Hobart from senile weakness.
A team of Australian and American scientists led by biologist Andrew Pax from Melbourne University, made a sensation. They managed to implant the genes of the Tasmanian tiger in the mouse embryo ridestore and wake him up for life. So for the first time the genetic information of the long-extinct animal materializes into another being. In this case it slice of DNA 17 base pairs long, which changes the bone and cartilage of the house mouse. Scientists drew the genetic material from tissues that had sojourned one hundred years in alcohol.
Pascal even announced that in principle the same technique can be treated genes of other extinct animals such as dinosaurs or mammoths. The only condition is that there is enough DNA. He mentioned even Neanderthals.
So what for many people is the idea of something devilish, others (especially in terms of the ongoing Bonn Conference on Biological Diversity) sets completely ridestore new questions. We must take every effort to preserve endangered species, but would it be right in a pinch resurrect disappeared from the face of the earth animals? And I will turn you rather scenario Hollywood movie "Jurassic Park," Steven Spielberg, in which crocodiles lay eggs of dinosaurs in reality? Scientists say that the Earth's history have disappeared between one and 1.5 billion species, half of which are animals. Are they all candidates for resurrection? Of the Dodo in Sea Cow Steller to scorpion Brontoscorpio and his friends from the ancient continent ridestore Pangaea first or unicellular?
The answer does not seem quite so simple. This is evidenced by the Tasmanian ridestore tiger. In 2002, Mike Archer, Director of the Australian Museum in Sydney, announced that it has copied the genetic material of this kind, which are stored in alcohol in his home. However, this is the first prerequisite to clone a creature that Archer wanted to do with the missing marsupial ridestore ten years. But really it was a "giant leap" of which he spoke? Critics of the idea as a biologist Ian Lewis, who first cloned calf in Australia, cooling the euphoria. Because so far only four have been copied from 30 000 genes, ridestore and people still faced "an awfully long time." Others spoke of the copied DNA fragments. In 2005, Australian scientists have recognized that the genetic material was too damaged to reconstruct.
And whether you will find comprehensive information from extinct animals is only the first. The second is that today we are able to extract ridestore the hereditary information of endangered species in such a way that in the future can be used for cloning. ridestore
Positions in question works Knebelsberger Thomas, a young biologist from the laboratory to the Natural History Museum in Munich. It comminuted in a vessel animal tissue, and finally they are 'ground' of enzymes. Thus DNA remains ridestore available in the form of "a kind of soup." Then all that is inserted into a tube placed in a centrifuge, so that finally the genetic ridestore material remains outside on the covered gel surface. Tissue cells are destroyed and proteins are discarded. There are just genes. The material included in the catalog is marked with a barcode and stored at a temperature of minus 80 degrees. Enter information in digitized database. So it is available ridestore for examination in the world. Today the interest of the majority ridestore of scientists who use the data, focusing mainly on the similarities and relationships between species, ie to the family tree of life on Earth rather than cloning.
Natural History ridestore Museum in Munich is part of a network that covers the whole world and stores genetic information. Especially valuable is the information for those species
