Resurrect An Extinct Animal

Brought to life an extinct animal currently now not only a dream. Brought back an animal back to life like in the Jurassic Park movie, almost become a reality.

On Tuesday, May 20,2008, a group of scientist said "have resurrect" a gene from a Tasmanian tiger that was extinct.

The method precisely like in Jurassic Park. The scientist from several universities in Australia and United States extract a gene from a thylacine specimen, an animal that was similar like a dog that more was known by a name of the Tasmanian tiger. Then they resurrect this gene in a mouse embryo.

"This is the first time DNA from an extinct species was use to provoke the functional response to other living creatures," said Andrew Pask from University of Melbourne that led the project.

The last Tasmanian tiger finally died in his pen in Hobart Zoo in 1936. However, the thylacine tissue, both the young and the mature tissue, preserve in alcohol. The research team use this specimen from the Victorian Museum in Melbourne.

"The research team isolate DNA from a 100 years old specimen. After make sure that is really a thylacine DNA, then we plant it in a mouse embryo and research its function. Evidently, this thylacine DNA really could be awaken. Its function in a mouse cartilage development, that later will form bones", explained Pask.

The findings appeared to generate a dream to recreate an extinct animal. Mike Archer, a lecturer in University of New South Wales that led efforts to clone thylacine when still became the director of the Australian Museum, acknowledge these findings as a very important step.

"Personally, I really sure that could happen. I also had a team that research an extinct animal. We thought that possibly could carry out", he said to the Australian Broadcasting Corporation.

Pask also sure that create an extinct animals possibly will be carry out one day later. However, according to him, that was not possible to be done with his team techniques at this time.

"We could indeed see a function of the genes in this animal. But, most animals had 30,000 genes", he said.

With more advance techniques, continued Pask, the researcher could possibly bring an animal that has been extinct back to life.

Nowadays where increasingly a number of species that was threaten to extinct, the findings was considered very vital.

"Our method showed that our access towards the genetic diversity of living creatures that were extinct possibly not fully destroyed," said Marilyn Renfree from University of Melbourne.

However, Renfree also warned that the aim of the research not to recreate animals that were extinct.

"That can be possibly carried out sometime in the future. But, I thought not in our generation. In our children generation, maybe. But, still was thus needed many stages before we could really carry it out.

A dream to brought back an extinct animal appeared to explode in 1993 when Jurassic Park attacked the cinema. In a film by Steven Spielberg based on a novel by Michael Crichton, was depicted by a scientists clone a dinosaur gene that was obtain from a fossil of prehistoric mosquitoes that had sucked blood of the giants animal. The prehistoric giant then was reborn and spread terror.
