1 . In the movie Jurassic Park (1993) a billionaire creates a theme park filled with dinosaurs, brought back from extinction through cloning by a team of scientists.

Although the film is of course fictional, the methods used in it to bring animals back from the dead may soon become reality.

Scientists from Harvard University in the US are currently working on resurrecting the woolly mammoth, a mammal that became extinct around 4,000 years ago.

However, it wouldn't be an exact copy of the hairy beast. "Our aim is to produce a hybrid elephant-mammoth embryo,” Professor George Church, head of the team of scientists, told The Guardian.

“Actually, it would be more like an elephant with a number of mammoth traits. We're not there yet, but it could happen in a couple of years."

The team is hoping to make a “mammophant”- a mix between an elephant and a mammoth. It would be like a regular elephant but have features from the mammoth that would make it more adaptable to cold weather.

Small ears, a thick layer of body fat and, of course, long hair are what helped the mammoth live in freezing temperatures.

So why go through all the effort and expense to bring back an animal that died out thousands of years ago? The answer lies in climate change.

It's hoped that the creatures will stop frost in the world's tundra from melting and releasing huge amounts of harmful greenhouse gases into the atmosphere.

Mammoths used to keep the tundra from thawing by punching through snow and allowing cold air to come in," said Church. In the summer, they knocked down trees and helped the grass grow."Church and his team are attempting to mix mammoth DNA, recovered from frozen samples of the animal found in Siberia, with that of the Asian elephant, which is its closest relative.

There are critics who believe that the media has got carried away with the story though, after several websites ran headlines such as Woolly mammoths will be roaming Earth again within two years.

“So far, scientists have managed to incorporate traits of the mammoth into elephant DNA. In a few years, they hope to make an embryo, but that's a long way from creating a viable embryo, "Popular Science magazine wrote.

Some have even gone so far as to call the story “fake news". Paleoanthropologist(古人类学家)John Hawks wrote on blog platform Medium: Is this just another case of the media sensationalizing(大肆渲染) what is otherwise a good science story?"

Although we may not be seeing woolly mammoths at the zoo any time in the near future, it's still exciting to know that there is still the possibility of a real Jurassic Park someday, however tiny that possibility may be.
