Woolly Mammoths could one day walk the Earth again, it seems.
In a Jurassic Park-like experiment , using DNA from a frozen Mammoth specimen, Scientists were able to reproduce their blood.
And it's revealed that Mammoths used more that their shaggy coats to keep them warm, they had antifreeze in their blood.
Researcher Prof Kevin Campbell-of the University of Manitoba, Canada, said: "The molecules are no different than going back in time and taking a blood sample from a real mammoth."
To recreate the blood, scientists used DNA from a 43,000 year old specimen from Siberia.
It was used accompanying genetic information from their close relatives Asian Elephants.
And therefore showing that woolly mammoth's blood was adapted to freezing climates.
It's "antifreeze" blood carries oxygen around the body at freezing temperatures.
This trait is thought to have evolved after mammoth's relatives moved out of Africa.
But just by recreating a prehistoric protein doesn't mean that scientists can create a whole animal though.
DNA is not preserved in fossils. So this technique can't be used on animals that dies out millions of years ago.
The project began seven years ago when Prof Campbell contacted the Australian Centre for Ancient DNA at Adelaide University.
In the movie Jurassic Park DNA preserved in an insect trapped in amber millions of years ago is used to recreate dinosaurs. (Crazy!)
