Scientists are said to be just two years away from bringing the woolly mammoth back from extinction.
The giant prehistoric creatures could roam the Earth for the first time in 4,500 years after researchers successfully merged genes from the long dead mammals with that of elephants.
So far, they have successfully switched 45 sections of DNA since the project began in 2015.
And Harvard scientists claim they are now within two years of creating a hybrid embryo that will have all the characteristics of the shaggy beasts.
It would have genes for mammoth features such as long hair, thick layers of fat, and cold-resistant blood.
