One American startup claims that he has managed to recreate a kind of prehistoric wolves from ancient DNA . You Terrible wolves have been extinct for 12,000 years but Colossal Bioscience said that Three copies were born in October and are being kept in a Nature Reserve of unknown location.
Romulus, Remo and Khaleesi puppies would be proof that it is possible to “revive” species from the modification of animal characteristics still existing on Earth. The Terrible Wolf (or Direct Wolf) became known for its apparitions in the eight seasons of the Game of Thrones fiction series.
Preserved in the piche
The genetic code was obtained from fragments of terrible wolves recovered from the wells of La Brea, a place of piche-areas where a thick form of crude oil emerges to the earth’s surface-in Los Angeles, United States.
These places are known to be valuable for archeology and paleontology, as they create natural traps that, over thousands of years, have trapped animals, plants and even human artifacts.
Piche acts as a natural preservative and preserves bones, feathers, skin, seeds, wood and other organic materials, preventing these pieces from setting out.
According to the company, in La Brea were found thousands of skeletons of outer wolves, however, because of the high temperature of gross oil, the DNA of the material was compromised.
In order to enjoy the pieces found, an international team of more than 50 scientists examined 46 remains of prehistoric wolves in search of viable DNA and was able to recover 0.1% of the genome.
Even if they are similar to current species, the terrible have a different genetic lineage that does not allow puppies with other canids – a family that encompasses dogs, wolves, chakal, coyotes and foxes – are viable.

Creation of puppies
Colossal Biosciences would then have been able to recover the material 500 times more than any team of researchers previously from a 13,000 -year -old tooth and a 72,000 -year -old skull and created the three puppies.
To, according to the company, ensure transparency with the return of the species, is sharing in its official channels the journey of Romulus, Remo and Khaleesi, since its genetic planning to its current time, five months.
The startup states that it will continue its efforts to restore lost species that have not had a genetically similar relative in millions of years, such as the Terrible Wolf.
Lobos-Terrible in the Media
In addition to being present in several seasons of the fictional series “Game of Thrones”, this species appears in other entertainment creations such as RPG game, “Dungeons & Dragons” and the video game game “Ark: Survival Evolved”.
In addition, the Terrible wolf appears in the song “Dire Wolf”, by the band Grateful Dead, released in 1970.
