Dire wolves have been brought back from extinction. What does this mean?

Colossal Laboratories and Biosciences announced they have revived dire wolves from extinction.

Two genetically identical male "dire wolf" puppies named Romulus and Remus were born on Oct. 1 last year , with their sister Khaleesi following a few months later on Jan. 30 .

Created from edited grey wolf genomes, Colossal states that these three canines are proof that a "standardized toolkit for de-extinction" is possible.

Colossal 's dire wolves have been genetically modified to be more muscular and larger than grey wolves.

They're already over 80lbs ( 36kg ) at six months old , which is a comparable weight to a fully grown grey wolf .

The company's de-extinction efforts have drawn comparisons with the sci-fi film Jurassic Park .

However, there are important differences between the fictional film and the company's work.

Romulus, Remus , and Khalissi were initially cared for by their surrogate mothers, Colossal eventually separated them due to concern the dog parents weren't up to the task of caring for their large dire wolf pups.

The dire wolves are already displaying innate behavior similar to that seen in wild wolves or those raised in captive or semi-captive environments.
