Overview

  • Colossal Biosciences has announced the birth of three genetically engineered wolf puppies—Romulus, Remus, and Khaleesi—designed to resemble the extinct dire wolf species.
  • The genetic engineering process involved 20 targeted mutations in the gray wolf genome to recreate traits like size, musculature, and coat color associated with dire wolves.
  • The puppies are currently housed in an 800-hectare controlled reserve, with no plans for reproduction or release into the wild at this time.
  • Scientists remain divided on whether these animals represent true de-extinction, with some describing them as hybrids rather than authentic resurrected species.
  • Colossal Biosciences aims to expand its de-extinction efforts to other iconic species like the mammoth, dodo, and Tasmanian tiger, raising ethical and ecological concerns.
