Overview

• Colossal Biosciences announced the birth of three genetically engineered wolf pups, Khaleesi, Romulus, and Remus, designed to exhibit traits of the extinct dire wolf species.
• The dire wolves were recreated by editing gray wolf DNA, reintroducing physical traits such as larger size and thicker manes, though some scientists argue they are not true dire wolves.
• George R.R. Martin, author of A Song of Ice and Fire, is an investor and cultural advisor on the project and expressed deep emotional connection upon meeting the wolves.
• The de-extinction effort has sparked ethical and ecological concerns, with comparisons to Jurassic Park highlighting potential risks of genetic manipulation.
• Colossal Biosciences plans to expand its de-extinction work to other species like the woolly mammoth, dodo bird, and Tasmanian tiger, while its technology has already contributed to conservation efforts for endangered species like the red wolf.
