First-Ever Revival of Extinct Animal by American Biotech
Colossal Biosciences, a U.S.-based biotechnology company, has announced a groundbreaking achievement in de-extinction by successfully reviving the dire wolf, a species that vanished over 10,000 years ago. Utilizing advanced gene-editing techniques, scientists at Colossal analyzed DNA extracted from ancient dire wolf fossils—a 13,000-year-old tooth and a 72,000-year-old skull—to identify key genetic traits.
They then introduced these traits into the DNA of modern gray wolves. Embryos carrying these genetic modifications were implanted into surrogate domestic dogs, leading to the birth of three pups named Romulus, Remus, and Khaleesi. These pups exhibit physical characteristics reminiscent of their ancient ancestors, such as white fur and distinct behavioral traits.
This achievement marks the first time an extinct animal has been brought back through biotechnological means after such a long period. While the revived pups share similarities with the original dire wolves, they are not genetically identical, as their genomes remain predominantly gray wolf. Nonetheless, this development opens new possibilities for conservation and the study of extinct species.
Colossal Biosciences continues to push the boundaries of genetic research, with ongoing projects aimed at reviving other extinct species, including the woolly mammoth, dodo, and Tasmanian tiger. These efforts not only aim to bring back lost species but also to enhance biodiversity and ecological understanding.
