Some Good News! De-Extinct Dire Wolves
"In a scientific breakthrough that could forever change how humans interact with our planet, Colossal Biosciences said it has brought back an extinct animal that last walked the Earth roughly 10,000 years ago: the dire wolf." -ABC News
The U.S.-based biotech company has announced the successful birth of three genetically engineered dire wolf pups named Romulus, Remus, and Khaleesi. This achievement is considered the world's first successful de-extinction of an animal species.
The process involved reconstructing the dire wolf genome from ancient DNA found in a 13,000-year-old tooth and a 72,000-year-old skull. Scientists then modified the DNA of gray wolves, the closest living relatives of dire wolves, to include unique gene variants from the extinct species.
Colossal Biosciences is also working on de-extinction projects for other species, including the woolly mammoth, dodo, and Tasmanian tiger.
Reactions:
According to a couple of articles, some experts argue that these pups are not true dire wolves but rather genetically modified gray wolves. The morphological similarities among canids make it challenging to confirm the exact appearance of an extinct species like the dire wolf. While it represents a significant technological achievement, there are questions about the authenticity of the de-extinction and its implications for conservation and ethics.
TL;DR
The project has garnered attention due to its potential to revolutionize conservation efforts and our understanding of extinct species.
