Scientists say they have resurrected the dire wolf

CNN - Apr 7th, 2025

Colossal Biosciences, a Dallas-based biotech company, has announced the successful de-extinction of the dire wolf, a species that died out approximately 12,500 years ago. The company utilized ancient DNA, cloning, and gene-editing technology to create three dire wolf pups from gray wolves, the closest living relatives of the prehistoric predator. This achievement marks the first successful de-extinction of an animal and is seen as a significant milestone for Colossal, which has been working on resurrecting other extinct species like the mammoth and the dodo since 2021. The dire wolf pups are being housed at a secured, undisclosed location, and the company is continuing its efforts to use these technologies to aid endangered species.

The implications of this scientific breakthrough are considerable, raising questions about the role of de-extinct species in modern ecosystems. While Colossal sees potential in using these technologies to benefit endangered animals, critics argue that the resources could be better allocated and express concerns over the welfare of surrogate animals used in the process. Despite these concerns, Colossal has taken steps to ensure animal welfare, and experts like Christopher Preston acknowledge their efforts. However, the practical ecological role of resurrected species like the dire wolves remains uncertain, particularly in regions where existing wolf populations face political and environmental challenges.

Fair Story

Consider it well-founded

The article provides an intriguing look at the groundbreaking scientific achievement of resurrecting dire wolves through genetic engineering. It effectively captures public interest by connecting the story to popular culture and current scientific debates. However, the article's accuracy is somewhat limited by a lack of independent verification and detailed explanation of the gene-editing process. While it presents the perspective of Colossal Biosciences and its representatives, it could benefit from a more balanced presentation by including a wider range of viewpoints. The story is timely and relevant, addressing significant ethical and ecological questions. Its readability and engagement are strong, but the potential for controversy and debate could be enhanced by exploring opposing perspectives and the broader implications of de-extinction technology.

Accuracy

The article presents a groundbreaking claim that dire wolves have been resurrected using genetic technology, which is a significant scientific development. However, the story's accuracy hinges on the verifiability of several claims, such as the use of ancient DNA to reconstruct dire wolf genomes and the specific genetic modifications made. The article states that Colossal Biosciences used DNA from ancient fossils to create a hybrid genome, but it lacks detailed evidence or third-party verification of these scientific processes. Additionally, it mentions the use of domestic dogs as surrogates, a claim that requires further confirmation. While the article references statements from experts like Love Dalén, it does not provide independent verification of the claims made by Colossal Biosciences, which could affect the story's overall accuracy.

Balance

The story predominantly presents the perspective of Colossal Biosciences and its representatives, such as Ben Lamm and Love Dalén, who are directly involved in the project. While it briefly mentions criticisms from some quarters regarding the ethical and ecological implications of de-extinction, these viewpoints are not explored in depth. The article could benefit from a more balanced presentation by including more perspectives from independent scientists or ethicists who might have differing views on the potential consequences of de-extinction. This would provide readers with a more comprehensive understanding of the topic and the various opinions surrounding it.

Clarity

The article is generally well-written and easy to understand, with a clear structure that guides the reader through the key points of the story. It effectively uses layman's terms to explain complex scientific concepts, such as gene editing and de-extinction, making the information accessible to a general audience. However, the article could improve clarity by providing more context or background information on the ethical debates surrounding de-extinction, which would help readers grasp the broader implications of the scientific developments discussed.

Source quality

The article relies heavily on statements from Colossal Biosciences and its co-founder, Ben Lamm, as well as an expert, Love Dalén, who is an adviser to the company. While these sources are authoritative regarding the company's activities, the lack of independent sources or third-party verification limits the overall reliability of the information presented. The article would benefit from additional input from external experts or scientists not affiliated with Colossal Biosciences to provide a more balanced and credible perspective on the claims made.

Transparency

The article provides some transparency by explaining the basic methodology used in the de-extinction process, such as the use of CRISPR technology and ancient DNA. However, it lacks detailed information on the specific gene-editing techniques and the criteria for selecting the genetic traits to be modified. Furthermore, the article does not disclose potential conflicts of interest, such as the financial interests of Colossal Biosciences or the involvement of its advisers. Greater transparency in these areas would enhance the article's credibility and help readers better understand the basis of the claims.
