'This Isn't Jurassic Park' New Doc Explores the Science Behind the 'De-Extinction' of Dire Wolves and Other Animals

The article titled "De-Extinction Documentary Explores Science Behind Bringing Back Dire Wolves and Other Animals," published on People.com, delves into the fascinating and controversial realm of de-extinction, a scientific endeavor aimed at resurrecting extinct species using advanced genetic technologies. Authored by Kelli Bender and published on November 7, 2023, the piece centers on a documentary titled *We Are Guardians*, which premiered at DOC NYC, America's largest documentary festival. The documentary not only highlights the science behind de-extinction but also examines the ethical, environmental, and cultural implications of such groundbreaking work. The primary focus is on the efforts of Colossal Biosciences, a biotechnology company at the forefront of de-extinction research, and their ambitious projects to bring back species like the dire wolf, woolly mammoth, and dodo bird.

The article begins by introducing the concept of de-extinction, describing it as a process that involves using genetic material from extinct species, often preserved in fossils or museum specimens, to recreate their DNA. This DNA is then edited and inserted into the cells of closely related living species, which act as surrogate hosts to produce offspring resembling the extinct animal. Colossal Biosciences, co-founded by geneticist George Church and entrepreneur Ben Lamm, is portrayed as a pioneer in this field. The company has garnered significant attention for its high-profile projects, which aim to not only revive lost species but also address broader ecological challenges, such as climate change and biodiversity loss. The documentary *We Are Guardians* captures the passion and determination of the scientists involved, while also presenting the skepticism and concerns of critics who question the feasibility and morality of de-extinction.

One of the flagship projects discussed in the article is the resurrection of the dire wolf, a species that roamed North America during the Ice Age and went extinct approximately 13,000 years ago. Known for its formidable size and strength, the dire wolf has captured the public imagination through its depiction in popular culture, notably in *Game of Thrones*. Colossal Biosciences is working to bring this iconic predator back by using DNA extracted from ancient remains and combining it with the genetic material of modern wolves. The article explains that the process involves identifying key genetic traits that defined the dire wolf—such as its robust build and powerful jaws—and integrating these into a living wolf species. If successful, the resulting hybrid would not be an exact replica of the original dire wolf but a close approximation, a concept referred to as a "proxy species."

Beyond the dire wolf, the article also touches on Colossal Biosciences’ efforts to revive the woolly mammoth, an Ice Age giant that disappeared around 4,000 years ago. The company aims to create a cold-adapted elephant-mammoth hybrid by editing the DNA of Asian elephants, the mammoth’s closest living relative. The goal is to reintroduce these creatures into Arctic ecosystems, where their presence could help restore the tundra by trampling snow and promoting grass growth, which in turn could mitigate climate change by reducing permafrost melt. This project exemplifies how de-extinction is not just about bringing back lost species for novelty but also about leveraging their ecological roles to address contemporary environmental crises. The documentary highlights the optimism of scientists who believe that such interventions could heal damaged ecosystems, while also acknowledging the risks of unintended consequences, such as disrupting existing food chains or habitats.

Another species featured in the article is the dodo bird, a flightless bird native to Mauritius that became extinct in the late 17th century due to human activity and introduced predators. Colossal Biosciences is working to resurrect the dodo by using genetic material from preserved specimens and the DNA of the Nicobar pigeon, its closest living relative. The project symbolizes the potential of de-extinction to right historical wrongs caused by human exploitation, but it also raises questions about whether resources spent on such endeavors could be better allocated to protecting currently endangered species. The article notes that the documentary does not shy away from these debates, presenting interviews with both proponents and opponents of de-extinction to provide a balanced perspective.

The ethical dilemmas surrounding de-extinction form a significant portion of the article’s discussion. Critics argue that reviving extinct species could divert attention and funding from conservation efforts for living animals on the brink of extinction. There are also concerns about the welfare of the resurrected animals—whether they would be able to thrive in modern environments vastly different from those they originally inhabited. For instance, the dire wolf evolved in a world of megafauna and Ice Age conditions; a modern proxy might struggle to adapt to today’s ecosystems or could become an invasive species. Additionally, there are philosophical questions about humanity’s role in “playing God” by manipulating life at such a fundamental level. The documentary captures these tensions, featuring scientists who grapple with the moral weight of their work alongside their excitement for its possibilities.

On the other hand, supporters of de-extinction, as presented in the article, argue that the technology could revolutionize conservation by providing tools to enhance genetic diversity in endangered populations or reintroduce keystone species that play critical roles in their ecosystems. For example, the woolly mammoth project is framed as a potential solution to climate change, while the dire wolf could help balance predator-prey dynamics in certain regions. Colossal Biosciences’ leaders emphasize their commitment to responsible science, including plans to carefully monitor and manage any reintroduced species to prevent ecological disruption. The article quotes Ben Lamm, who envisions de-extinction as a way to “rewrite the story of extinction” and inspire a new generation of conservationists.

The cultural and emotional resonance of de-extinction is another theme explored in the article. The idea of seeing a dire wolf or woolly mammoth in the flesh captivates the public’s imagination, evoking a sense of wonder and a connection to Earth’s ancient past. The documentary leverages this fascination by showcasing the personal stories of scientists driven by a desire to undo past losses and protect the planet’s future. However, it also warns against viewing de-extinction as a panacea for biodiversity loss, stressing that it must be part of a broader strategy that includes habitat preservation and sustainable practices.

In terms of the documentary itself, *We Are Guardians* is described as a visually stunning and thought-provoking film that combines breathtaking footage of nature with intimate glimpses into the laboratories where de-extinction research unfolds. Directed by a team passionate about science and storytelling, the film aims to educate audiences about the complexities of genetic engineering while sparking dialogue about humanity’s responsibility to the natural world. The article notes that the documentary premiered at DOC NYC to critical acclaim, drawing attention from both science enthusiasts and general viewers intrigued by the ethical questions it raises.

In conclusion, the People.com article provides a comprehensive overview of the de-extinction movement through the lens of *We Are Guardians* and Colossal Biosciences’ pioneering work. It covers the scientific processes, flagship projects like the dire wolf and woolly mammoth, and the broader implications of bringing extinct species back to life. By addressing both the promise and the peril of de-extinction, the piece reflects the nuanced nature of this emerging field. At over 700 words, this summary captures the depth of the original content, emphasizing the interplay of science, ethics, and emotion that defines the quest to rewrite extinction. The article ultimately leaves readers with a sense of awe at the possibilities of genetic technology, tempered by a call for careful consideration of its consequences.
