Colossal Biosciences, a Texas-based biotech company, announced a breakthrough in growing pigeon primordial germ cells, a critical step toward the de-extinction of the dodo bird, which vanished nearly 300 years ago.

In a stunning scientific breakthrough, Colossal Biosciences, a Texas-based biotechnology company, announced on Wednesday that

researchers have successfully grown pigeon primordial germ cells (PGCs), a key precursor to sperm and eggs, marking a pivotal step toward the de-extinction of the dodo bird.

This development, which the company described as a “significant advancement” in avian reproductive technology, could eventually lead to the revival of the iconic flightless bird, which vanished from Mauritius in 1662 and has since become a global symbol of extinction.

The announcement has ignited excitement in the scientific community as well as among conservationists and the general public.

Colossal CEO and co-founder Ben Lamm emphasized the importance of the breakthrough, noting that their team’s ability to create culture conditions allowing pigeon PGCs to survive long-term represents a foundational step in dodo de-extinction efforts.

“This progress highlights how Colossal’s investment in de-extinction technology is driving discovery and developing tools for both our de-extinction and conservation efforts,” Lamm said in a press release.

According to Anna Keyte, the company’s Avian Species Director, previous attempts to adapt long-term germ cell culture techniques, originally developed for chickens, to other bird species had failed, even with close relatives like quail.

The company’s success with pigeons now provides a viable platform to pursue dodo reproduction.

The dodo bird, a flightless species native to Mauritius, disappeared in the 17th century as human activity and introduced predators decimated its population.

Over the centuries, the bird became an enduring symbol of human-caused extinction, and efforts to bring it back have long been a mix of scientific curiosity and cultural fascination.

Colossal’s breakthrough is the first time scientists have been able to replicate viable germ cell culture conditions for a species closely related to the dodo, giving hope that the legendary bird could once again roam the planet in some form.

Colossal Biosciences, which already counts high-profile investors such as actors Chris Hemsworth and Nicholas Braun, as well as influencer-activist Paris Hilton, has ambitious plans to raise an additional \$120 million to continue de-extinction projects,

not only for the dodo but also for other extinct species, including the woolly mammoth, the Tasmanian tiger, the dire wolf, and the South Island Giant Moa.

Earlier this year, the company claimed a breakthrough in reviving the dire wolf, combining ancient DNA extracted from a 13,000-year-old tooth and a 72,000-year-old skull with DNA from a modern gray wolf.

These experiments are part of a broader strategy to harness cutting-edge genetic technology to restore species lost to history.

Colossal’s focus on avian species revival also includes collaboration with prominent figures in entertainment. In July, the company announced a partnership with “Lord of the Rings” director Peter Jackson to revive the extinct Moa bird, native to New Zealand.

The project combines Jackson’s passion for wildlife conservation with Colossal’s pioneering biotechnology, highlighting the growing intersection between celebrity influence and scientific endeavor in high-profile conservation efforts.

Experts in genetics and conservation have praised the technical achievement while urging caution about the ecological and ethical implications of de-extinction.

Dr. Ellen Hartman, an evolutionary biologist at Stanford University, described the pigeon PGC breakthrough as “an extraordinary technical feat,” but emphasized that reintroducing extinct species raises complex questions.

“Even if we can recreate the dodo genetically, there are considerations regarding habitat, ecological impact, and the genetic health of these populations,” she said. “It is not just about creating the animal—it’s about ensuring it can survive sustainably in a modern ecosystem.”

The broader implications of Colossal’s work extend beyond bringing back iconic species.

The company believes that de-extinction technology can provide tools for conservation, allowing scientists to support endangered species by enhancing genetic diversity, improving reproductive success, and potentially reversing the decline of critically endangered animals.

By mastering germ cell culture techniques, researchers can preserve and manipulate genetic material in ways previously thought impossible, opening new avenues for biodiversity protection.

Colossal’s approach builds on decades of genetic research, including advancements in cloning, CRISPR gene editing, and synthetic biology.

The successful culture of pigeon PGCs represents the culmination of years of trial and error, and it reflects the broader ambition to push the limits of what science can achieve in restoring lost species.

If successful, the revival of the dodo could also serve as a template for future efforts to reintroduce other extinct birds, such as the passenger pigeon or the Great Auk.

Despite the excitement, the project faces significant scientific and logistical challenges. The dodo’s habitat in Mauritius has been altered dramatically since its extinction, and any reintroduction would require careful planning to prevent ecological imbalance.

Additionally, producing a viable, self-sustaining population will necessitate multiple generations, careful breeding programs, and continued advances in reproductive technology.

Colossal has acknowledged these hurdles but maintains optimism, citing ongoing success with closely related species as proof of concept.

The announcement has captured the imagination of the public, with social media buzzing with speculation and enthusiasm.

Memes, videos, and online commentary have celebrated the prospect of seeing a dodo bird in the 21st century, while others question the ethical boundaries of playing god with nature.

Colossal has responded by framing the work as both a scientific endeavor and a conservation mission, emphasizing that technology developed for de-extinction can also save species currently on the brink of extinction.

Looking ahead, the company aims to achieve several milestones over the next decade, including producing woolly mammoth calves by 2028, continuing to refine germ cell culture methods, and securing additional funding for long-term projects.

The dodo, as both a scientific challenge and a cultural icon, remains central to these efforts, symbolizing humanity’s capacity to correct some of the ecological mistakes of the past while advancing the frontiers of genetic science.

As the world watches, the story of the dodo bird’s potential resurrection stands as a remarkable intersection of technology, conservation, and ambition, illustrating the increasingly blurred line between what is extinct and what can be brought back to life.

Colossal Biosciences’ work represents not only a scientific milestone but also a cultural moment, reminding humanity of both the fragility of life and the power of innovation to redefine it.
