The audacious dream of resurrecting the dodo bird, extinct for over 300 years, has taken a significant leap forward. Colossal Biosciences, a Dallas-based bioscience company, has announced a pivotal breakthrough in its de-extinction efforts, marking a major milestone in the ambitious project.
This breakthrough, achieved in September 2025, centers around the successful cultivation of primordial germ cells (PGCs) in pigeons, a crucial step as pigeons are the dodo’s closest living relatives. PGCs are precursor cells that develop into sperm and eggs, and manipulating them is essential for transferring dodo DNA into a living bird.
Decoding the Dodo: A Scientific Feat
Unlocking the Dodo’s Genetic Code
The initial phase of this ambitious project involved fully sequencing the dodo’s genome from ancient DNA extracted from a well-preserved specimen. This comprehensive genetic blueprint serves as the foundation for the entire de-extinction process.
Dr. Beth Shapiro, a renowned paleogeneticist and lead researcher on the project, emphasized the importance of this step. “Having the complete dodo genome is like having the instruction manual,” she stated. “It allows us to understand the unique characteristics of this bird and how to potentially recreate them.” This instruction manual is now being carefully studied and compared to the genomes of related bird species, particularly pigeons, to identify the key genetic differences that define the dodo.
Colossal Biosciences has secured $120 million in funding to support its de-extinction projects, including both the dodo and the woolly mammoth. This substantial investment underscores the growing interest and belief in the potential of de-extinction technology.
The Pigeon Connection: A Genetic Bridge
Given the dodo’s extinction, scientists are turning to its closest living relative, the Nicobar pigeon, as a surrogate species. The recent breakthrough in cultivating pigeon PGCs is critical for this approach. These cells are the precursors to sperm and egg cells, meaning they hold the key to passing on genetic information to future generations.
By manipulating these PGCs, scientists aim to insert dodo DNA into pigeon embryos, gradually transforming them into birds that more closely resemble the dodo. This process, while complex, represents a significant advancement in genetic engineering and opens up new possibilities for species revival.
The ability to edit the genes of the pigeon to express dodo traits is a complex undertaking. Scientists are focusing on key genes responsible for the dodo’s unique physical characteristics, such as its size, plumage, and beak shape. The goal is not to create an exact replica of the dodo, but rather a bird that shares many of its key traits and ecological functions.
Ethical Considerations and Conservation Implications
The Ethics of De-Extinction: A Moral Maze
The prospect of bringing back extinct species raises complex ethical questions. Some argue that de-extinction is a distraction from the more pressing need to conserve existing biodiversity. Resources spent on resurrecting extinct species could be used to protect endangered ones and their habitats.
Others argue that de-extinction could offer valuable benefits, such as restoring damaged ecosystems and increasing genetic diversity. The dodo, for example, played a role in seed dispersal on its native island of Mauritius. Reintroducing it could help restore the island’s unique ecosystem. It’s a debate with passionate arguments on both sides.

Conservation in the Age of De-Extinction
De-extinction efforts are not intended to replace traditional conservation methods. Instead, they are seen as a complementary approach that could offer new tools for addressing biodiversity loss. By studying the genomes of extinct species, scientists can gain insights into the genetic factors that make species vulnerable to extinction.
This knowledge can then be used to improve conservation strategies for existing species. For example, understanding the genetic basis of disease resistance in extinct species could help scientists develop strategies to protect endangered species from similar threats. The de-extinction project could therefore indirectly aid conservation efforts worldwide.
The success of the dodo de-extinction project could also raise awareness about the importance of biodiversity conservation. By showcasing the potential to reverse extinction, it could inspire greater public support for conservation efforts.
“De-extinction is not about playing God. It’s about using our scientific knowledge to correct some of the mistakes we’ve made and to ensure that future generations can experience the richness and diversity of life on Earth,” argues one proponent of the technology.
The Road Ahead: Challenges and Opportunities
Navigating the Scientific Hurdles
While the recent breakthrough is encouraging, significant scientific challenges remain. Transferring dodo DNA into pigeon embryos and successfully hatching a bird with dodo-like traits is a complex and uncertain process. There are also questions about whether a de-extinct dodo would be able to thrive in the modern environment.
The dodo evolved in a unique ecosystem on the island of Mauritius, where it faced few predators. The introduction of humans and invasive species led to its rapid extinction. Reintroducing a de-extinct dodo to Mauritius would require careful management of the island’s ecosystem to ensure its survival.
Another challenge is ensuring that the de-extinct dodo has sufficient genetic diversity to avoid inbreeding and other genetic problems. The initial population of de-extinct dodos would likely be small, which could limit their genetic diversity. Careful breeding programs would be needed to maintain a healthy population.
The Promise of Resurrection: A New Era for Conservation?
Despite these challenges, the dodo de-extinction project holds immense promise. If successful, it could pave the way for the resurrection of other extinct species, potentially restoring lost biodiversity and ecological functions. It could also revolutionize our understanding of genetics and evolution.
The de-extinction of the dodo could also have significant economic benefits. The reintroduction of the dodo to Mauritius could boost tourism and create new jobs. The island could become a major destination for ecotourism, attracting visitors from around the world who want to see the resurrected bird.
The success of the dodo project could also inspire new innovations in biotechnology and genetic engineering. The techniques developed for de-extinction could have applications in medicine, agriculture, and other fields. The project could therefore have far-reaching benefits beyond conservation.

FAQ: Frequently Asked Questions About Dodo De-Extinction
What exactly is de-extinction?
De-extinction is the process of bringing extinct species back to life, typically through advanced genetic engineering techniques. It involves using DNA from extinct animals to recreate them, often by inserting that DNA into the genome of a closely related living species.
How are scientists planning to bring back the dodo?
Scientists are using the dodo’s genome sequence and comparing it to the genomes of its closest living relatives, pigeons. They are then using CRISPR gene-editing technology to modify pigeon DNA to resemble dodo DNA. The modified cells are then implanted into a surrogate pigeon egg.
What are the potential benefits of de-extinction?
De-extinction could restore damaged ecosystems, increase biodiversity, and provide insights into genetics and evolution. It could also raise awareness about the importance of conservation and inspire new innovations in biotechnology. Some believe it could even correct past ecological damage caused by human activity.
What are the ethical concerns surrounding de-extinction?
Ethical concerns include the potential for de-extinction to distract from the need to conserve existing species, the welfare of de-extinct animals, and the potential for unintended ecological consequences. There are also questions about who would be responsible for managing and caring for de-extinct species.
How long will it take to bring back the dodo?
It is difficult to say exactly how long it will take, but scientists estimate that it could take several years or even decades. The process is complex and involves overcoming significant scientific and technical challenges. The recent breakthrough with pigeon PGCs represents a significant step forward, but much work remains to be done.
Where would the de-extinct dodos live?
The plan is to reintroduce the de-extinct dodos to their native island of Mauritius. However, the island’s ecosystem has changed significantly since the dodo went extinct, so careful management would be needed to ensure their survival. This includes controlling invasive species and restoring the dodo’s habitat. Learn more about the latest developments in the de-extinction project.
