De-Extinction Dreams: $120 Million Fuels the Bid to Bring Back the Dodo
A Texas-based biotechnology company, Colossal Biosciences, is making headlines with significant progress in its ambitious project to resurrect the dodo bird, a species extinct for nearly 300 years. The company recently secured $120 million in funding to accelerate its “de-extinction” efforts, marking a pivotal moment in the burgeoning field of bringing back lost species.
The Science Behind the Revival
Colossal’s breakthrough centers on successfully cultivating primordial germ cells from pigeons – a close genetic relative of the dodo. These cells are the precursors to sperm and egg cells, a crucial step towards potentially recreating the dodo’s reproductive capabilities. Previously, cell culture techniques developed for chickens failed when applied to other avian species. A fresh formula specifically for pigeons has dramatically expanded reproductive technology for birds.
CEO Ben Lamm frames this achievement as a major milestone, likening it to a scene from the movie Up, and highlighting the potential for advancements in genetic engineering for extinct bird species. The ability to maintain avian reproductive cells long-term opens new avenues for species recovery.
Beyond the Dodo: A Portfolio of De-Extinction Projects
Even as the dodo is a flagship project, Colossal’s ambitions extend far beyond this iconic bird. The company is also targeting the resurrection of the woolly mammoth, the Tasmanian tiger (thylacine), the dire wolf, and the South Island giant moa. A collaboration with Lord of the Rings director Peter Jackson is underway to revive the moa of New Zealand.
In April 2025, Colossal claimed to have “revived” the dire wolf by combining ancient DNA with that of the modern gray wolf. They project the first woolly mammoth calf could be born as early as 2028. These projects are attracting significant investment, with figures like Chris Hemsworth, Nicholas Braun, and Paris Hilton among the company’s backers.
The Ethical and Ecological Debate
The prospect of de-extinction isn’t without controversy. Scientists and environmentalists are engaged in ongoing debates regarding the ethical implications, potential ecosystem impacts, and even the extremely definition of “bringing back” a species. Concerns center around the potential disruption of existing ecosystems and the welfare of reintroduced species.
Despite these concerns, Colossal argues that its investments in de-extinction technology are driving scientific discovery and developing tools beneficial for broader conservation efforts. The company views these projects as a way to address past ecological damage caused by human activity.
Future Trends in De-Extinction Technology
Advancements in Genetic Editing
CRISPR-Cas9 and other gene-editing technologies are becoming increasingly precise and efficient, making the manipulation of ancient DNA more feasible. This allows scientists to target specific genes responsible for traits lost during extinction, potentially recreating those characteristics in living relatives.
Artificial Wombs and Reproductive Technologies
The development of artificial wombs and advanced reproductive technologies, like the successful cultivation of primordial germ cells, are crucial for bringing de-extinct species to term. Overcoming the challenges of gestation and early development will be key to successful reintroduction.
Massive Data and Ancient DNA Analysis
Advances in DNA sequencing and bioinformatics are enabling scientists to extract and analyze ancient DNA with greater accuracy. This provides a more complete understanding of the genetic makeup of extinct species, informing de-extinction efforts.
The Role of Artificial Intelligence
AI and machine learning are being used to predict the effects of reintroducing extinct species into modern ecosystems. These tools can help scientists assess potential risks and develop mitigation strategies.
FAQ
Q: Is de-extinction really possible?
A: While significant challenges remain, recent advancements in genetic engineering and reproductive technologies suggest that bringing back certain extinct species is becoming increasingly feasible.
Q: What are the ethical concerns surrounding de-extinction?
A: Concerns include the potential disruption of ecosystems, the welfare of reintroduced species, and the allocation of resources away from existing conservation efforts.
Q: How long will it grab to witness a dodo bird again?
A: Colossal Biosciences has not provided a specific timeline, but the successful cultivation of primordial germ cells is a significant step towards that goal.
Q: What other species are being considered for de-extinction?
A: Besides the dodo, Colossal is focusing on the woolly mammoth, Tasmanian tiger, dire wolf, and South Island giant moa.
Did you know? The dodo bird became extinct less than 100 years after its discovery by Dutch sailors in 1598.
