Billionaire Ben Lamm, founder and CEO of Colossal Biosciences, is leading one of the most ambitious scientific projects of modern times: bringing the woolly mammoth back to life. The initiative is backed by renowned geneticist George Church from Harvard University, who has spent over a decade researching ways to recover the genetic traits of the extinct species. The project relies on CRISPR technology, an advanced genetic editing tool that allows scientists to insert mammoth genes into the DNA of the Asian elephant, its closest living relative. The goal is to create a hybrid species that can survive in environments similar to those once inhabited by ancient mammoths and potentially help restore Arctic ecosystems.
The funding for this initiative has reached a significant milestone, with Colossal Biosciences securing $200 million in a recent investment round. This has pushed the company’s valuation to over $10.2 billion, demonstrating strong investor interest in biotechnology and genetic engineering. The project’s timeline estimates that the first hybrid mammoth-elephants will be unveiled by 2028.
The idea of resurrecting extinct species sparks scientific and ethical debates, particularly regarding environmental impacts and animal welfare. Experts discuss whether the return of the woolly mammoth could aid in combating climate change by revitalizing Arctic grasslands, while others argue that the financial and scientific resources could be better allocated to the conservation of endangered species.
the advancement of genetic research and the role of colossal biosciences
Colossal Biosciences was founded in 2021 by Ben Lamm and George Church with the goal of developing de-extinction technologies, an emerging field in biotechnology. The company focuses on applying genetic editing techniques to recreate extinct species and potentially restore ecosystems. Since 2008, Church has been working on sequencing the woolly mammoth genome, identifying genes responsible for traits such as cold resistance, thick fur, and fat deposits.
To make the revival of the woolly mammoth possible, researchers use stem cells from Asian elephants, genetically modifying them to express mammoth-like traits. The method involves inserting dozens of specific genes into elephant embryos, which, if successful, could lead to the birth of a hybrid species that closely resembles a woolly mammoth.
The project’s development process involves multiple stages, including the creation of viable embryos, laboratory testing, and eventually implanting embryos into surrogate mothers, likely female Asian elephants. The scientific team estimates that the first specimen could be born by 2028.

scientific challenges and technological limitations
The initiative faces considerable technical challenges. Traditional cloning, such as the method used with Dolly the sheep, requires intact cells from the original animal, which do not exist for woolly mammoths. Fossilized remains found so far do not contain viable DNA suitable for direct cloning. Instead, the alternative method adopted is genetic editing, inserting mammoth genes into the Asian elephant genome.
Another major hurdle is the physiological adaptation of the hybrid to extreme environments. Woolly mammoths survived the Ice Age, enduring sub-zero temperatures and feeding on sparse vegetation. Scientists must ensure that the hybrid possesses the same resistance characteristics and behaviors as its ancestors. Developing viable stem cell cultivation techniques and creating genetically modified embryos are still evolving fields.
environmental implications and potential impact on the arctic tundra
The return of the woolly mammoth could have unexpected ecological consequences. The project suggests that introducing these animals to tundra areas could help regenerate ecosystems by transforming moss- and shrub-dominated landscapes into grasslands. This shift could slow the melting of permafrost, a frozen soil layer that stores large amounts of carbon.
However, some ecologists question whether this approach is feasible. The complexity of species interactions, the need for large populations to create a meaningful environmental impact, and the challenges of maintaining these animals in captivity all raise concerns. Additionally, there are uncertainties about how the hybrid would integrate into modern ecosystems and whether it could compete with native species for resources.
interesting facts about the woolly mammoth
- habitat: Inhabited cold regions of the Northern Hemisphere during the Pleistocene
- extinction: Disappeared approximately 4,000 years ago, possibly due to climate change and overhunting
- size: Could reach up to 13 feet in height and weigh around 6 tons
- diet: Herbivorous, feeding on leaves, bark, and tundra grasses
- closest living relative: The Asian elephant, sharing more than 99% of its DNA with the woolly mammoth

- 21st century: Advances in biotechnology open possibilities for species recreation through genetic engineering
- 2021: Colossal Biosciences is founded with the goal of “de-extincting” the woolly mammoth
ethical debates and future challenges
The woolly mammoth resurrection project raises ethical and philosophical questions about the limits of human intervention in nature. Some organizations argue that the financial and scientific resources dedicated to de-extinction could be better applied to protecting endangered species and restoring degraded natural habitats. Others highlight that the knowledge gained from the project could benefit medical research and drive new applications in biotechnology.
The creation of hybrid species also raises concerns about their welfare. Elephants have long reproductive cycles and strong social bonds, making the birth and adaptation of hybrids in captivity particularly challenging. Furthermore, reintegrating an extinct species into modern ecosystems requires long-term studies to prevent unforeseen impacts on biodiversity.
The development of Colossal Biosciences’ project will be closely monitored by the scientific community and the public. The promise of bringing back a species that disappeared thousands of years ago represents a milestone in biotechnology and could redefine the future of conservation. However, the scientific, environmental, and ethical challenges of the initiative remain open, making the coming years crucial for evaluating the feasibility of the proposal.
