Table of Contents
WASHINGTON — Colossal Biosciences,known for its enterprising efforts to revive the woolly mammoth,announced a significant breakthrough on tuesday. Scientists at the biotech company successfully edited seven genes in mice embryos, resulting in offspring with long, thick hair, affectionately nicknamed the “Colossal woolly mouse.” This achievement marks a crucial step in genetically engineering living animals to resemble extinct species, specifically as the company continues its work toward bringing back the woolly mammoth. The creation of the “Colossal woolly mouse” demonstrates the potential of advanced gene-editing techniques.
The Path to Mammoth Revival
Colossal Biosciences gained prominence in 2021 when it unveiled its ambitious plan to revive the woolly mammoth and, later, the dodo bird. The woolly mammoth, which roamed the frozen tundras of europe, Asia, and north America, went extinct approximately 4,000 years ago. Since then, the company has been dedicated to identifying key traits of extinct animals by studying ancient DNA.
According to CEO Ben lamm,the ultimate goal is to genetically “engineer them into living animals.” The creation of the “Colossal woolly mouse” represents a tangible step in this direction.Scientists at Colossal reviewed DNA databases of mouse genes to pinpoint genes related to hair texture and fat metabolism.
Colossal’s chief scientist, Beth Shapiro, explained that each of these genetic variations are “present already in some living mice,” but the team “put them all together in a single mouse.” The choice of hair texture and fat metabolism was deliberate,as these traits are believed to be closely linked to cold tolerance,a vital characteristic that enabled woolly mammoths to thrive in the prehistoric Arctic steppe.
CRISPR Technology and Gene editing
Technologies like CRISPR have considerably enhanced the ability to precisely edit genes.Vincent Lynch, a biologist at the University of Buffalo, who was not involved in the research, noted that scientists have been genetically engineering mice as the 1970s, but new technologies like CRISPR “make it a lot more efficient and easier.”
Colossal’s approach involved together editing seven genes in the mice embryos. While the results have been posted online, thay have not yet been published in a peer-reviewed journal or vetted by autonomous scientists. Still,Lynch acknowledged that the feat “is technologically pretty cool.”
future Plans and Ethical Considerations
Colossal’s initial focus on mice was strategic, serving as a proof-of-concept before potentially moving on to edit the embryos of Asian elephants, the closest living relatives to woolly mammoths. However, this next phase presents significant challenges. As Lamm explained, because Asian elephants are an endangered species, ther will be “a lot of processes and red tape” before any plan can move forward. Colossal has raised over $400 million in funding to support its ambitious projects.
The concept of “de-extinction” has also faced skepticism from self-reliant experts. Christopher Preston, a wildlife and habitat expert at the University of Montana, who was not involved in the research, argues:
“You’re not actually resurrecting anything — you’re not bringing back the ancient past.You’re changing an Asian elephant.”

Preston suggests that while it might be possible to alter the hair pattern of an Asian elephant or adapt it to the cold, it does not equate to bringing back a woolly mammoth.
Broader Implications and Potential Benefits
Despite the debates surrounding de-extinction, the refinement of precision gene-editing in animals holds potential benefits for conservation and animal agriculture. Bhanu Telugu, who studies animal biotechnology at the University of Missouri and was not involved in the new research, expressed his admiration for Colossal’s technological advancements, notably their ability to pinpoint which genes to target. Telugu said he was impressed by Colossal’s technology advances that enabled scientists to pinpoint which genes to target.
Furthermore, the technology developed by Colossal could have applications in human health. Lamm stated that the same approach might one day help fight diseases in people. The company has already spun off two health care companies as part of its business strategy. “It’s part of how we monetize our business,” said Lamm.
Conclusion
Colossal Biosciences’ creation of the “Colossal woolly mouse” represents a significant step in the field of genetic engineering and the ambitious pursuit of de-extinction. While the ethical and practical considerations surrounding the revival of extinct species remain a subject of debate,the technological advancements achieved by Colossal have the potential to impact various fields,from conservation to human health. The journey to bring back the woolly mammoth is far from over, but the “Colossal woolly mouse” serves as a tangible reminder of the possibilities that lie ahead.
