A biotech company’s own chief scientist has exposed their “de-extinction” claims as nothing more than genetic modifications of existing animals, revealing how corporate marketing can mislead Americans about scientific breakthroughs.
Story Highlights
- Colossal Biosciences marketed three wolf pups as “de-extinct” dire wolves, but their chief scientist later admitted they’re just “grey wolves with 20 edits”
- The company acknowledged it’s impossible to truly resurrect extinct species, contradicting their own marketing claims
- Scientists warn the complex genetic engineering carries potential unintended consequences that remain poorly understood
- Conservation experts dispute the authenticity of Colossal’s red wolf claims, calling them coyote-derived animals
Corporate Marketing Meets Scientific Reality
In April 2025, Colossal Biosciences announced the birth of three genetically modified wolf pups—Romulus, Remus, and Khaleesi—as the first “de-extinct” dire wolves. The company claimed to have analyzed ancient dire wolf genome samples from a 13,000-year-old tooth and 72,000-year-old ear bone, producing 45 engineered ova for surrogate mothers. This marketing presentation suggested genuine species resurrection through cutting-edge science.
However, just one month later in May 2025, chief scientist Beth Shapiro delivered a stunning clarification that contradicted the company’s previous statements. She acknowledged the animals are merely “grey wolves with 20 edits” and confirmed no ancient dire wolf DNA was actually spliced into the gray wolf genome. This admission represented a major departure from Colossal’s initial marketing narrative.
Scientific Methodology Under Scrutiny
Colossal isolated endothelial progenitor cells from gray wolf blood and rewrote 14 key genes in the cell nucleus to approximate dire wolf specifications. The company claims high cloning efficiency with this less invasive approach compared to tissue extraction methods. However, unaffiliated scientists emphasize genetic engineering remains “head-crackingly complex” with potential unintended downstream consequences when modifying cellular systems.
The fundamental distinction between true de-extinction and genetic modification matters significantly. True de-extinction would require recreating an organism genetically identical to the extinct species, while genetic engineering creates new organisms with selected traits from extinct species inserted into living species’ genomes. Shapiro’s admission that bringing back extinct organisms identical to original species is impossible undermines the entire de-extinction framework.
Questionable Conservation Claims
Beyond the dire wolf project, Colossal faces credibility challenges with other conservation efforts. Joseph Hinton from the Wolf Conservation Center disputed the company’s red wolf claims, stating they are merely “derived from coyotes captured in southwest Louisiana” rather than genuine red wolves. This suggests potential disputes over genetic lineage and authenticity that could affect conservation partnerships and regulatory approval.
‘They didn’t de-extinct anything’: can Colossal’s genetically engineered animals ever be the real thing?https://t.co/zFaB505aPN

The company’s broader timeline includes woolly mammoth embryos ready for implantation by late 2026, targeting a calf birth in 2028. However, no animals have yet been rewilded, meaning these projects represent early-stage proof-of-concept rather than field-ready conservation tools. The gap between marketing promises and practical conservation outcomes raises questions about resource allocation in genuine wildlife protection efforts.
