The company that revived the dire wolf says a woolly mammoth calf could arrive by 2028, laying out a timeline for one of the most ambitious de-extinction efforts yet. According to NPR, the firm is editing the genes of Asian elephants to recreate mammoth traits.
Bringing back the woolly mammoth has long been the headline goal of de-extinction, a charismatic Ice Age giant whose return would capture the public imagination like no other. A concrete target date for a first calf turns that long-discussed ambition into a testable claim, even as it raises the biological stakes considerably.
Engineering a mammoth
The plan involves editing dozens of genes in the Asian elephant — the mammoth’s closest living relative — to introduce traits like cold tolerance, including extra fat layers and a shaggy coat. The company says it has already edited a portion of the roughly 85 target genes and aims to have embryos ready for implantation by the end of 2026, with a calf potentially born in 2028.
The effort focuses on a set of genes thought to confer the mammoth’s defining cold-adapted traits, from insulating fat to a thick coat. Having edited a share of those targets, the company frames the remaining work as achievable on a timeline that would see embryos ready within a year and a calf a couple of years later — an aggressive schedule for such complex biology.
Why the elephant is the starting point
Because Asian elephants share so much of their DNA with mammoths, the strategy is not to build a mammoth from scratch but to modify an elephant to express mammoth-like characteristics. That approach reflects both the power and the limits of current genetic tools: creating a cold-adapted, mammoth-like animal is conceivable, but doing it requires precise edits across many genes.
Starting from the mammoth’s closest living relative makes the task tractable, since most of the genome is already shared; the work is to introduce the specific differences that made a mammoth a mammoth. But editing many genes precisely, and then carrying an embryo to term in a surrogate elephant, involves formidable technical hurdles. The result, if achieved, would be a cold-adapted elephant hybrid rather than a genetically pure mammoth.
The bigger debate
The mammoth effort sits alongside the company’s other projects, including work on the dodo and the thylacine. Proponents argue such work could yield conservation benefits and restore ecological roles, while skeptics question the feasibility, cost and ethics of the endeavor. A 2028 target for a calf is a bold marker, and whether it holds will depend on solving the formidable biological challenges that stand between edited embryos and a living, healthy animal.
Supporters suggest a revived mammoth could help restore Arctic grassland ecosystems and that the underlying techniques could aid endangered species, while critics doubt both the feasibility and the wisdom of the project. The gap between edited embryos and a healthy calf carried to term is wide, and elephant reproduction is notoriously difficult. The 2028 target will test whether the ambition can survive contact with the biology.
