The Mammoth Moonshot

A gene-edited mouse with a tiny winter coat is the first proof that a ten-billion-dollar plan to resurrect the woolly mammoth might actually work.

[Speaker 1]: It started with a mouse. [Speaker 2]: A very specific mouse. [Speaker 1]: Right. March 4, 2025. A lab releases a video of a mouse that looks... wrong. It has this thick, golden fur. The texture is completely different from a normal lab mouse. It looks almost like it’s wearing a tiny winter coat. [Speaker 2]: Which, genetically speaking, it is. That wasn’t a random mutation. Scientists had gone into that mouse’s DNA and edited seven specific genes to change its hair density and fat metabolism. They were trying to see if they could make a tropical animal survive in the cold. [Speaker 1]: But the goal isn’t to make winter-proof mice. [Speaker 2]: No. The mouse was just the proof of concept. The "Woolly Mouse," as they called it, was the first living, breathing evidence that a project valued at over ten billion dollars might actually work. [Speaker 1]: This is the project that everyone has heard the headlines about. The one that sounds like science fiction. The plan to bring the woolly mammoth back from extinction. [Speaker 2]: And that mouse is the seed. It raises the question we’re going to spend the next fifteen minutes answering. Is that little golden mouse a legitimate scientific breakthrough that changes how we handle extinction? Or is it just a very expensive mascot for a new kind of biological manufacturing? [Speaker 1]: Because by 2028, the company behind this says they’re going to have a mammoth calf. [Speaker 2]: And the path to get there involves zombie genes, artificial wombs, and a fundamental question about whether we are saving nature, or replacing it. [Speaker 1]: Come with us as we figure this out. [Speaker 2]: To understand how we got to a ten-billion-dollar mouse, you have to go back to 2019. [Speaker 1]: To a lab in Boston that was famous, but broke. [Speaker 2]: Well, relatively speaking. Dr. George Church is a legend at Harvard Medical School. He’s the kind of geneticist who looks the part-big white beard, talks about big ideas. And since about 2008, he had been talking about this idea that we could theoretically revive the mammoth. [Speaker 1]: But for a decade, it was basically a side project, right? [Speaker 2]: It was barely that. At one point he was running this research on about a hundred thousand dollars a year from Peter Thiel. In the world of high-stakes genetics, that is keeping the lights on. It was "life support" funding. [Speaker 1]: So what changed? [Speaker 2]: A cold call. Ben Lamm, a serial tech entrepreneur, reads about Church’s work in 2019. He flies to Boston, walks into the lab, and realizes the science is actually there. The bottleneck wasn't the biology; it was the capital. [Speaker 1]: Lamm is the one who treats this like a moonshot. [Speaker 2]: Exactly. He framed it like the Apollo program. You don’t go to the moon just to grab a rock. You go to the moon because building the rocket forces you to invent Teflon and GPS. He saw Colossal Biosciences-that’s the company they founded-as a way to build the "rocket" for biology. [Speaker 1]: Okay, but let’s stop for a second. Because when people hear "bring back the mammoth," they think *Jurassic Park*. They think we found a mosquito in amber, or in this case, a frozen mammoth in Siberia, and we’re just cloning it. [Speaker 2]: Right, and we need to be very clear: that is impossible. [Speaker 1]: Why? We have frozen mammoths. [Speaker 2]: We have frozen *parts* of mammoths. But…
