WHAT IT’S REALLY ABOUT
Inside Colossal: De-Extinction, Dire Wolves, And Rewriting Evolution’s Future
- Joe Rogan interviews Ben Lamm, CEO and co‑founder of Colossal Biosciences, a company focused on de‑extinction and species preservation using synthetic biology, AI, and advanced gene editing.
- Lamm explains how they reconstruct ancient genomes from degraded DNA, compare them to living relatives, and use tools like CRISPR to engineer animals with extinct traits—demonstrated by woolly mice, cloned red wolves, and newly created dire wolves.
- They discuss the ecological rationale for de‑extinction (e.g., mammoths in Arctic ecosystems, thylacines in Tasmania, toxin‑resistant marsupials in Australia) and the parallel development of tools like artificial wombs and plastic‑eating microbes.
- Throughout, they confront ethical, ecological, and geopolitical questions about “playing God,” regulatory lag, potential misuse by other nations, and how far humanity should go in redesigning life and even ourselves.
IDEAS WORTH REMEMBERING
5 ideasDe‑extinction is now technically feasible for some species using existing tools.
By assembling fragmented ancient DNA, aligning it with a close living relative, and editing key genes that control traits like hair, fat, size, and skull shape, Colossal can create living animals that are functionally equivalent to extinct species (e.g., dire wolf–like canids from gray wolf cells).
The same technologies used for “Jurassic Park–style” projects can directly aid conservation today.
Colossal is cloning critically endangered red wolves from blood samples, engineering marsupials to resist cane toad toxins, building population genomic maps for bison, and open‑sourcing tools so zoos and governments can clone or genetically rescue species without invasive tissue sampling.
Ecological impact modeling is central: the goal is functional de‑extinction, not just spectacle.
For mammoths, thylacines, and wolves, Colossal works with ecologists, indigenous groups, and governments to model how restored predators or megafauna would affect vegetation, prey species, disease dynamics, and landscape processes—aiming to replicate lost ecological roles rather than simply resurrect “cool animals.”
Ethical and philosophical debates hinge on the concept of “species” itself.
Lamm argues that speciation is a human construct with inconsistent definitions (genetic, reproductive, geographic, morphological), so insisting a gene‑edited mammoth or dire wolf “isn’t really one” is more philosophy than science—what matters ecologically is function, behavior, and phenotype.
Government processes and ideology are major bottlenecks compared to the science.
In one example, U.S. officials proposed spending 5–6 years and ~$22M to study whether wolf cloning was possible—even after Colossal had already produced cloned red wolves and offered to provide more animals and tech for free—illustrating how regulation and politics can lag far behind capability.
WORDS WORTH SAVING
5 quotesWe’re the world’s first de‑extinction and species preservation company.
— Ben Lamm
It’s not just a mammoth question, it’s a software and AI problem—assembling a shitty jigsaw puzzle where you don’t know what the box looks like.
— Ben Lamm
You guys made three dire wolves. That’s not moderately bold. That’s one of the craziest things a human has ever done.
— Joe Rogan
Speciation is a human construct—we’re trying to impose a rock definition on something that flows more like a river.
— Ben Lamm
Synthetic biology is like discovering fire. You can’t put the genie back in the bottle, and it will end up in nefarious hands too.
