Founded in 2021 by entrepreneur Ben Lamm and renowned geneticist George Church, Colossal Biosciences is a biotechnology company at the forefront of de-extinction science.
Leveraging cutting-edge genetic engineering, the Dallas-based firm aims to resurrect extinct species, with projects ranging from the woolly mammoth to the Tasmanian tiger. Its work has sparked global interest, combining scientific innovation with environmental conservation.
Founders and Vision
Ben Lamm, a seasoned entrepreneur behind ventures like Hypergiant and Conversable, teamed up with George Church, a pioneer in synthetic biology from Harvard Medical School. Their shared vision extends beyond the boundaries of science fiction, aiming to restore ecosystems and mitigate biodiversity loss. Lamm’s expertise in scaling technology businesses complements Church’s deep understanding of genetics and bioengineering.
Reviving Extinct Species
Colossal’s flagship project involves reviving the woolly mammoth, a species that disappeared roughly 4,000 years ago. Using CRISPR-Cas9 gene-editing technology, scientists are modifying the genome of the Asian elephant, the mammoth’s closest living relative, to create a cold-adapted hybrid. The reintroduction of such hybrids to Arctic tundra regions could potentially slow permafrost melting by disrupting snow layers and promoting grassland growth.
In addition to the woolly mammoth, Colossal has announced efforts to resurrect the Tasmanian tiger (thylacine) and the dodo, broadening its portfolio of species aimed at bolstering biodiversity and restoring lost ecological functions.
Conservation and Ecosystem Restoration
While de-extinction grabs headlines, Colossal emphasises the broader impact of its work. Revived species are positioned as tools for ecosystem restoration, particularly in environments where their extinction has disrupted ecological balance. For example, reintroducing mammoth hybrids could combat climate change by preserving the permafrost, a natural carbon sink.
Furthermore, Colossal collaborates with conservation organisations to develop genetic solutions for endangered species, underscoring its commitment to preventing future extinctions.
Ethical and Scientific Challenges
The company has not shied away from addressing the ethical concerns surrounding de-extinction. Critics have raised questions about the ecological risks, welfare of engineered animals, and allocation of resources. In response, Colossal has assembled a diverse Scientific Advisory Board, comprising experts in genetics, bioethics, conservation, and environmental science, to guide its projects responsibly.
Additionally, Colossal has been transparent about the limitations of its work. The species it aims to revive will not be identical to their extinct counterparts but will carry traits that make them biologically and ecologically functional in their intended environments.
Funding and Partnerships
Colossal’s ambitious projects are underpinned by substantial financial backing. The company raised $15 million in seed funding and an additional $60 million in Series A funding from venture capital firms, philanthropists, and technology investors. These resources have enabled partnerships with academic and research institutions, accelerating the pace of scientific breakthroughs.
The Future of De-Extinction
Colossal’s work has broader implications beyond resurrecting extinct species. Its advances in gene-editing technology have potential applications in human medicine, agriculture, and climate resilience. By combining conservation biology with synthetic genomics, the company offers a glimpse into how biotechnology could reshape environmental management in the 21st century.
