The Revival of the Woolly Mammoth: A Journey into Ethics and Science
Written on
Chapter 1: The Idea of Resurrection
When envisioning mythical creatures like dragons or unicorns, most of us can easily picture them without a description. However, the woolly mammoth, a real prehistoric animal, might soon be brought back to life. Recent advances in genetic research suggest that scientists could resurrect this remarkable creature by 2028.
The potential for reviving an extinct species is astounding, bringing us to a point where science fiction blurs with reality. Leading the charge in this endeavor is Colossal Biosciences, a pioneering company co-founded by geneticist George Church and entrepreneur Ben Lamm. Colossal's mission is to utilize cutting-edge CRISPR technology to modify DNA and bring back the woolly mammoth, aiming not only to restore an extinct species but to address pressing ecological issues.
"Colossal creates innovative technologies for species restoration, critically endangered species protection and the repopulation of critical ecosystems that support the continuation of life on Earth." - Colossal Biosciences
This aspiration to revive woolly mammoths is reminiscent of a real-life Jurassic Park scenario. In their article for Newsweek, Lamm and Eriona Hysolli, the Head of Biological Sciences at Colossal, detail their ambitious goals:
Section 1.1: The Science Behind the Resurrection
"We're not just making single nucleotide edits; we're able to do multiplex gene editing of lots of parts of the genome simultaneously," they explain. This approach accelerates their timeline for producing the first new woolly mammoths, which they project to achieve by 2028.
To understand the urgency behind their work, consider the looming threat of climate change and the alarming prediction that Earth could lose half of its biodiversity by 2050. Colossal aims to reintroduce extinct species like the woolly mammoth to restore ecological balance.

Section 1.2: Why Woolly Mammoths?
Woolly mammoths were not contemporaries of dinosaurs; they roamed the Earth until about 4,000 years ago, overlapping with the construction of the Great Pyramids. Lamm and Hysolli highlight two main motivations for their resurrection project:
- The urgent need for new tools in elephant conservation, particularly concerning reproductive biology.
- The desire to combat human-elephant conflict, which is a major cause of elephant mortality.
The team believes that by understanding mammoth genetics, they can develop strategies to protect existing elephant populations.
Chapter 2: The Genetic Journey
To achieve their ambitious goals, Colossal scientists are working with Asian elephant cells, transforming them into stem cells capable of developing into various types of cells. Despite a limited supply of elephant cells due to dwindling populations, the researchers are building a vast collection of elephant genomes.
The breakthrough came on March 12, 2024, when they successfully created the first Asian elephant iPSCs in a lab by blocking an anti-cancer gene. This advancement allows them to replicate these cells indefinitely, providing a sustainable resource for their research.

Long Term Goals
With a reliable source of elephant iPSCs, researchers plan to edit the DNA to incorporate traits suited for survival in cold climates. The ultimate goal is to produce a new species resembling the woolly mammoth, with the first expected birth set for 2028.
Ethical Considerations
As exciting as these developments are, they raise significant ethical questions. Heather Browning, an animal welfare philosopher, emphasizes that these new mammoths won't have the guidance of elder mammals to learn survival skills. The challenge is to ensure these creatures can adapt to their environment without prior knowledge.
Lamm and Hysolli address these concerns, stating their commitment to transparency and ethical practices throughout their research. They emphasize that their work is not merely about reviving a species but about using their findings for broader conservation efforts.
Perspective Shift
Living in a time when the revival of woolly mammoths seems possible is a remarkable feat of human ingenuity. While we may not have flying cars, the prospect of seeing these creatures roam the Arctic again is on the horizon, with the first births potentially happening within this decade.
