What's happened
Colossal Biosciences has demonstrated 26 baby chickens hatched from a 3D-printed lattice mimicking an eggshell, using a novel silicone membrane that allows oxygen flow. The company says the technology could scale toward a moa-like bird, but independent scientists warn that the approach remains an artificial eggshell, not a full egg or moa resurrection. Experts emphasize the need for peer‑reviewed data and well-preserved moa DNA to assess feasibility.

writing style
- This section is written to be assertive and informative, with direct statements about what has been shown and what remains uncertain.
key implications
- The 3D-printed lattice and silicone membrane represent a concrete step in artificial eggshell technology, but they do not constitute a moa resurrection.
- Independent scientists highlight that crucial elements of an egg (nourishment structures and waste management) are missing in this setup, calling it an artificial eggshell rather than a full egg.
- Ethical and ecological questions persist about reviving extinct species and potential environments for any resulting animal.
what to watch
- Peer-reviewed publications detailing the methodology and results
- DNA feasibility studies linking moa genomes to modern birds
- Decisions on whether similar tech could assist conservation or lead to broader de-extinction efforts
How we got here
Colossal Biosciences has long pursued de-extinction goals, including woolly mammoths and dire wolves. The company’s latest claim centers on an artificial eggshell platform designed to enable incubation without a traditional eggshell. Moa eggs were enormous, and current avian surrogacy and genome methods face significant biological and ethical challenges in attempting to recreate the moa.
Our analysis
The Guardian (Hannah Devlin) reports on Colossal’s claim of hatching 26 chickens from an artificial eggshell and the scientific cautions from independent experts. The Independent corroborates details on the 3D-printed lattice and real-time embryo imaging, while noting skepticism from the scientific community. The AP Health and Science Desk adds context about the long road ahead and ethical concerns.
