Colossal Biosciences’ October 14, 2026 announcement centered on GenoMorph, an AI platform intended to identify genetic targets for recreating some dodo-like traits. The company reported about 2,300 candidate DNA elements related to beak shape, alongside progress in genome assembly and bird reproductive-cell research. These are steps toward an engineered dodo-like bird—not evidence that an extinct dodo has been brought back.

How GenoMorph works with scarce dodo DNA
Colossal says it is working with one dodo genome, compared with about 100 genomes available for its mammoth work. The limited dodo reference makes it harder to identify which DNA differences may underlie the bird’s distinctive anatomy.

Rather than relying on dodo DNA alone, GenoMorph combines comparative genomics with developmental biology and 3D morphology. The analysis draws on more than 70 living bird species and uses skull measurements and embryo-development data to help predict which regulatory DNA elements may be associated with traits such as beak size and shape.

The platform does not make gene edits. Its role is to narrow a large search space to candidate targets that researchers can test.

About 2,300 candidates, not confirmed causes
Colossal reported roughly 2,300 candidate regulatory elements associated with beak features: 653 linked to beak size and 1,698 linked to beak thickness and breadth. These are predicted associations, not demonstrated causes. Experiments are needed to determine which elements actually influence the traits and whether changing them would produce the intended result.

The company planned to describe the work in a bioRxiv preprint. Until the candidate elements are tested, the announcement should be understood as a prioritization milestone rather than proof that the dodo’s beak can be recreated.

The proposed route to a dodo-like bird
Colossal’s plan is to introduce dodo-associated traits into cells from the Nicobar pigeon, identified as the dodo’s closest living relative. The company also reported progress toward a dodo genome that is 95% complete, using software developed for its dire-wolf project. Its earlier work produced genetically engineered gray wolves with selected dire-wolf traits—not exact genetic copies of the extinct animal.

Other announced milestones included a lipid-nanoparticle system intended to test edits directly in developing bird embryos, a 36-bird Nicobar pigeon colony in Texas, the derivation of primordial germ cells that can develop into eggs and sperm, and hatched chicken stem-cell chimeras. These developments support the broader research pipeline, but they do not mean that a dodo embryo has been produced.

What the announcement does not establish
The candidate DNA elements still need experimental validation, and multiple edits would need to work together and be inherited reliably. The aim described is a bird with important dodo-like traits, not an exact genetic recreation of the extinct species. No official hatching date was announced.

Any eventual effort to establish such birds in Mauritius would also involve habitat and ecological questions. The reported plan calls for assessment and consultation with local scientists, conservation groups and government before choosing any release site.
