Colossal Biosciences Launches GenoMorph AI for Dodo De-extinction
New AI platform identifies regulatory DNA targets to guide dodo gene-editing efforts.
1GenoMorph Platform Unveiled
Colossal Biosciences introduced GenoMorph on October 14, 2026, to identify gene-editing targets for species lacking comprehensive genomic records. The system analyzed regulatory DNA elements to predict physical traits in the dodo. By focusing on non-coding regions, the platform identifies switches that control developmental processes, rather than just protein-coding sequences of DNA.
2Regulatory DNA Mapping Strategy
The team built an avian regulatory atlas using samples from chickens, quail, ducks, and pigeons across six embryonic stages. By integrating CT-derived skull measurements from 70 bird species and 541 anatomical landmarks, the platform predicts how regulatory elements influence beak size. This data-heavy approach addresses the scarcity of surviving dodo genomic material.
3Identifying Dodo Candidate Elements
GenoMorph identified 2,300 candidate regulatory elements associated with dodo beak morphology, specifically 653 for size and 1,698 for thickness and breadth. These findings serve as prioritized targets for experimental validation. Colossal emphasizes that these elements are candidates, not confirmed causes, requiring further testing to verify their role in craniofacial development.
4Technical Accuracy and Methodology
Presented at the 2026 Society for Molecular Biology and Evolution, the method uses a convolutional neural network trained on chromatin-accessibility data. The model achieved an average prediction accuracy of 0.863 within species. Researchers identified the gene CACHD1 as a top candidate, showing elevated expression in long-beaked species during frontonasal process development.
5Iterative Dodo Genome Assembly
Colossal improved its dodo genome assembly using an iterative method developed for its dire wolf project. By progressively updating the reference genome with newly mapped DNA, the company minimized bias toward the Nicobar pigeon. Currently, 95% of the dodo genome bases are covered at least 5-fold, with an average coverage of 65-fold.
6Nicobar Pigeon Colony Expansion
The company expanded its Texas-based Nicobar pigeon colony to 36 birds to support de-extinction research. Scientists successfully derived primordial germ cells from these birds, which are essential for creating heritable genome edits. These cells will eventually carry selected dodo traits into future generations, bridging the gap between genomic prediction and biological reality.
7Phenotype Screening and Validation
Colossal hatched the first chimeric chickens using avian embryonic stem cells, confirming that cultured cells can integrate into host embryos. This system is being adapted for pigeons to test edited stem cells for phenotypic effects. Additionally, a new lipid-nanoparticle delivery platform introduces CRISPR tools into embryos, improving viability over traditional methods.
8Future of De-extinction Science
The integration of AI with comparative genomics represents a shift in de-extinction methodology. By moving from ancient DNA analysis to functional validation in living surrogates, Colossal aims to translate predicted traits into actual biological outcomes. The success of these combined technologies will determine the feasibility of restoring extinct species' defining anatomical features.
