Back from the Brink: How Colossal Biosciences is Resurrecting the Dodo

Each legend gets a remix eventually, and the dodo, history’s most famous no-show, is finally getting its own. Colossal Biosciences, the Dallas outfit that put dire wolves back on the map and has the woolly mammoth on deck, recently released a stack of breakthroughs that move the dodo from punchline to production. The headliner is GenoMorph, an in-house AI platform built to figure out what made the dodo look like a dodo, starting with that gloriously oversized, hooked beak.

Think of it this way: genes are the instruments, but they don’t decide how loud each one plays. Regulatory DNA does that job, the faders on a mixing board that set when, where, and how strongly a gene kicks in. Tweak the levels and the same band produces a completely different song. Colossal’s team built a massive reference library to learn those levels, sampling chicken, quail, duck, and pigeon embryos across six developmental stages, then pairing that with genomes and CT-scanned skulls from more than 70 bird species, mapped at 541 anatomical points. GenoMorph sifted through it all and flagged roughly 2,300 candidate switches tied to beak size and shape.

"De-extinction is as much a data problem as a biology problem,” said Ben Lamm, CEO and Co-Founder of Colossal. “Because so few dodo genomes survive, we cannot rely on the population-level comparisons available for many living species. Our GenoMorph platform provides another path: it learns how regulatory DNA shapes living birds, then identifies the genetic switches that may have contributed to the dodo’s distinctive anatomy. This is more than a solution for the dodo. It provides a repeatable approach for extinct species whose genomic records are similarly limited.”

However, only a handful of dodo genomes survive, which would stop most labs cold. GenoMorph sidesteps that by learning from the living. That same playbook could work for any extinct or endangered bird with a thin genetic record. Colossal is already proving its tech travels. A genome-assembly method it built for the dire wolf, published in Cell Genomics, has now filled major gaps in the dodo’s DNA, letting stray fragments of ancient code slot into place again and again.

The hardware is coming together too. Colossal’s Texas colony of Nicobar pigeons, the dodo’s closest living relative, has grown to 36 birds, and their eggs have yielded germ cells that can eventually become sperm and eggs, the path to passing edits down the line. The team has also hatched chimeric chickens, birds carrying lab-grown stem cells embedded within their bodies, proving a key step in the process actually works. And a new lipid-nanoparticle system, tiny fat bubbles that ferry gene-editing tools into developing embryos, has worked in chickens, rock doves, and ducks. “It establishes a repeatable framework for connecting ancient genomes to extinct traits,” said Beth Shapiro, Colossal’s chief science officer.

Put it together, and you have a full studio: an AI that reads the sheet music, a pigeon colony to play it, and the tools to lay down every track. The candidates are already being tested, with the strongest headed into Nicobar pigeon cells for exact editing. For more than 300 years, the dodo has been shorthand for gone forever. Colossal is busy producing its comeback.
