Colossal adds funding as it makes strides to revive dodo bird

Colossal Biosciences raised $120 million, extending its Series C to $320 million and valuing the company at $10.3 billion to advance dodo bird de-extinction.

  • Colossal Biosciences announced on September 17 that its scientists successfully grew pigeon primordial germ cells, a key step toward dodo revival in Texas.
  • The achievement follows the company's 2021 founding and aims to use gene-edited surrogates like chickens to breed dodos, with critics noting limits to true resurrection.
  • The company plans to inject edited cells from the Nicobar pigeon, the dodo's closest relative, into surrogate chickens and also targets the extinct moa bird.
  • Colossal has raised $120 million more in funding, boosting its valuation past $10.3 billion, with CEO Ben Lamm describing the team's achievement as a major step forward for efforts to bring back the dodo.
  • This progress supports plans for dodo rewilding in Mauritius, while the firm’s broader goals include advancing avian conservation and accelerating de-extinction projects.
