It then bred with a hen, which gave birth to a chick.Ĭolossal plans to go down a similar route. Scientists have previously introduced PGCs to create a chicken fathered by a duck – for which a duck embryo was injected with chicken PGCs, producing an adult duck with the sperm of a rooster. This is a vital step in creating hybridized animals through reproduction. They are now researching to see if these cells (called primordial germ cells, or PGCs) can turn into sperm and eggs. Geneticists at Colossal have found cells that act as a precursor for ovaries or testes in the Nicobar pigeon can grow successfully in a chicken embryo. In addition, the company says it has now sequenced the genome of the solitaire, an extinct relative of the dodo from Rodrigues Island, close to Mauritius, and the Nicobar pigeon, the dodo’s closest living relative, which resides on islands in Southeast Asia spanning the Indian and Pacific Oceans. The full genome of the dodo has been sequenced by Beth Shapiro, lead paleogeneticist at Colossal. Exactly when it will be able to do so remains unclear, but fresh details regarding how it plans to recreate the species have been revealed. But according to the partners, its return to Mauritius could benefit the dodo’s immediate environment and other species.Ĭolossal first announced its intention to resurrect the dodo in January 2023. The dodo has been extinct since 1681 a combination of predation by humans and animals introduced by humans led to its downfall, turning it into a textbook case for extinction.
