(CNN) – A Texas company says it’s a step closer to bringing back the dodo bird from extinction.
The dodo bird has been extinct for about 400 years.
Wednesday, Colossal Biosciences announced that it is using genetic engineering to try and create a living, breathing version or ‘copy’ of the bird.
The company says it has the technology to successfully culture specialized cells from Nicobar pigeons, the dodo’s closest living relative.
They say it will take at least five to seven years for the project to play out.
The company says it is also working on bringing back other extinct animals, including woolly mammoths and Tasmanian tigers.
