The US company Colossal Biosciences claims to have successfully incubated a bird in an artificial egg system until it hatched. In a press release, the company states that this technology allows a bird embryo to develop fully outside the shell of a biological egg, and could be used to bring back extinct bird species such as the giant moa from New Zealand’s South Island.

Colossal Biosciences has announced the creation of genetically modified mice with characteristics reminiscent of the fur of extinct mammoths, such as fur colour, texture and thickness. The non-peer-reviewed results were shared today in the BioRXiv prepublication repository.
