Embryo development.
A multibillion-dollar de-extinction company believes it is one step closer to resurrecting New Zealand's largest and long-extinct flightless bird.
Colossal Biosciences - headquartered in Texas - is heralding a "major breakthrough" in its development of an artificial egg that it says is crucial to giant moa - which died out around 500 years ago - once again walking the earth.
The company said it had successfully hatched 26 chickens from a novel artificial egg, designed to be reproduced at scale and at any size.
The biotech company, which recently claimed to have resurrected the 'dire wolf', has courted controversy with its de-extinction projects, with critics questioning the ethics of de-extinction and whether it is even a valid claim.
