Revision History

Dallas-based Colossal Biosciences announced on May 19, 2026, that it hatched 26 live chickens from 3D-printed artificial eggshells — a first in avian biology. The company frames the achievement as a stepping stone to resurrecting extinct birds like the dodo and the giant moa, but independent scientists say the work lacks peer review, the term "artificial egg" overstates what was built, and that de-extinction remains far from a viable conservation strategy.
