Artificial eggshell comes first in attempt to revive giant flightless moa
Colossal Biosciences has made progress towards reviving the extinct moa by creating an artificial eggshell. The company claims its new incubation system could be scaled up to produce a bird as large as the moa. However, many scientists remain skeptical about the feasibility and ethical implications of such de-extinction efforts.
