Colossal Biosciences has developed an artificial eggshell aimed at reviving the extinct moa, a giant flightless bird from New Zealand. While the company claims this innovation could facilitate the hatching of moa-sized birds, scientists express skepticism about the feasibility and ethical implications of such de-extinction efforts.
- 01The artificial eggshell is a silicone membrane designed to allow oxygen transfer similar to that of a chicken eggshell.
- 02Moa eggs were approximately 80 times the volume of a chicken egg, presenting challenges for using avian surrogates.
- 03Colossal's previous claims about de-extincting the dire wolf and woolly mammoth have drawn criticism for lacking scientific rigor.
- 04Experts like Dr. Louise Johnson emphasize the need for peer-reviewed research to validate Colossal's claims.
- 05Ethical concerns arise regarding the ecological impact of potentially releasing genetically modified birds into the wild.

Colossal Biosciences, a company focused on de-extinction, has announced a significant advancement in its efforts to revive the extinct moa, a flightless bird that once roamed New Zealand. The company has created an artificial eggshell, which it claims can support the incubation of a bird as large as the moa. According to Prof. Andrew Pask, the chief biology officer at Colossal, this novel shell-less culture system is both scalable and biologically accurate. However, the announcement has sparked skepticism among scientists due to the lack of detailed scientific data. Experts point out that while it is possible to hatch chicks from artificial eggshells, survival rates are often low due to inadequate oxygen supply. Colossal's silicone membrane aims to address this issue by allowing oxygen to pass through at rates similar to natural eggshells. Despite these advancements, challenges remain, particularly the difficulty of recreating a complete moa genome, as the species went extinct around 600 years ago. Ethical questions also linger regarding the ecological implications of reintroducing genetically modified birds into their former habitats.
