Texas-based de-extinction company Colossal Biosciences says it has successfully hatched live chicks from what it describes as an artificial eggshell created for an engineered reproductive process. Multiple outlets report the company’s announcement that chicks hatched in an artificial environment, which the company presents as a technical step relevant to future de-extinction efforts—potentially helping resurrect species that are no longer alive.
However, several reports also note that independent scientists and critics urge caution. Courthouse News and Phys.org describe mixed reviews, including concerns that the work may not yet meet all criteria for a “fully” artificial egg. In particular, scientists cited in these accounts say the approach may lack certain components that would be needed to claim a complete artificial egg system.
Overall, the announcements highlight progress in producing live embryos and chicks under laboratory or artificial conditions, while emphasizing that verification by independent experts and clearer technical details are needed to confirm how fully artificial the eggshell and surrounding components are, and what it means for de-extinction goals.
