De-extinction firm says it has hatched first chicks from artificial eggs

The company said the membrane lets embryos develop in room air and could help conservationists rescue endangered birds.

  • Texas-Based biotechnology firm Colossal Biosciences announced the successful hatching of 26 healthy chicks using a 3D-printed, silicone-based artificial eggshell system.
  • The breakthrough utilizes a specialized, semi-permeable membrane that successfully replicates natural gas exchange and moisture retention without requiring dangerous amounts of supplemental oxygen.
  • Company executives stated that the scalable system is a critical engineering milestone designed to eventually bypass the biological surrogacy limits of birthing massive extinct avian species like the dodo or the 12-foot-tall giant moa.
  • Outside evolutionary biologists tempered the achievement by noting that while the protective shell technology is an impressive bioengineering feat, it relies on real fertilized embryos poured into the system rather than being a entirely synthetic egg.

Is it possible to return to life birds that no longer exist? That is what a de-extinction company from Texas is doing. They achieved the hatching of some chicks from an artificial egg. They have discovered the way to develop a bird embryo that does not have to be in its biological shell and without the need for oxygen in an additional way. Their goal is to return to birds as famous as dodo and moa. So this scientific advance would be incredible …
