A breakthrough in artificial egg technology has successfully hatched healthy chicken chicks, bringing scientists one step closer to reviving extinct birds like the dodo and the giant moa. At Colossal Biosciences in Dallas, bioengineers have developed 3D-printed plastic eggs that can support the growth of embryos, a crucial step in the company’s mission to bring back extinct species.
Trevor Snyder, a bioengineer at Colossal, demonstrated the artificial egg, which contains a chicken embryo with visible eyes, heartbeat, and developing wings and legs. The company’s goal is to use this technology to resurrect the dodo and the giant moa, which went extinct hundreds of years ago. The eggs of these birds were larger than those of their closest living relatives, making it impossible for modern birds to incubate them.
Artificial Eggs for Extinct Species
The artificial eggs are designed to replicate the functions of natural eggs, with a honeycomb structure that allows oxygen to enter while keeping the contents from leaking out. Colossal’s plan is to use gene-edited cells from the Nicobar pigeon to create dodo embryos and from the emu to create moa embryos, which will be placed inside the artificial eggs. The company has already hatched over two dozen chickens using this technology and is working on larger eggs that can accommodate the dodo and moa embryos.
While some scientists are thrilled about the potential of artificial eggs to help save endangered species, others raise concerns about the ethics and safety of reviving extinct species. Critics argue that the recreated animals may suffer and become extinct again due to changes in their habitats or cause unpredictable damage to the environment.
Implications and Reactions
The breakthrough has sparked a debate about the possibility of bringing back extinct species, with some experts questioning whether it is ethical and safe. Nic Rawlence, an associate professor of ancient ecology, argues that Colossal is not truly reviving extinct species but rather creating genetically engineered facsimiles. Despite the controversy, Colossal’s chief biology officer, Andrew Pask, believes that the technology has the potential to make a significant impact on conservation efforts.
As the company moves forward with its plans to revive extinct species, the scientific community will be watching closely to see the outcomes and implications of this technology. The success of artificial eggs in hatching healthy chicks is a significant step forward, but the broader question of whether it is possible to truly bring back extinct species remains to be seen.
