Colossal Biosciences, a biotech company known for its ambitious de-extinction projects, has announced a breakthrough in hatching live chicks from an artificial environment. The company used a 3D printed lattice structure that mimics an eggshell to successfully hatch 26 baby chickens. This development has drawn mixed reactions from the scientific community and critics of the company’s mission to resurrect extinct species.

Innovative Technology

The artificial eggshell technology, as described by Colossal’s CEO Ben Lamm, could potentially be scaled to genetically modify living birds to resemble extinct species, such as New Zealand’s South Island giant moa. The moa’s eggs are significantly larger than a chicken’s, making natural laying impossible for modern birds. Lamm stated, “We wanted to build something that nature has done a pretty good job of developing and make it better and scalable and even more efficient.”

Independent scientists, while acknowledging the innovation, have pointed out that the technology lacks certain components to be considered a complete artificial egg. Vincent Lynch, an evolutionary biologist at the University at Buffalo, noted that while the technology might aid in creating genetically modified birds, it does not equate to reviving extinct species like the moa.

Scientific and Ethical Considerations

To hatch the chicks, Colossal scientists poured fertilized eggs into the artificial system, added calcium, and monitored the embryos’ development in real-time. Despite the technological advancements, some scientists remain skeptical about the feasibility of de-extinction. Nicola Hemmings, a researcher in bird reproductive biology, emphasized that producing chicks from artificial vessels is not entirely new and has been achieved with simpler technologies in the past.

Bioethicist Arthur Caplan from New York University raised concerns about the ecological implications of introducing resurrected species into modern environments. He questioned the viability of such animals surviving in landscapes vastly different from their original habitats.

While Colossal’s efforts are groundbreaking, the company acknowledges the long road ahead before attempting a full-scale resurrection of extinct species. This includes comparing ancient DNA with genomes of living birds and developing larger eggshells suitable for species like the moa.

Some scientists, like Hemmings, argue that conservation efforts might be better directed towards preserving endangered species rather than reviving those already extinct. “My personal interests lie more in preserving what we’ve got than trying to bring back what is already gone,” Hemmings said.
