Chicks from artificial eggshell spark moa revival hopes and ethical debates

Colossal Biosciences announced it hatched 26 chicks from a 3D-printed artificial eggshell as part of its de-extinction efforts to resurrect the extinct 12-foot moa. The system uses a membrane-enabled shell but omits other egg components, prompting scientists to note it is not a true artificial egg and that reviving the moa remains speculative. If progress continues, challenges include validating DNA, scaling to larger eggs, ecological fit, and ethical considerations, though the company argues the platform could aid endangered birds and embryo rescue.

Breakthrough artificial eggs hatch chicks, boosting de-extinction hopes

Colossal Biosciences hatched 26 healthy chicks from a 3D-printed titanium artificial egg with a silicone membrane, proving a shell-free avian development system that could aid conservation and pave the way for reviving extinct birds like the moa and dodo; they aim for moa revival in New Zealand in the early- to mid-2030s, in collaboration with Ngāi Tahu and Peter Jackson, with future tests on larger eggs (emu/ostrich) to scale the technology.

Colossal plots bluebuck revival using a roan surrogate and gene editing

Colossal Biosciences unveiled a plan to revive the extinct African bluebuck by editing roan antelope DNA and using a roan as a surrogate mother, aided by breakthroughs like roan ovum pickup and roan-derived induced pluripotent stem cells; the company hopes for a birth in coming years and a future reintroduction within the bluebuck’s historic Southern Africa range, though conservation scientists question the practical value and ecological viability of such de‑extinction efforts.

Colossal Eyes 2028 Birth for Bluebuck in De-Extinction Drive

Colossal Biosciences says it has bluebuck DNA, has mapped it, and is in the final phase of genomic editing for a 2028-ish birth via a surrogate, part of a broader de-extinction portfolio aimed at re-wilding in native habitats with government and indigenous partners; critics warn of ecological risks and question practicality, while the company says the work focuses on ecosystem benefits rather than zoos.

Colossal’s de-extinction bid stirs science and ethics debate

Dallas-based Colossal Biosciences is pursuing revival of extinct species—including dire wolves and the dodo—using ancient DNA and CRISPR. The effort has drawn praise for pushing conservation tech and public engagement, but also sharp criticism from scientists who question feasibility and ecological risks, warn against conflating revived animals with extinct ones, and worry about undermining habitat protection; supporters see potential conservation benefits and genetic diversity applications, while critics urge caution and rigorous science.

Mammoth Comeback: Colossal’s Genome Quest to Rebuild an Ice-Age Giant

Colossal Biosciences is assembling hundreds of mammoth genomes to guide edits in the Asian elephant genome, testing changes in mice before attempting embryonic cloning to produce mammoth-like calves (potentially by 2028). The project aims to restore ecological roles of mammoths and advance conservation tools, but it faces scientific and ethical debate about whether this constitutes true de-extinction and how it would be implemented in Arctic ecosystems.

Colossal's Genetically Engineered Animals: Reality or Fiction?

Colossal Biosciences, led by Ben Lamm, claims to have made progress in de-extincting species like the dire wolf and woolly mammoth through genetic engineering, but scientists remain skeptical, arguing that these are not true resurrected species but genetically edited animals that do not fully replicate the original extinct species. Critics warn that overhyping such claims can undermine scientific trust and emphasize that traditional conservation efforts remain essential.

Neanderthals Could Be Recreated in 20 Years: Should We?

Scientists are close to potentially bringing back Neanderthals within 20 years using advanced genetic technologies like CRISPR, but this raises significant ethical, legal, and practical concerns, including the feasibility of the process, the well-being of any resurrected individuals, and the moral implications of creating a new human-like species. Most experts agree that such efforts are currently unwise and ethically problematic, emphasizing the importance of preserving existing human and animal species instead.

Scientists and startups make strides toward bringing back the dodo bird

Scientists at Colossal Biosciences have achieved a major breakthrough in de-extinction by successfully growing primordial germ cells from pigeons, the closest relatives of dodos, marking a pivotal step toward potentially bringing the dodo back to life within the next five to seven years using gene editing and surrogate chickens. The project aims to reintroduce the species to Mauritius, but experts caution about ecological and ethical challenges involved.
