Colossal Biosciences Aims to Revive the Giant Moa
Colossal Biosciences, a biotechnology company based in Dallas, Texas, is undertaking the ambitious project of bringing back the moa, a now-extinct giant bird from New Zealand. The effort is a collaboration with director Sir Peter Jackson and Māori research organizations.
What Was the Moa?
Moa were flightless birds endemic to New Zealand, resembling ostriches or emus but distinct in their evolutionary lineage. They were the largest herbivorous birds in new zealand’s ecosystem, consuming leaves, fruits, and other vegetation. Moa varied in size, with some species reaching up to 3.6 meters (12 feet) in height and weighing around 226.7 kg (500 lbs). The largest species, the South Island giant moa (Dinornis robustus), could grow to 3.8 meters (12.5 feet) tall and weigh over 220 kg (485 lbs). Britannica
The De-Extinction Project
The project, coordinated by the Ngāi Tahu Research Center in collaboration with the University of Canterbury, aims to utilize advanced genetic engineering techniques to recreate the moa. This approach mirrors the work being done to revive the woolly mammoth and the Tasmanian tiger by Colossal Biosciences. Colossal Biosciences
Genetic Reconstruction Process
The process involves several key steps:
- Genome sequencing: Scientists plan to sequence and reconstruct the genomes of the nine known moa species.
- Comparative Genomics: They will also sequence the genomes of the moa’s closest living relatives: the emu and the tinamou (a smaller, chicken-like bird).Moa diverged from the ancestors of tinamou around 58 million years ago, and from emu ancestors around 65 million years ago, making the reconstruction more challenging.
