The legendary bird "Dodo" has been extinct for more than three centuries. Now an American biotechnology company said that its team has successfully broken through the bottleneck of genetic recombination through a self-developed AI platform and has taken a key step towards resurrecting the Dodo. The ultimate goal is to return it to its hometown of Mauritius.

"Reuters" reported that the dodo originally lived in the Indian Ocean island country of Mauritius. It weighed 23 kilograms, was huge and had no flight ability. It was completely extinct in 1662 due to human overhunting and invasion of alien species in the 17th century, becoming a representative symbol of man-made species extinction.

Colossal Biosciences, headquartered in Dallas, USA, is committed to "de-extinction" technology, and its target list includes species such as the dodo, woolly mammoth, thylacine, blue antelope and moa. In the past, the company edited the genes of modern gray wolves to create individuals with the characteristics of Ice Age predators, and claimed to have achieved the "resurrection of dire wolves," sparking widespread discussion and controversy in the academic community.

Beth Shapiro, the company's chief scientific officer, pointed out on Wednesday that although the team has pieced together 95% of the dodo's genome, it is difficult to clarify which sequences determine the dodo's unique appearance using a single genome alone. The team used a newly developed AI platform to screen out key gene targets that may affect the dodo's unique craniofacial characteristics.

The next step for the research team is to edit and introduce the selected gene targets into the cells of the Dodo's closest living relative, the Nicobar dove. The green pigeon is native to some islands in Southeast Asia. Unlike the dodo, it has the ability to fly. The company has currently bred 36 green doves in Texas, but has not announced a timetable for hatching dodos.

Ben Lamm, CEO of Pangran Biotechnology, said that the company is working closely with the Mauritian government and international conservation groups to remove local exotic predators and restore the ecological environment. After the habitat assessment is completed, the company will make every effort to promote the official return of the dodo to the wild.
