Colossal Biosciences, fresh off its controversial dire wolf "resurrection" project, has announced an ambitious plan to "de-extinct" nine species of the giant moa bird. The moa, a flightless bird native to New Zealand, went extinct centuries ago due to hunting and habitat loss. While Colossal Biosciences has attracted significant funding and attention with its de-extinction efforts, many scientists remain skeptical about the feasibility of resurrecting extinct species. The challenges include obtaining viable DNA, understanding the complex ecological roles of extinct animals, and ensuring suitable habitats for their reintroduction. The announcement has reignited the debate surrounding the ethics and practicality of de-extinction.
