The dodo bird isn't coming back anytime soon. Nor is the woolly mammoth. But a company working on technologies to bring back extinct species has attracted more investors, while other scientists are skeptical such feats are possible or a good idea.
Colossal Biosciences first announced its ambitious plan to revive the woolly mammoth two years ago, and on Tuesday said it wanted to bring back the dodo bird, too.
The Dallas company, which launched in 2021, also announced Tuesday it had raised an additional $150 million in funding. To date, it has raised $225 million from wide-ranging investors that include United States Innovative Technology Fund, Breyer Capital and In-Q-Tel, the CIA's venture capital firm which invests in technology.
The dodo's closest living relative is the Nicobar pigeon, said Beth Shapiro, a molecular biologist on Colossal's scientific advisory board, who has been studying the dodo for two decades. Shapiro is paid by the Howard Hughes Medical Institute, which also supports The Associated Press' Health and Science Department.
Because animals are a product of both their genetics and their environment - which has changed dramatically since the 1600s - Shapiro said that “it's not possible to recreate a 100% identical copy of something that's gone.” “And where on Earth would you put a woolly mammoth, other than in a cage?” asked Pimm, who noted that the ecosystems where mammoths lived disappeared long ago.
