The giant, flightless bird that roamed New Zealand before its extinction about 600 years ago is the next species on a controversial list of “passive” targets by biotechnology company Colossal Biosciences.
Colossal announced on Tuesday (July 8th) that its scientists and local indigenous partners will “revive” South Island giant MOA (Dinornis Robustus) through genetic engineering within the next decade. The D. robustus stands up to 12 feet (3.6 meters) high, and is the largest species of nine known MOAs, all of which are believed to have been extinct due to human hunting.
“We’re bringing home bird dinosaurs,” the company said in an Instagram post.

Colossal previously claimed it had revived Dire Wolf (Aenocyon Dirus), an ice age predator that had disappeared more than 10,000 years ago, but what was revealed in April sparked criticism from many experts. Colossal also has plans to “revive” wool mammoths, dodos and tyracins (wolf-like creatures also known as Tasmanian tigers), but these projects are equally controversial.
“With many taxa now, it is unacceptable that this is not considered okay just because it may be possible to regenerate animals in the future,” Trevor Worthy, a vertebrate paleontologist and associate professor at Flinders University, Australia, who is not associated with Colossal, told Live Science emailed.
Colossal’s new announcement quickly attracted criticism from researchers. Researchers ultimately accused the bird it produces of not acknowledging that it is a hybrid with MOA-like properties, not a MOA.

Philip Seddon, a professor of zoology at the University of Otago in New Zealand, told the National Science Media Centre (NZSMC). “The end result is not a MOA. It’s a unique treasure created through thousands of years of adaptation and change.”
Following the announcement by Dire Wolf, Colossal chief scientist Beth Shapiro revealed in an interview with a new scientist that the animals are in fact “20 grey wolves with edits” and “cannot regain the same species as the living ones.” Shapiro also claimed that Colossal never tried to hide these facts, but when LiveScience contacted Colossal for comments, the spokesman doubled the company’s original claim that it had revived the disastrous wolves.
In the MOA announcement, Shapiro says Colossal will “return MOA back to life,” while the company’s co-founder and CEO Ben Lamm says scientists will “return it back to the ecosystem.”
“In spite of the final reconstruction of Colossal Biosciences’ final wolf detone, there is no hint in the recent press release that can be expected to be an ecological alternative to New Zealand’s MOA, in fact, creating ecological substitutions using GMOs.” Seddon told NZSMC.
To replicate the giant MOA, scientists extract DNA from the remaining bones of all nine species and compare it with the DNA of living birds, Shapiro told Time Magazine. She said that researchers can then identify specific genetic traits of MoAS and make those changes to the genome of EMU or Tinamou, the closest living relatives of MoAS.
“It makes sense to use Tinamous and Emus as templates to align the DNA of the MOA,” Worthy said in his email. “Many studies on DNA show that Tinamous is a sister species to MoA. EMU is a similarly close relative.”
GMO-modified tinamou or EMU cells are embedded on a surrogate from one of two birds and become pregnant. The announcement suggests that hatching will not be released into the wild or stored in zoos, suggesting that birds will live in fenced nature reserves.
He said that if a bird escapes, value poses no danger to humans. “Perhaps, unless you try to hold it, Mores wouldn’t consider a human as a threat, and by scaring it, you’re likely to get kicked and hurt badly,” he said.
Colossal says the Moa De-emptinction will benefit endangered birds along the way. For example, it can inform the development of artificial eggs.
“Along the path to annihilation, knowledge will be questionable,” Worth said. “We’ll get [unprecedented] About DNA knowledge of target animals and extinct groups such as MOA [be] It’s very interesting about their evolution, their relationships and more. ”
But Stuart Pym, a professor of conservation ecology at Duke University, North Carolina, told Time magazine that animals, like extinct species, remain “right from Frankenstein.”
