There is no ‘undo’ button for extinct species

De-Destaling is a clear modern fantasy: the extremely attractive idea that we can, with only a few pipettes and computers, undo the destruction that we continue to cause the natural world. It is therefore appropriate that the first animal whose creation has announced Colossal was a terrible wolf – an animal that exists in the public imagination, mainly as a fantasy. The advisers of Colossal are the ‘Game of Thrones’ author George RR Martin and two stars of the HBO adjustment, and a press photo showed the animals that were on the iron throne of the show. Many commentators were not shocked by the advancing science of genetic manipulation, but rather because of the revelation that there were ever real wolves.

Dire Wolves had been flourishing in America for more than 200,000 years, so that so many ecological niches filled that their remains were found from Alaska to Peru. More than 4,000 wolves were taken from the La Brea -Teerputten in Los Angeles alone. They are supposed to have been hunters of the many great mammals that the America populated before the arrival of people drastically changed the ecology of the continents. They then disappeared next to their prey, one of the earliest victims of what would be a constant crisis of people driven out.

Romulus, Remus and Khaleesi started life as gray wolf cells that were processed, grown into embryos and implanted in the womb of surrogate dog mothers. The operations, which consisted of 20 modifications on 14 genes-a small fraction of the 19,000 genes that form a gray wolvengenoma based on comparisons between gray-wolf-taken and reconstructed from Dire-Wolf-DNA found in old tooth and bone fragments. (Gray wolves and terrible wolves share superficially comparable skeletons that once led scientists to conclude that they were closely related, but they are actually very different, with evolutionary lines that vary millions of years ago.) The resulting animals were larger and lighter in color than other gray wolves. The Chief Science Officer of the company, Beth Shapiro, says that this is enough to make them wolves, if you subscribe to the ‘morphological species concept’, which defines a kind of his appearance. “Species concepts are human classification systems,” she told New Scientist, “and everyone can’t agree and everyone can be right.”

Many people did not agree. The puppies call wolves, wrote the evolutionary biologist Rich Grenyer, “as a claim to have brought back Napoleon from the dead by asking a short Frenchman to wear his hat.” The scientists who specialize in Canids for the International Union for Conservation of Nature, a group that monitors biodiversity and maintains lists of endangered and endangered species, responded to the announcement of Colossal with its own press release that “the three animals produced by Colossal are not driver.” First, they said, there is no way to know if these wolves are good physical proxies for animals that nobody has seen for 12,000 years. For another, pure physicality ignores the ecology and behavior and culture of the original nasty wolf – exactly the things it made of it.

Even if Kolossal could reproduce the boring wolvengenoom, that would be very different from the reproduction of a world in which a disappeared being could thrive. It is also different from reproducing all the ways in which those beings have ever influenced their environment. Shapiro has named after the work of Colossal as “functional exhausting”-a concept that is derived from the redesigning movement-that claims for reducing the animal activities that an ecosystem has maintained, if not the exact animals they have ever carried out. It is also a play about the ecological term ‘functional extinction’, which indicates species that are still technically present in the world, but in such greatly reduced figures that they no longer eat or pollinate or otherwise have a meaningful impact on their ecosystems. It is a term that plays more and more, given that the average size of the global nature populations fell by 73 percent from 1970 to 2020.
