No “Undo” Button for Extinct Species

Elimination presents a distinctly modern fantasy. It’s a captivating notion that, with merely a pipette or a computer, we can reverse the damage that continues to afflict the natural world. The first creature featured by Colossal is a forlorn wolf, an entity primarily born from imagination, fitting seamlessly into the realm of fantasy. Colossal’s advisory team included notable figures like George R.R. Martin, author of “Game of Thrones,” along with the HBO series adaptation, with promotional images depicting these creatures perched on the show’s Iron Throne. Many observers were taken aback upon learning that these forlorn wolves once roamed the earth as real animals, rather than being products of advanced genetic engineering.

For over 200,000 years, these forlorn wolves thrived across America, carving out a rich ecological niche; their remains have been found from Alaska to Peru. Over 4,000 wolves have been excavated from the La Brea Tar Pits in Los Angeles alone. They were among the large mammal hunters who roamed America before humans arrived and are believed to have significantly impacted the continent’s ecology. Eventually, they vanished along with their prey, becoming early victims of the ongoing crisis of human-induced extinction.

Romulus, Remus, and Khaleesi were edited and cultivated into embryos, originating from grey wolf cells implanted in the uterus of a surrogate dog. This genetic modification involved 20 alterations across 14 genes (a minor segment of the 19,000 genes that constitute the Grey Wolf genome), guided by a comparison between the Grey Wolf genome and DNA extracted from ancient tooth and bone fragments. While grey wolves and forlorn wolves share superficial skeletal similarities, scientists have determined that they are fundamentally distinct, with their evolutionary paths diverging millions of years ago. Beth Shapiro, the company’s chief science officer, argues that subscribing to the “concept of morphological species” suffices to categorize them as forlorn wolves if defined by appearance. “The notion of species is merely a human classification system,” she stated to New Scientist.

Many individuals voiced their disagreement. Referring to a puppy as a forlorn wolf is akin to suggesting that by donning a hat, a short Frenchman could resurrect Napoleon. Experts in canids from the International Union for Conservation of Nature, which monitors biodiversity and maintains a list of endangered species, responded to Colossal’s announcement with their own statement, asserting that “the three animals created by Colossal are not forlorn wolves.” They noted that there’s no real way to ascertain if these wolves accurately represent animals that have been absent for 12,000 years. Furthermore, reducing them to mere physicality overlooks the ecology, behavior, and culture of the original forlorn wolves.

Even if Colossal could replicate the Kree-Wolf genome, it would vastly differ from reinstating a world where such an extraordinary creature could thrive. It also fails to encompass the various ways these beings once influenced their environment. Shapiro refers to Colossal’s research as “functional detension,” a term borrowed from the rewilding movement. This ties into the ecological concept of “functional extinction.” These animals technically exist but, with their drastically reduced numbers, they can no longer play a role in eating, pollinating, or impacting their ecosystems meaningfully. This term has gained urgency in light of the 73% decline in global wildlife populations from 1970 to 2020.
