SortEmbra leaving a fantasy saga or a documentary on the glacial era, yet it is reality. The legendary Say wolf (or enocono, in Italian), A wolf extinct for over 10,000 yearshe returned to walking on earth. A “de-extinction” pioneering company created by the American hi-tech company Colossal Biosciencesrecently jumped to the honors of the chronicles also thanks to a cover dedicated on Time magazine. Three incredibly special puppies today represent the promise of a future where science and nature intertwine in unpublished ways. Not without consequences on the ethical level.
How the “de-astinction” of the Say wolf?
How was it possible? Scientists of Colossal they have DNA fragments extract from ancient finds – a 13,000 -year -old tooth and an ear bone of 72,000 – combining them with the genetic heritage of the gray wolfhis most closest relative. Through sophisticated Genetic editing and cloning techniquesusing progenitor cells extracted from the blood and canine surrogate mothers, the impossible has become reality. A complex process culminating with the birth, in October 2024 of three healthy puppies.
The life of the three wolf puppies
Their names evoke myths and guerry queens: Romulus, Remus and the little sister Khaleesi (yes, a tribute to game of Thrones). The three young people Say wolf grow in a protected sanctuary of about 800 hectares. They are already imposing (they measure almost 1.2 meters in length and weigh over 36 kg. From adults, they could reach 180 cm and exceed 70 kg) and show a instinctively wild behavior, wary of man.
Hear them howl, as Matt James tells Colossalit was a “shocking and creepy” moment. But their future raises questions: 800 hectares (i.e. 8 square kilometers) of land are sufficient for animals whose natural territory extended for thousands of square kilometers? They will ever be able to live a truly “wild” life What socially complete in semi-fault?
Colossal wants other animals to “de-establish”
The goal of Colossal goes beyond the Say wolfaiming for “de-Estinuere” also the woolly mammoth, the dodo and the Tasmania tiger. A company not exempt from criticism. The bioethasticist Robert Klitzman warns: «There is the risk of death. There is the risk of serious side effects … there will be spontaneous abortions “. There animal suffering In the cloning process it is a concrete concern. Also, as the Lupi Rick McIntyre expert, the Say wolf Yes extinct because it specializes in megafauna now disappeared. Will it adapt to today’s ecosystems or will it be destined to fail again?
The risks of manipulating nature
History teaches that the introduction or the manipulation of species can have unexpected and disastrous consequences (Think of the toad of the rods in Australia, which is threatening several native species). Bringing to life extinct species, however fascinating, involves the responsibility of potential ecological imbalances. Colossal is defined as an “evolutionary force”, but the question remains: we are ready to manage the power to rewrite the rules of naturewith all the unknowns that this entails? The debate has just begun.
