Restoring vanishing species: the rationale behind scientists' attempts to reintroduce wolves, otters, and butterflies into their natural habitats

Get ready for some mind-blowing insights on a hot topic - the quest to bring back extinct species! In the not-so-distant future, our planet could lose up to a million species, according to a report by the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services. This massive extinction spree, happening at rates much higher than past mass extinctions, is all our doing, thanks to deforestation, monoculture agriculture, climate change, poaching, pollution, and other human-induced disasters. However, this human-driven extinction isn't just a bummer for the rest of the animal kingdom; it's also a threat to us humans. As ecosystems become unsuitable for human life, scientists have turned to a captivating solution - reintroducing extinct species back into the wild (check out our website Life for more on that).
Reintroducing extinct critters is like embarking on an exhilarating scientific adventure, complete with genetic, ecological, and logistical challenges. To understand the ins and outs of this daring endeavor, think of it as a mix of Jurassic Park vibes and The Planet of the Apes, minus the terrifying dinosaurs and intelligent simians. Animal revivals involve taking species from zoos or regions where they still exist and releasing them back into the wild. Scientists then study the steps these animals take to reintegrate themselves back into the ecosystem.
Preparing animals for their return requires a meticulous methodology. For example, it took zoologist Valentin Pazhetnov nearly two decades to develop a system for raising and releasing bear cubs orphaned by poachers. The key? Keeping the cubs in human contact for less than two weeks - any more, and they lose their fear of us humans, making survival in the wild even tougher.
In the 2010s, geneticists joined the reintroduction mission. They proposed using cutting-edge technology, like cloning, gene editing, and synthetic biology, to restore the genomes of extinct animals. The first candidates for a second life were the mammoth and the passenger pigeon. But things got even more thrilling in April 2025, when Time magazine revealed how researchers from the Colossal Biosciences project used gene editing to create three puppies of the dire wolf (Canis dirus), which went extinct 10,000 years ago.
While advancements in technology make it appear as though humans are on the verge of resurrecting extinct animals and reintroducing them into the wild, it's essential to remember that it's not as simple as flipping a switch. "Animals don't just disappear due to hunting. Their habitats change, the climate shifts, their food sources disappear, even the microbiological environment alters, and the reintroduced species can't adapt. Additionally, captive-born individuals lack the skills to forage, evade predators, or interact within a group. They require extensive preparation for survival. Another challenge is genetics. Animals are revived from a few individuals, leading to inbreeding and health issues, and a low resistance to diseases," explained our website's director of the Nature Conservation Fund, Petr Shpilenok.
Interestingly, the idea of undoing extinction is so popular that snagging funding, approval from authorities, and media coverage for such projects has become relatively easy. This popularity, however, creates difficulties for scientists in acknowledging failures. In 2000, researchers from the Australian National University analyzed 180 studies on species reintroduction and found that nearly half had questionable success rates.
Each effort to return an animal to the wild is an experiment. With modern technology at our fingertips, we can now track animals with satellite devices, assess their health, and study the causes of their demise. Our website showcases failed projects of reintroducing large mammals, reptiles, plants, and insects to shed light on the complexities of resurrecting lost species.
Key Takeaway: While cloning and genetic engineering have produced some promising results, like the dire wolves, most projects remain in the experimental stages. Long-term survival hinges on integrating scientific advancements with habitat restoration, behavioral conditioning, and embracing the reality that some reintroduction attempts may fail.
- The massive extinction of up to a million species, as reported by the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services, is a wake-up call for health-and-wellness, prompting scientists to explore methods to restore extinct species and preserve the environment.
- In order to combat extinction, experts are turning to innovative therapeuties-and-treatments, such as cloning, gene editing, and synthetic biology, as seen in the attempted resurrection of the dire wolf by researchers at Colossal Biosciences in 2025.
- However, the journey to restore extinct species is complex, as shown by Valentin Pazhetnov's work with bear cubs orphaned by poachers, which required specific methodology, including limiting human contact to less than two weeks.
- While the allure of bringing back extinct species is undeniable, it is crucial to understand that the process is fraught with challenges, including habitat shifts, climate change, genetic issues, and the need for extensive behavioral conditioning before release into the wild, as pointed out by Petr Shpilenok, the director of the Nature Conservation Fund.
- Ultimately, the success of reintroduction projects depends on the integration of scientific advancements with habitat restoration, behavioral conditioning, and a willingness to acknowledge and learn from failures, as demonstrated by the numerous case studies on the Life website that highlight both successes and unsuccessful attempts at reintroducing various species.
