De-Extinction: Exploring the Possibility of Bringing Back Extinct Species through Genetic Rescue

The possibility of bringing extinct animals back to life, known as de-extinction, has been a topic of scientific research and ethical debate for several years. With advances in genetic engineering and other related technologies, it is becoming increasingly feasible to recreate extinct species using DNA from fossil remains or other preserved samples.


One such example is the case of the Dodo bird, a species that went extinct in the late 17th century. While there are no complete specimens of the bird left, scientists have been able to extract fragments of Dodo DNA from fossils and museum specimens. Using this genetic material, researchers are exploring the possibility of bringing the Dodo back to life through a process called "genetic rescue".





Genetic rescue involves using DNA from closely related species to recreate the genetic code of the extinct animal. In the case of the Dodo, scientists are examining the genetic makeup of its closest living relative, the Nicobar pigeon, to identify the genes that were responsible for its unique characteristics. By comparing the genomes of these two species, scientists can identify the specific genes that need to be edited or replaced to recreate the Dodo's traits.


While the idea of bringing extinct animals back to life may seem exciting, there are many ethical and practical considerations that must be taken into account. For example, some argue that resources should be focused on conserving and protecting endangered species rather than recreating those that have already gone extinct. Others point out that the environmental conditions that supported the Dodo may no longer exist, making it difficult to reintroduce the species into its former habitat.


Overall, the concept of de-extinction raises many complex and controversial issues. While the technology to bring extinct species back to life is rapidly advancing, it will be important for scientists and policymakers to carefully consider the potential risks and benefits of such efforts.
