As I was reading, I thought it was quite timely that news about the “re-emergence” of an extinct species was announced: the dire wolf. I will go a bit into that later; however, I want to discuss The Sixth Extinction: An Unnatural History by Elizabeth Kolbert first. One of the draws that led me to this book was our current understanding of extinction. It was just amazing that there was a universal belief that no species ever died out, up until the 1700s, when people would find fossils and bones that did not match any species that were alive at the time. We also didn’t have the meteoroid hypothesis about what killed off the dinosaurs until the 80s. It just blew my mind how recent it was. Next, the author covered the more modern extinctions and how the migration of Homo sapiens aligns with the extinction of several species, and how to current activities may lead to the next mass extinction without a random catastrophe.
Now, onto the subject of making a species come back from extinction. As it may not be such a surprise with the dire wolves, we have not brought a species from extinction. As far as I know, science has not gone that far yet. The dire wolves are just grey wolves with some genes edited, but they are very cute, nonetheless. Even if they did come back from extinction, the species would still be considered functionally extinct, since the scientists are not trying to breed the wolves together. Also, as was brought up with Jurassic Park, I’m not sure that we should consider bringing species back, as cool as it would be. Evolution has continued without the existence of these species, so there would be no natural protections, unless you consider humans poaching them, which, I believe, would inevitably happen. Any de-extinct species would, in my opinion, be a glorified invasive species. In this example, wolves are considered top predators in their environment and would probably have no natural failsafe to keep the ecosystems aligned. I personally believe that we should focus on keeping the species that are still alive alive, rather than trying to create new species for us to protect or protect against. (But that might be none of my business.)
