De‐Extinction at a Crossroads: Ecology, Ethics, and the Future of Conservation in the Biotech Age

The recent announcement of a genetically engineered organism resembling the extinct dire wolf (Aenocyon dirus) has reignited a media and academic debate over the ecological, ethical, and philosophical implications of de-extinction. Although the revival was later clarified to be a modified grey wolf with a small fraction of the dire wolf DNA, the case illustrates how close biotechnology is to achieving a true de-extinction. While proponents promote such techniques as innovative additional tools for conservation, this paper calls for a more critical examination of their broader implications. Drawing on insights from invasion ecology, rewilding, ethics, and governance, we argue that de-extinction must not be guided by feasibility or commercial appeal alone. Instead, it requires a multidisciplinary framework to be thoroughly understood, responsibly guided, and-if deemed appropriate-accepted. As biotechnological innovations advance and may become widely used, they should be aligned with biodiversity conservation principles to avoid unintended ecological consequences.
