Imo the only relevant #species definition for #deextintion is the ecological one. In other contexts this definition is absolutely silly, because it can't distinguish between a #bat and a #bird if they hunt #insects - it defines a species by their ecological #niche.
Under that definition, an elephant with hair is in fact a #mammoth because it's can live in tundra and serve as an umbrella species capable of shaping an entire #ecosystem, serving a unique role in it.
A #dire #wolf is not actually deextinct if it's not serving the ecosystem the way the OG dire wolf used to.
