Maybe I’m dumb but I thought extinct meant there were no more left. Not a single one. Totally gone. And endangered was the word for if their number were dangerously low but not zero. So how can something come back after 2 decades of extinction? Genuinely asking, someone educate me lol
Not a stupid question! The answer is kinda but not really. For example, horses and donkeys are separate animals but they can be bred to create mules. So if donkeys went extinct but we had some frozen sperm, we could theoretically impregnate a horse with it. But it wouldn’t bring back donkeys - it would create a mule. And mules are infertile bcos we’re not great at playing God
Then past that we currently don’t know how to successfully grow much of anything purely from a Petri dish - we’d need to implant it in something in an animal version of IVF, which would be extremely expensive and complicated and not super likely to work and potentially could be considered animal cruelty
They’re currently classified as vulnerable and decreasing, so they’ll probably get their endangered classification back soon. But yeah, conservation efforts tend to go to the most critical needs. So if one species is no longer endangered, we shift gears to helping a species that is still critically endangered. We don’t have unlimited funds so we have to triage. It’s unfortunate, but it’s also the most effective way to slow/stop extinctions
