Is it allowed according to halacha to bring back extinct species? The technology is on its way, and i have seen some discussion in non-Jewish contexts about the ethics of it, and how we might be "playing God".
On the one hand, God originally created these animals. If they went extinct, especially caused by humans, shouldn't we try and fix it? On the other hand, Hashem made the animals go extinct, and we shouldn't mess with that. But back to the first side, if He's giving us the technology, maybe we should use it.
Is this discussed by any contemporary sources, in either a halachic or hashkafic context? If so, is it allowed or not? And, if it is allowed, does it apply only to animals whose extinction was caused by humans (such as a dodo bird), or also things we had nothing to do with (wooly mammoths, dinosaurs)?
