IF we have the capability to sustain them comfortably for the natural lifespan.
it would help scientists
It would be super cool to revive like mammoths, and megladons.
Some, yes. Any species that humans have hunted to extinction should be a candidate. If the ecological niche that animal left behind has not yet been filled by another species, we should seriously consider reintroducing them. Also we need dinosaurs, because reasons.
But it would have to depend on the species
i think so but still it would drastically change our ecosystems and the climate would be very different.
Because, our life would be different. What if Dodo's were actually dangerous, that's probably why hunters killed them ALL.
