Bringing back species that died out long ago is not impossible. What would happen if we tried it?
Will we one day walk with dinosaurs or mammoths? The idea isn't completely beyond the realms of possibility.
However, as this video from The Verge
points out, it’s not quite how the Jurassic Park films portray it. In
the original story, scientists extracted DNA from a fossil, stitched the
broken pieces together and used it to fertilise the egg of a modern
creature. It would be feasible, except for the fact that dinosaur DNA is
so old, it will have disintegrated beyond repair.
