Extinct Animals That Might Come Back. Advances in science, specifically biotechnology, could enable scientists to bring some of these animals 'back' from extinction, and there are a few already on the list. We have grown up listening to the idiom “as dead as dodo” because probably back then there were no hopes, no chances for its coming back.

But using genetic engineering to bring back extinct animals might be considered reasonable in some circumstances. But it depends on the species and the context. Animals can be brought back to healthy numbers, and can continue to live for generations to come as part of earth’s vast ecosystem.

While it may sound like a cool idea to bring animals like the moa and the tasmanian tiger back from extinction, new research shows this would come at the cost of other already threatened species.

Planet earth teems with life and includes thousands of species of vertebrate animals (mammals, reptiles, fish, and birds); We're kinda glad we don't have to face off against them. One way to do that might be to bring back neanderthals through genetic. They have gone as far as successfully creating an embryo.
