Why can’t we clone extinct animals?
While the science of cloning is still in its infancy, many scientists believe it’s only a matter of time before extinct animals again walk the Earth. To successfully clone an extinct animal,
scientists need to find animal DNA that is almost entirely intact
.
Can we clone endangered animals?

possible to clone animals
and to specifically clone endangered animals. You are right, though, that some of these cloned animals have defects. But we don’t know if these are genetic defects. … Also, once a single animal is cloned, in order for it to be useful in conservation biology it needs to reproduce.
Is cloning extinct animals a good idea?
There are lots of good reasons to bring back extinct animals. All animals perform important
roles
in the ecosystems they live in, so when lost species are returned, so too are the ‘jobs’ they once performed. Woolly mammoths, for example, were gardeners. … It could be the same for other de-extinct animals, too.
