An extinct animal has been brought back to life for the first time after being cloned from frozen tissue.
The Pyrenean ibex, a form of wild mountain goat, was officially declared extinct in 2000 when the last-known animal of its kind was found dead in northern Spain.
Shortly before its death, scientists preserved skin samples of the goat, a subspecies of the Spanish ibex that live in mountain ranges across the country, in liquid nitrogen.
Using DNA taken from these skin samples, the scientists were able to replace the genetic material in eggs from domestic goats, to clone a female Pyrenean ibex, or bucardo as they are known. It is the first time an extinct animal has been cloned.
Sadly, the newborn ibex kid died shortly after birth due to physical defects in its lungs. Other cloned animals, including sheep, have been born with similar lung defects.
But the breakthrough has raised hopes that it will be possible to save endangered and newly extinct species by resurrecting them from frozen tissue.
It has also increased the possibility that it will one day be possible to reproduce long-dead species such as woolly mammoths and even dinosaurs.

In many ways we as a species, a member of the animal kingdom, have overstepped our bounds.
We could restore the balance to many ecosystems that we have irresponsibly altered.
As for those animals we keep in captivity, there is a lot to be learned.
For starters... what did they look like and how did they behave etc.

There is a reason animals become extinct.
In the process of natural selection does it seem fit that a failed species should "suddenly" be foisted back into a life-cycle that it previously failed?
Doesn't make good sense to me. What has science to gain by reanimating a dead species.....to determine why it failed?
Sounds like running in circles to me.
