  An extinct mountain goat that was once common in the Pyrenees became the first animal to be brought back from extinction.Researchers used frozen DNA to produce a clone,but the newborn kid died within minutes of birth due to breathing difficulties.

  The Pyrenean ibex is a type of mountain goat,which is believed to have died out completely in 2000.Before the death of the last known individual (a 13­year­old female known as Celia),biologists took cells from her skin and ears,which were frozen in liquid nitrogen (氮).An earlier cloning attempt to use the skin cells failed.But the latest attempt involved the creation of 439 cloned embryos (胚胎).Of these cloned embryos,57 were put into the female domestic goats,but only one goat gave birth and the newborn cloned kid died after seven minutes as a result of lung disease.

  Researchers say that other cloned animals,including sheep,have been born with similar lung disease,but they say that overall the experiment was a major step forward in the effort to bring the ibex back to its mountain home.The leading researcher Jose Folch says,"The cloned kid was genetically like the ibex.In species such as the ibex,cloning is the only possibility to avoid its complete disappearance."

The failure to produce a living clone from DNA that was frozen only a decade ago shows the difficulty researchers would face in trying to bring back species that have been extinct for
