Je suis toutes choses ma chère :-)
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. [read more]

Just to point you to PZ Myers post on « Jonathan Wells’ weird notions about development« .
Jonathan Wells has been exposed to a little bit of knowledge, just enough for him to regurgitate a few common phrases that are current in the developmental biology literature, and to pretend that he is profound and revolutionary. Nothing could be further from the truth — his title comes straight out of mainstream evo-devo. It’s actually rather funny, since there is a tiny bit of truth in what he says, but what’s true isn’t original with him, and it certainly doesn’t have the implications he thinks.
