Has any extinct animal been cloned?
A cloned Pyrenean ibex was born on July 30, 2003, in Spain, but died several minutes later due to physical defects in the lungs. This was the first, and so far only, extinct animal to be cloned.
What animal went extinct twice?

Is dinosaur coming back?
The answer is YES. In fact they will return to the face of the earth in 2050. We found a pregnant T. rex fossil and had DNA in it this is rare and this helps scientists take a step closer of animal cloning a Tyrannosaurus rex and other dinosaurs.
Are there any cloned humans?
Despite several highly publicized claims, human cloning still appears to be fiction. There currently is no solid scientific evidence that anyone has cloned human embryos.
When was the first human cloned?
On Dec. 27, 2002, the group announced that the first cloned baby — named Eve — had been born the day before. By 2004, Clonaid claimed to have successfully brought to life 14 human clones.
Will humans go extinct?
The scientific consensus is that there is a relatively low risk of near-term human extinction due to natural causes. The likelihood of human extinction through its own activities, however, is a current area of research and debate.

Est-ce que le clonage est inefficace?
). L’équipe de chercheurs a démontré que, bien que le processus de clonage demeure inefficace, celui-ci est néanmoins possible. Ils ont utilisé 242 oeufs provenant de dons de 16 femmes qui, simultanément, ont donné les cellules à partir desquels les noyaux ont été prélevés pour le clonage.
Qu’est-ce que le clonage de primates?
L’une des difficultés principales rencontrée lors du clonage de primates est la perte de facteurs essentiels aux divisions cellulaires, lorsque le noyau est retiré de l’oeuf. Ces facteurs sont principalement des protéines constitutives d’une structure appelée le centrosome.
Quels sont les avis sur le clonage reproductif?
Cependant, si les avis sont unanimes contre le clonage reproductif, ils sont plus mitigés en ce qui concerne le clonage thérapeutique en raison de l’exceptionnel potentiel thérapeutique de cette technique. Intéressé par ce que vous venez de lire?
Pourquoi les scientifiques craignent-ils le clonage reproductif?
Certains scientifiques craignent que l’annonce de cette réussite, et la publication du protocole de clonage, n’incite des scientifiques peu scrupuleux à se lancer dans des tentatives de clonage reproductif. Actuellement, le clonage humain a été banni dans un grand nombre de pays.
