However, the success rate has been very low:** [|**Dolly**] **was born after 276 failed attempts; 70 calves have been created from 9,000 attempts and one third of them died young;** [|**Prometea**] **took 328 attempts, and, more recently,** [|**Paris Texas**] **was created after 400 attempts. Notably, although the first clones were frogs, no adult cloned frog has yet been produced from a somatic adult nucleus donor cell. Human cloning is the creation of a** [|**genetically**] **identical copy of an existing, or previously existing** [|**human**] **or growing cloned** [|**tissue**] **from that individual. The term is generally used to refer to //artificial// human cloning; human clones in the form of** [|**identical twins**] **are commonplace, with their cloning occurring during the natural process of reproduction.

 * __//Cloning//__ is the process of creating an identical copy of an original. A //clone// in the** [|**biological**] **sense, therefore, is a single** [|**cell**] **(like** [|**bacteria**]**,** [|**lymphocytes**] **etc.) or multi-cellular** [|**organism**] **that is** [|**genetically**] **identical to another living organism. Sometimes this can refer to "natural" clones made either when an organism** [|**reproduces asexually**] **or when two genetically identical individuals are produced by accident (as with** [|**identical twins**]**), but in common parlance the clone is an identical copy by some conscious design. Also see** [|**clone (genetics)**]**. The term //clone// is derived from //κλων//, the** [|**Greek**] **word for "twig". In** [|**horticulture**]**, the spelling //clon// was used until the twentieth century; the final //e// came into use to indicate the vowel is a "long o" instead of a "short o". Since the term entered the popular lexicon in a more general context, the spelling //clone// has been used exclusively.
