The Pyrenean ibex (''Capra pyrenaica pyrenaica''), Spanish common name ''bucardo'', was one of the four subspecies of the Spanish ibex or Iberian wild goat, a species endemic to the Iberian Peninsula. Pyrenean ibex were most common in the Cantabrian Mountains, Southern France, and the northern Pyrenees. This species was common during the Holocene and Upper Pleistocene, during which their morphology, primarily some skulls, of the Pyrenean ibex was found to be larger than other ''Capra'' subspecies in southwestern Europe from the same time. In January 2000, the Pyrenean ibex became extinct, but scientists have attempted to clone them using DNA from one of the last females; one such clone died seven minutes after being born. Other subspecies survived: the western Spanish or gredos ibex and the southeastern Spanish or beceite ibex, while the Portuguese ibex had already become extinct. Since the last of the Pyrenean ibex went extinct before scientists could adequately analyze them, the taxonomy of this particular subspecies is controversial. ==History== Multiple theories are given regarding the evolution and historical migration of ''C. pyrenaica'' into the Iberian peninsula, and the relationship between the different subspecies. One possibility is that ''C. pyrenaica'' evolved from an ancestor related to ''C. caucasica'' from the Middle East, at the beginning of the last glacial period (120-80 ky). ''C. pyrenaica'' probably moved from the northern Alps through southern France into the Pyrenees area at the beginning of Magdalenian period about 18 kya. If this is the case, then ''C. caucasica praepyrenaica'' may have been more different from the other three ibex species that lived in the Iberian peninsula than scientists currently know. For example, this would mean that the ''C. pyrenaica'' (possible migration 18ky) and ''C. ibex'' (300 ky earlier migration) would have evolved from different ancestors and been morphologically more different from their separate genes.〔 It is known that all four subspecies lived together in the Upper Pleistocene time, but scientists are unsure of how much genetic exchange could have occurred. The problem with this theory is that genetics suggest that ''C. pyrenaica'' and ''C. ibex'' may have shared a more common origin, possibly ''C. camburgensis''.〔 Many versions of when ''C. pyrenaica'' or ''C. ibex'' first migrated to and evolved in the Iberian peninsula are related. ''C. pyrenaica'' possibly was already living in the Iberian Peninsula when the ibex began to migrate through the Alps. Genetic evidence also supports the theory that multiple ''Capra'' subspecies migrated to the Iberian region around the same time. Hybridization may have been possible, but the results are not conclusive.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Pyrenean ibex」の詳細全文を読む スポンサード リンク
