Darwin, bu ke\u015ffin \u00f6nemini fark ederek b\u00f6ylesine k\u00fc\u00e7\u00fck ve izole bir adada bu kadar b\u00fcy\u00fck bir kara memelisinin al\u0131\u015f\u0131lmad\u0131k oldu\u011funu belirtti.<\/p>\n\n
E\u015fsiz do\u011fas\u0131na ra\u011fmen, Falkland Adas\u0131 kurdu bir\u00e7ok zorlukla kar\u015f\u0131la\u015ft\u0131. Artan insan n\u00fcfusu ve koyunlar\u0131n getirilmesi onun azalmas\u0131na yol a\u00e7t\u0131. Darwin, t\u00fcr\u00fcn nihai olarak yok olaca\u011f\u0131n\u0131 tahmin etti ve bu ne yaz\u0131k ki 1876’da ger\u00e7ekle\u015fti.<\/p>\n\n
Darwin’in zaman\u0131ndan bu yana, bilim insanlar\u0131 Falkland Adas\u0131 kurdunun k\u00f6kenlerini ve evrimini ara\u015ft\u0131rd\u0131. Tarihi hakk\u0131nda bilgi edinmek i\u00e7in ara\u015ft\u0131rmac\u0131lar, Darwin’in bizzat toplad\u0131\u011f\u0131 da dahil olmak \u00fczere m\u00fcze \u00f6rneklerinden DNA \u00e7\u0131kard\u0131.<\/p>\n\n

Bu analiz, Falkland Adas\u0131 kurdunun en yak\u0131n akrabalar\u0131ndan yakla\u015f\u0131k 70.000 y\u0131l \u00f6nce, son buz \u00e7a\u011f\u0131yla ayn\u0131 zamana denk gelecek \u015fekilde ayr\u0131ld\u0131\u011f\u0131n\u0131 ortaya \u00e7\u0131kard\u0131.<\/p>\n\n

Falkland Adas\u0131 kurdu, adalara vard\u0131ktan sonra ortam\u0131na uyum sa\u011flad\u0131. Ba\u015fka yerli kara memelisi olmad\u0131\u011f\u0131 i\u00e7in muhtemelen penguenler, kazlar ve deniz memelileriyle besleniyordu.<\/p>\n\n
Filogenetik analiz, Falkland Adas\u0131 kurdu ile yeleli kurt aras\u0131nda beklenmedik bir ili\u015fki ortaya \u00e7\u0131kard\u0131. Bu iki t\u00fcr ortak bir atay\u0131 payla\u015f\u0131yor, ancak 6 milyon y\u0131ldan fazla bir s\u00fcre \u00f6nce ayr\u0131ld\u0131. Bu bulgu, G\u00fcney Amerika’daki k\u00f6peklerin evrimsel tarihi hakk\u0131nda sorular\u0131 g\u00fcndeme getiriyor.<\/p>\n\n
DNA analizi de\u011ferli bilgiler sa\u011flasa da yeni gizemler de ortaya \u00e7\u0131kard\u0131. Falkland Adas\u0131 kurdu ve yeleli kurdun ayr\u0131ld\u0131\u011f\u0131 zamana ait hen\u00fcz hi\u00e7bir k\u00f6pek fosili bulunamad\u0131.

Darwin ve di\u011ferleri taraf\u0131ndan toplanan m\u00fcze \u00f6rnekleri, Falkland Adas\u0131 kurdunun tarihini ayd\u0131nlatmada \u00e7ok \u00f6nemli bir rol oynad\u0131. Bu \u00f6rnekler, DNA analizi i\u00e7in de\u011ferli genetik materyal sa\u011fl\u0131yor ve bilim insanlar\u0131n\u0131n t\u00fcr\u00fcn evrimsel ge\u00e7mi\u015fini yeniden yap\u0131land\u0131rmas\u0131na olanak tan\u0131yor.<\/p>\n\n
Falkland Adas\u0131 kurdunun hikayesi, bilimsel sorgulaman\u0131n g\u00fcc\u00fcne bir kan\u0131tt\u0131r.
