\u00c7inli paleontologlar, \u00c7in’in kuzeydo\u011fusunda bulunan bir fosilden soyu t\u00fckenmi\u015f ve derinlemesine farkl\u0131 bir kaplan soyu tespit ederek, kaplanlar\u0131n daha karma\u015f\u0131k bir evrimsel ge\u00e7mi\u015fine dair bir resim ortaya \u00e7\u0131kard\u0131.<\/b><\/p>\n
Wuhan merkezli \u00c7in Yerbilimleri \u00dcniversitesi\u2019nden ara\u015ft\u0131rmac\u0131lar, antik soyun yakla\u015f\u0131k 268.000 y\u0131l \u00f6nce modern kaplanlardan ayr\u0131\u015ft\u0131\u011f\u0131n\u0131 buldular.<\/p>\n
Bu, yakla\u015f\u0131k 125.000 y\u0131l \u00f6nce ya\u015fayan modern kaplanlar\u0131n anne soyundan atalar\u0131n\u0131n bilinen ya\u015f\u0131n\u0131n iki kat\u0131ndan fazla.<\/p>\n
\u00c7in\u2019in kuzeydo\u011fusunda yer alan Jilin eyaletindeki Da\u2019an karst ma\u011faras\u0131nda bir kaplan \u00e7ene kemi\u011fi bulundu. Ma\u011farada s\u0131rtlan fosilleri de bulundu. Da\u2019an karst ma\u011faras\u0131, kaplanlar\u0131n tarihsel da\u011f\u0131l\u0131m aral\u0131\u011f\u0131nda ve Amur kaplanlar\u0131n\u0131n mevcut ya\u015fam alanlar\u0131 dahilinde yer al\u0131yor.<\/p>\n
Kal\u0131nt\u0131 DNA\u2019s\u0131 \u00fczerinde yap\u0131lan analiz, \u00e7ene kemi\u011finin s\u0131rtlanlara de\u011fil, soyu bilinmeyen bir kaplana ait oldu\u011funu g\u00f6sterdi. Proceedings of The Royal Society B dergisinde yak\u0131n zamanda yay\u0131nlanan ara\u015ft\u0131rmaya g\u00f6re, bu kaplan\u0131n tarihi 43.500 y\u0131ldan daha eskiye dayan\u0131yor.<\/p>\n
Ara\u015ft\u0131rmac\u0131lar, eski kaplan\u0131n anne ve baba soyuna ait tarihini g\u00f6stermek i\u00e7in fosilin hem mitokondriyal hem de n\u00fckleer genom verilerini kurtarmay\u0131 ba\u015fard\u0131.<\/p>\n
Ara\u015ft\u0131rmac\u0131lar, yak\u0131n b\u00f6lgelerde ma\u011fara aslanlar\u0131n\u0131n fosillerinin de kaydedildi\u011fini s\u00f6yledi. Lakin bu ma\u011fara aslanlar\u0131n\u0131n, modern kaplanlar\u0131n uzak bir kuzeni olan yeni tan\u0131mlanan y\u0131rt\u0131c\u0131 ile bir arada var olup olmad\u0131\u011f\u0131 hen\u00fcz net de\u011fil.<\/p>\n
Ancak, ara\u015ft\u0131rmaya g\u00f6re, olduk\u00e7a farkl\u0131 ya\u015fam alanlar\u0131n\u0131 tercih eden iki \u00fcst y\u0131rt\u0131c\u0131 hayvan aras\u0131ndaki co\u011frafi \u00f6rt\u00fc\u015fme hala olas\u0131 g\u00f6r\u00fcnm\u00fcyor.<\/p>\n
Ara\u015ft\u0131rmac\u0131lara g\u00f6re, \u00e7al\u0131\u015fma, kaplanlar\u0131n son yay\u0131l\u0131m\u0131ndan \u00f6nceki evrimsel tarihine yeni bir bak\u0131\u015f a\u00e7\u0131s\u0131 getiriyor ve \u00c7in\u2019deki fosil kaplanlar\u0131n antik bir geneti\u011fe sahip oldu\u011funu vurguluyor.<\/p>\n","protected":false},"excerpt":{"rendered":"
