Almanya’daki Max Planck Evrimsel Antropoloji Enstit\u00fcs\u00fc\u2019nden Svante P\u00e4\u00e4bo liderli\u011findeki bir ekip, 2018\u2019in A\u011fustos ay\u0131nda, <\/span>Nature<\/span><\/i> dergisinde yay\u0131mlanan bir makaleyle Denny\u2019nin do\u011fumunu m\u00fcjdeledi. Kendisi, bilinen ilk annesi Neandertal & babas\u0131 Denisova birey. S\u0131ras\u0131yla Avrasya\u2019n\u0131n bat\u0131s\u0131nde ve do\u011fusunda yerle\u015fik bu iki insans\u0131 grubu \u00f6yle g\u00f6r\u00fcn\u00fcyor ki Rusya\u2019da, Altay Da\u011flar\u0131\u2019n\u0131n Sibirya\u2019ya bakan y\u00fcz\u00fc dolaylar\u0131nda \u00e7iftle\u015fmi\u015f. Nitekim Denny\u2019nin bulundu\u011fu mevkii de tam bu b\u00f6lgede, Denisova Ma\u011faras\u0131 ad\u0131 verilen, i\u00e7inde hem Neandertallara hem Denisovalara ait kal\u0131nt\u0131lara rastlanan bir yerde. Her iki grubun modern insanlarla da \u00e7iftle\u015fti\u011fi DNA bulgular\u0131yla ve \u00e7e\u015fitli kemik kal\u0131nt\u0131lar\u0131yla ortaya kondu. Fakat bir Denisova-Neandertal yavrusuna daha \u00f6nce hi\u00e7 rastlanmam\u0131\u015ft\u0131. \u00dcstelik de birinci nesil bir yavru, kemik kal\u0131nl\u0131\u011f\u0131na bak\u0131l\u0131rsa en az 13\u2019\u00fcnde bir k\u0131z \u00e7ocu\u011fu!<\/span><\/p>\n

Asl\u0131nda Denny\u2019nin varl\u0131\u011f\u0131 \u00e7oktand\u0131r biliniyor. Kendisiyle ilgili ara\u015ft\u0131rmalar\u0131n sonu\u00e7lar\u0131 ilk kez 2016\u2019da, <\/span>Scientific Reports<\/span><\/i> dergisinde sunulmu\u015f, \u00f6l\u00e7\u00fcm tekniklerinin o zamanki s\u0131n\u0131rlar\u0131 \u00e7er\u00e7evesinde ya\u015f\u0131n\u0131n 50.000\u2019den fazla oldu\u011fu s\u00f6ylenmi\u015fti. Aradan ge\u00e7en iki y\u0131lda ekip analizlerini derinle\u015ftirdi; ayn\u0131 ma\u011faradan Neandertal ve Denisova \u00f6rnekleriyle kar\u015f\u0131la\u015ft\u0131rmalar yapt\u0131 ve nihayet kesin sonuca ula\u015ft\u0131: Denny\u2019ye ait 50.000 ya\u015f\u0131ndaki uzun kemik par\u00e7as\u0131ndan elde edilen DNA %40 kadar Neandertal ve %40 kadar Denisova \u00f6zellikleri sergiliyordu. Dahas\u0131 Denny\u2019nin anne ve babas\u0131n\u0131n bir Neandertal-Denisova karmas\u0131 pop\u00fclasyona ait olmad\u0131\u011f\u0131, basbaya\u011f\u0131 kendi ayr\u0131 genetik \u00f6zelliklerini koruyan iki ayr\u0131 insans\u0131n\u0131n \u00e7iftle\u015fmesinin s\u00f6z konusu oldu\u011fu saptand\u0131. Ha, bu birle\u015fme Denny\u2019nin Neandertal annesinin r\u0131zas\u0131yla m\u0131 ger\u00e7ekle\u015fti yoksa kar\u015f\u0131l\u0131kl\u0131 mutabakat yok muydu, bu ayr\u0131 bir merak konusu. Ancak \u015fayet Denny varsa, onun gibi ba\u015fkalar\u0131 da vard\u0131r diye d\u00fc\u015f\u00fcn\u00fclebilir\u2026 Yaln\u0131z iki grubun karmas\u0131 bir pop\u00fclasyona hen\u00fcz rastlanmam\u0131\u015f, yani Neandertallar\u0131n hep Neandertal, Denisovalar\u0131n da hep Denisova kalm\u0131\u015f olmas\u0131, melezlerin topluluk i\u00e7inde \u00f6ne \u00e7\u0131kmas\u0131n\u0131 engelleyecek dezavantajlara sahip olarak do\u011fduklar\u0131n\u0131 d\u00fc\u015f\u00fcnd\u00fcr\u00fcyor. Muhtemelen bu sorular zamanla yan\u0131t bulacak, hatta belki kimi yan\u0131tlar de\u011fi\u015fecek ve yeniden \u015fekillenecek. Ama Denny\u2019nin insans\u0131lar tarihinin en ilgin\u00e7 genomuna sahip oldu\u011fu ger\u00e7e\u011fi herhalde hi\u00e7 de\u011fi\u015fmeyecek!<\/span><\/p>\n
