Modern insan\u0131n atalar\u0131ndan biri olan Homo erectus, yakla\u015f\u0131k iki milyon y\u0131l \u00f6nce Afrika’dan di\u011fer co\u011frafyalara yay\u0131lan t\u00fcrlerden biriydi.

Bu konuda belki de tek istisna, Endonezya’n\u0131n Java Adas\u0131’ndaki Ngandong isimli b\u00f6lgeydi. Bu b\u00f6lgede yap\u0131lan kaz\u0131 \u00e7al\u0131\u015fmalar\u0131 s\u0131ras\u0131nda Homo erectus t\u00fcr\u00fcne ait fosil kal\u0131nt\u0131lar\u0131na rastlanm\u0131\u015ft\u0131. Ancak bu fosiller \u00fczerinde \u00e7al\u0131\u015fma yapan biliminsanlar\u0131, ya\u015f tayinini net bir bi\u00e7imde yapam\u0131yorlard\u0131. Bu durumun temel nedenleri, bu canl\u0131lara ait fosillerin bulunduklar\u0131 b\u00f6lgenin topra\u011f\u0131ndaki tabakala\u015fman\u0131n nas\u0131l ger\u00e7ekle\u015fti\u011finin bilinememesi ve bu buluntular\u0131n fosille\u015fmeye ba\u015flad\u0131klar\u0131 yere dair net kay\u0131tlar\u0131n olmamas\u0131yd\u0131.<\/p>\n

Nature dergisinde yay\u0131nlanan \u00e7al\u0131\u015fmada yer alan Macquarie \u00dcniversitesi ve Endonezya’daki Bandung Teknoloji Enstit\u00fcs\u00fc’nden biliminsanlar\u0131 Homo erectus’un d\u00fcnya \u00fczerindeki son varl\u0131\u011f\u0131n\u0131n 108.000 y\u0131l ile 117.000 y\u0131l \u00f6ncesine dayand\u0131\u011f\u0131n\u0131 raporlad\u0131.<\/p>\n

Ara\u015ft\u0131rmac\u0131lar, 12 adet Homo erectus kafatas\u0131 ile iki adet bacak kemi\u011fi \u00fczerinde yapt\u0131klar\u0131 ya\u015f tayin \u00e7al\u0131\u015fmas\u0131na ek olarak, b\u00f6lgeden edindikleri toprak \u00f6rneklerini de inceledi. B\u00f6ylece bu eski insan\u0131n d\u00fcnya \u00fczerindeki son zamanlar\u0131n\u0131n ne kadar eskiye dayand\u0131\u011f\u0131na dair daha kesin veriler elde edilebildi.<\/p>\n

Iowa’da antropoloji alan\u0131nda \u00e7al\u0131\u015fma y\u00fcr\u00fcten Profes\u00f6r Russell Ciochon, “Bu \u00e7al\u0131\u015fma, Homo erectus’un d\u00fcnyan\u0131n herhangi bir yerindeki en son g\u00f6r\u00fcn\u00fcm\u00fc. Homo erectus’un bundan sonra ba\u015fka herhangi bir yerde ya\u015fad\u0131\u011f\u0131na dair hi\u00e7bir kan\u0131t\u0131m\u0131z yok” a\u00e7\u0131klamalar\u0131nda bulundu.<\/p>\n

Konuya ili\u015fkin olarak daha \u00f6nce yap\u0131lan \u00e7al\u0131\u015fmalar Homo erectus’un Afrika’dan \u00e7\u0131karak Endonezya’da bulunan tak\u0131madalara do\u011fru y\u00f6neldi\u011fini ve yakla\u015f\u0131k olarak 1.6 milyon y\u0131l \u00f6nce Java Adas\u0131’na ula\u015ft\u0131\u011f\u0131n\u0131 g\u00f6stermekteydi.
