1994 y\u0131l\u0131nda paleontolog Ron Clarke, G\u00fcney Afrika’daki Sterkfontein ma\u011fara sisteminden gelen bir fosil kutusunda d\u00f6rt k\u00fc\u00e7\u00fck ayak bile\u011fi kemi\u011fi par\u00e7as\u0131 ke\u015ffetti. Bunlar\u0131n erken bir insan atas\u0131ndan geldi\u011fine inanan Clarke, daha fazla kemik arad\u0131 ve sonunda bre\u015f ad\u0131 verilen beton benzeri bir maddeye g\u00f6m\u00fcl\u00fc neredeyse eksiksiz bir iskelet buldu.<\/p>\n\n
Kaz\u0131 s\u00fcreci zahmetli ve zaman al\u0131c\u0131yd\u0131. Clarke ve ekibi, k\u0131r\u0131lgan par\u00e7alar\u0131 ta\u015ftan dikkatlice \u00e7\u0131karmak i\u00e7in i\u011fneler gibi k\u00fc\u00e7\u00fck aletler kulland\u0131lar. “Little Foot” olarak adland\u0131r\u0131lan fosilin t\u00fcm izlerini bulup \u00e7\u0131karmak 2012 y\u0131l\u0131na kadar s\u00fcrd\u00fc.<\/p>\n\n
Little Foot, \u015fimdiye kadar bulunmu\u015f en eksiksiz insan atas\u0131 iskeletlerinden biridir. 1970’lerde Etiyopya’da ke\u015ffedilen \u00fcnl\u00fc erken hominin iskeleti Lucy sadece y\u00fczde 40 oran\u0131nda eksiksizken, Little Foot \u015fa\u015f\u0131rt\u0131c\u0131 bir \u015fekilde y\u00fczde 90 oran\u0131nda eksiksiz ve kafatas\u0131 bile duruyor.<\/p>\n\n
Bu ola\u011fan\u00fcst\u00fc eksiksizlik, ara\u015ft\u0131rmac\u0131lar\u0131n erken homininlerin anatomisi ve davran\u0131\u015flar\u0131 hakk\u0131nda benzeri g\u00f6r\u00fclmemi\u015f bilgiler edinmesine olanak sa\u011flad\u0131. Little Foot’un Lucy’den farkl\u0131 bir Australopithecus t\u00fcr\u00fcn\u00fc temsil etti\u011fi d\u00fc\u015f\u00fcn\u00fcl\u00fcyor ve 3,67 milyon y\u0131l \u00f6ncesine kadar uzanan daha eski bir t\u00fcre ait olabilir.<\/p>\n\n
Little Foot’un tarihlendirilmesi tart\u0131\u015fmalar\u0131n konusu oldu. Baz\u0131 ara\u015ft\u0131rmac\u0131lar, ya\u015f\u0131n\u0131 belirlemek i\u00e7in kullan\u0131lan y\u00f6ntemlerin do\u011frulu\u011funu sorgulad\u0131. Ancak Clarke ve ekibi, Little Foot’un ke\u015ffedilen en eski ve en eksiksiz hominin fosillerinden biri olabilece\u011fini \u00f6ne s\u00fcren bulgular\u0131n\u0131n arkas\u0131nda duruyor.<\/p>\n\n
Little Foot’un ke\u015ffi ayn\u0131 zamanda erken insan evriminin yeri hakk\u0131ndaki tart\u0131\u015fmay\u0131 da yeniden alevlendirdi. Geleneksel olarak Do\u011fu Afrika, insanl\u0131\u011f\u0131n be\u015fi\u011fi olarak g\u00f6r\u00fcl\u00fcyordu. Ancak Little Foot ve G\u00fcney Afrika’daki di\u011fer fosillerin ke\u015ffi, insan evriminin birden fazla yerde meydana gelmi\u015f olabilece\u011fini d\u00fc\u015f\u00fcnd\u00fcr\u00fcyor.<\/p>\n\n
20 y\u0131ll\u0131k kaz\u0131 ve temizlik \u00e7al\u0131\u015fmas\u0131n\u0131n ard\u0131ndan Little Foot, G\u00fcney Afrika’da ilk kez Johannesburg’daki Witwatersrand \u00dcniversitesi Evrimsel \u00c7al\u0131\u015fmalar Enstit\u00fcs\u00fc’ndeki Hominin Kasas\u0131’nda halka a\u00e7\u0131k sergilendi. Little Foot’un tan\u0131t\u0131m\u0131 bilim insanlar\u0131 ve halk aras\u0131nda b\u00fcy\u00fck bir heyecan yaratt\u0131.<\/p>\n\n
\u00d6n\u00fcm\u00fczdeki y\u0131l, Little Foot’u inceleyen ekip, fosil hakk\u0131nda tahminen 25 bilimsel makale yay\u0131nlamay\u0131 bekliyor. Bu makaleler, insan evrimi hakk\u0131ndaki devam eden tart\u0131\u015fmay\u0131 alevlendirecek ve k\u00f6kenlerimiz hakk\u0131nda yeni bilgiler sa\u011flayacakt\u0131r.<\/p>\n\n
Little Foot’un ke\u015ffi, erken homininlere ili\u015fkin anlay\u0131\u015f\u0131m\u0131z\u0131 k\u00f6kten de\u011fi\u015ftirdi. Ola\u011fan\u00fcst\u00fc eksiksizli\u011fi, anatomileri, davran\u0131\u015flar\u0131 ve evrimsel ili\u015fkileri hakk\u0131nda \u00e7ok say\u0131da bilgi sa\u011flad\u0131. Little Foot \u00fczerinde devam eden ara\u015ft\u0131rmalar, insan evrimi ve do\u011fal d\u00fcnyadaki yerimiz hakk\u0131ndaki bilgilerimizi daha da derinle\u015ftirmeyi vaat ediyor.<\/p>","protected":false},"excerpt":{"rendered":"
