Develer, do\u011fan\u0131n <\/span><\/span>\u00e7etin \u015fartlar\u0131na meydan okuyan harika birer canl\u0131d\u0131r. \u00c7\u00f6l\u00fcn kavurucu s\u0131caklar\u0131nda, su ve yiyecek k\u0131tl\u0131\u011f\u0131nda hayatta kalabilmeleri onlar\u0131n ne kadar dayan\u0131kl\u0131 ve adaptasyon yetene\u011fi y\u00fcksek canl\u0131lar oldu\u011funu g\u00f6zler \u00f6n\u00fcne seriyor. Fakat develer, yaln\u0131zca dayan\u0131kl\u0131l\u0131klar\u0131yla de\u011fil, ayn\u0131 zamanda biyolojik a\u00e7\u0131dan \u015fa\u015f\u0131rt\u0131c\u0131 \u00f6zellikleriyle de hayranl\u0131k uyand\u0131r\u0131r.
\n\u00d6ncelikle, devenin su t\u00fcketimi konusunda s\u0131ra d\u0131\u015f\u0131 bir yetene\u011fi vard\u0131r. Hem tatl\u0131 hem de tuzlu suyu i\u00e7ebilen bu hayvan, gerekti\u011finde \u00d6l\u00fcdeniz\u2019in tuzlu suyunu bile t\u00fcketebilir. Peki, bu nas\u0131l m\u00fcmk\u00fcn oluyor? Devenin b\u00f6brekleri, suyu tuzdan ar\u0131nd\u0131rarak i\u00e7ilebilir hale getiriyor. Bu ola\u011fan\u00fcst\u00fc mekanizma, suyun en k\u0131ymetli kaynak oldu\u011fu \u00e7\u00f6l gibi b\u00f6lgelerde devenin en b\u00fcy\u00fck avantaj\u0131d\u0131r. \u00dcstelik devenin men\u00fcs\u00fc de olduk\u00e7a s\u0131rad\u0131\u015f\u0131. Sert ve dikenli bitkileri rahatl\u0131kla t\u00fcketebilir. T\u00fck\u00fcr\u00fc\u011f\u00fcnde bulunan \u00f6zel bir bile\u015fen, dikenleri adeta asit gibi eriterek mide ve ba\u011f\u0131rsaklar\u0131na zarar vermesini \u00f6nler. Bir di\u011fer ilgin\u00e7 \u00f6zellik ise devenin g\u00f6z kapaklar\u0131d\u0131r. Deve, iki farkl\u0131 g\u00f6z kapa\u011f\u0131na sahiptir: biri ince ve \u015feffaf, di\u011feri ise kal\u0131n ve etlidir. \u00c7\u00f6l r\u00fczgarlar\u0131n\u0131n kumla dolup ta\u015ft\u0131\u011f\u0131 anlarda, \u015feffaf g\u00f6z kapa\u011f\u0131n\u0131 kapatarak kum f\u0131rt\u0131nas\u0131nda bile g\u00f6r\u00fc\u015f\u00fcn\u00fc kaybetmez. Bu, do\u011fan\u0131n hayatta kalma sanat\u0131nda devenin ustal\u0131\u011f\u0131n\u0131 bir kez daha g\u00f6steriyor.
\nDeveler ayr\u0131ca termoreg\u00fclasyon, yani v\u00fccut \u0131s\u0131s\u0131n\u0131 ayarlama konusunda ustad\u0131r. G\u00fcn\u00fcn en s\u0131cak saatlerinde v\u00fccut \u0131s\u0131s\u0131n\u0131 d\u00fc\u015f\u00fcrerek \u00e7\u00f6l s\u0131ca\u011f\u0131na diren\u00e7 g\u00f6sterirken, gecenin so\u011fuk saatlerinde \u0131s\u0131lar\u0131n\u0131 art\u0131rabilirler. Bu \u00f6zellik, \u00e7\u00f6l gibi a\u015f\u0131r\u0131 s\u0131cakl\u0131k farklar\u0131n\u0131n ya\u015fand\u0131\u011f\u0131 b\u00f6lgelerde hayatta kalmalar\u0131n\u0131 sa\u011flar.
\nDo\u011fa, deveyi adeta hayatta kalma sanat\u00e7\u0131s\u0131 olarak tasarlam\u0131\u015f. Onlar\u0131n bu s\u0131ra d\u0131\u015f\u0131 \u00f6zelliklerini \u00f6\u011frenmek, yaln\u0131zca biyolojik bir hayranl\u0131k yaratmakla kalm\u0131yor, ayn\u0131 zamanda do\u011fan\u0131n ne denli m\u00fckemmel i\u015fledi\u011fini de bir kez daha g\u00f6zler \u00f6n\u00fcne seriyor. Deve, dayan\u0131kl\u0131l\u0131\u011f\u0131n, adaptasyonun ve do\u011fan\u0131n yarat\u0131c\u0131l\u0131\u011f\u0131n\u0131n ya\u015fayan bir simgesi. Belki de bu y\u00fczden, deve dendi\u011finde yaln\u0131zca bir \u00e7\u00f6l hayvan\u0131n\u0131 de\u011fil, ayn\u0131 zamanda do\u011fan\u0131n bize sundu\u011fu bir mucizeyi g\u00f6rmeliyiz.<\/span><\/span><\/p>\n
