NASA’n\u0131n Curiosity gezgini, Mars’\u0131n Gale Krateri arazisinde bir dizi alt\u0131gen \u00e7amur \u00e7atla\u011f\u0131 ke\u015ffetti. Bu belirgin desenler, K\u0131z\u0131l Gezegen’in bir zamanlar \u00e7ok daha s\u0131cak ve daha \u0131slak oldu\u011funu ve milyonlarca y\u0131l boyunca \u0131slak ve kuru d\u00f6nemlerden ge\u00e7ti\u011fini g\u00f6steriyor.<\/p>\n\n
Bu ko\u015fullar\u0131n ya\u015fam\u0131n ortaya \u00e7\u0131kmas\u0131 i\u00e7in ideal oldu\u011fu teorile\u015ftirilmi\u015ftir. Kuruyan \u00e7amur \u00fczerinde yeni \u00e7atlaklar olu\u015ftu\u011funda, genellikle T \u015feklindedirler. Bununla birlikte, su topra\u011f\u0131 d\u00fczenli olarak yeniden nemlendirirse, k\u00f6\u015feleri yumu\u015fayarak Y \u015feklindeki kav\u015faklara d\u00f6n\u00fc\u015f\u00fcr.

S\u0131v\u0131 suyun Mars’ta birikmesi ve akmas\u0131 i\u00e7in gezegenin bug\u00fcn oldu\u011fundan \u00e7ok daha s\u0131cak olmas\u0131 gerekiyordu. \u00d6nceki hipotezler, volkanik patlamalar gibi tek seferlik olaylar\u0131n k\u0131sa \u0131s\u0131nma d\u00f6nemlerine neden olabilece\u011fini \u00f6ne s\u00fcrd\u00fc. Bununla birlikte, alt\u0131gen \u015fekiller, Mars’\u0131n \u0131l\u0131k ikliminin binlerce ila milyonlarca y\u0131l s\u00fcrd\u00fc\u011f\u00fc arg\u00fcman\u0131n\u0131 g\u00fc\u00e7lendiriyor.<\/p>\n\n
Mars’taki tekrarlayan \u0131slak-kuru d\u00f6ng\u00fcleri, bile\u015fikleri biyomolek\u00fcllere d\u00f6n\u00fc\u015ft\u00fcren kimyasal reaksiyonlar i\u00e7in ko\u015fullar yaratm\u0131\u015f olabilir. \u00d6zellikle bu reaksiyonlar, DNA’n\u0131n \u00f6nemli bir bile\u015feni olan n\u00fckleik asitler \u00fcretebilir. Islak-kuru d\u00f6ng\u00fcleri tek ba\u015f\u0131na ya\u015fam\u0131 olu\u015fturamazken, ona yol a\u00e7an molek\u00fcler evrim i\u00e7in gerekli olabilirler.<\/p>\n\n

Mars’\u0131 incelemek, D\u00fcnya’daki ya\u015fam\u0131n ortaya \u00e7\u0131k\u0131\u015f\u0131n\u0131 anlamam\u0131za yard\u0131mc\u0131 olabilir.
