Normal do\u011fum mu sezaryen do\u011fum mu? diye d\u00fc\u015f\u00fcnen annelerin bir nebze de olsa sorular\u0131na cevap olacak makalemiz umuyoruz ki size yard\u0131mc\u0131 olur. Avusturya ve Amerikal\u0131 bir ara\u015ft\u0131rmac\u0131 ekibi bebeklerde sezaryenle do\u011fum yapan annelerin neden oldu\u011fu evrimsel bir de\u011fi\u015fimi tespit etti. Bilim adamlar\u0131n\u0131n bulgusuna g\u00f6re bebeklerin kafalar\u0131 b\u00fcy\u00fcyor ancak annelerin do\u011fum kanal\u0131 sabit kal\u0131yor. Ara\u015ft\u0131rmac\u0131lar Ulusal Bilimler Akademisi dergisinde bu bulgular\u0131n\u0131 yay\u0131nlad\u0131lar.<\/p>\n

E\u011fer bir bebe\u011fin kafas\u0131 ge\u00e7mek i\u00e7in \u00e7ok b\u00fcy\u00fckse (fetopelvik uyumsuzluk) cerrah yard\u0131m\u0131yla annenin karn\u0131n\u0131n alt k\u0131sm\u0131na yap\u0131lan k\u00fc\u00e7\u00fck bir kesikle bebek do\u011furuluyor.

Peki sezaryenle do\u011furulan bebe\u011fin sonucu ne oluyor? Ara\u015ft\u0131rmac\u0131lara g\u00f6re bu bir sonraki nesildeki bebeklerin daha da b\u00fcy\u00fck bir kafaya sahip olmas\u0131yla neticeleniyor. Mant\u0131ken kafas\u0131 b\u00fcy\u00fck olan bebek do\u011fum s\u0131ras\u0131nda \u00f6lmek yerine ya\u015famaya devam ederse ve bu insanl\u0131k tarihinde uzunca bir s\u00fcre ger\u00e7ekle\u015firse, insanlar b\u00fcy\u00fck kafal\u0131 bebekler do\u011furan genleri ta\u015f\u0131yacak.<\/p>\n
