عبر الجزيرة العربية.. المياه الجوفية قادت الإنسان القديم في رحلته إلى خارج أفريقيا

ما يعرفه ريفو عن الخبر

  • لعبت المياه الجوفية والينابيع دورا أساسيا في توفير الملاذات المائية للإنسان القديم أثناء رحلة الهجرة من شرق أفريقيا.
  • أظهرت الدراسة أن عبور باب المندب نحو الجزيرة العربية كان أكثر قابلية للتفسير مائيا من المسارات التقليدية الأخرى.
  • وفرت الخزانات الجوفية الضخمة في الجزيرة العربية سلسلة من الينابيع والواحات التي سمحت باستمرار الحركة خلال فترات الجفاف الطويلة.
  • كشفت الأدلة الأثرية عن وجود أدوات حجرية كثيفة في مواقع مرتبطة بالمياه الجوفية عبر مسارات محددة في السعودية والأردن.

كشفت دراسة أن المياه الجوفية ربما ساعدت الإنسان منتصب القامة على مغادرة أفريقيا قبل نحو 1.9 مليون سنة. وللتوصل إلى تلك النتيجة، جمع العلماء بيانات الأحافير والأدوات الحجرية مع مصادر المياه القديمة.
