بقايا عمرها 122 ألف سنة.. ما سر عزوف القدماء عن “الربع الخالي”؟

Back

ما يعرفه ريفو عن الخبر

  • كشف فريق بحثي دولي عن سبب عزوف الإنسان القديم عن استيطان مناطق واسعة في شبه الجزيرة العربية رغم توفر المياه العذبة فيها.
  • أثبتت الدراسة أن غياب الصخور القابلة للتشكيل وصناعة الأدوات الحجرية حال دون استقرار البشر في تلك المناطق.
  • أظهرت النتائج أن المناطق التي تفتقر للأحجار المناسبة أو تفتقر للمياه لم تكن صالحة للاستيطان البشري خلال فترات جيولوجية سابقة.
  • أكدت الدراسة أن المسافات الطويلة بين مصادر الصخور الجيدة ومواقع البحيرات جعلت من الصعب على الإنسان القديم تجديد مخزونه من الأدوات.

تكشف دراسة نشرتها دورية "نيتشر" أن توافر المياه لم يكن وحده كافيا لاستقرار البشر القدماء في صحراء "الربع الخالي" إذ احتاجوا أيضا إلى أحجار مناسبة لصناعة أدواتهم.
