Eleanor Scerri
Eleanor Scerri, Professor at the Max Planck Institute studying human palaeosystems and pan-African Homo sapiens origins. She discusses early Homo sapiens in Saudi Arabia and green corridors that enabled dispersals. She explores human presence in African rainforests and evidence from Anyama. She reveals unexpected Mesolithic seafaring to Malta and a major expansion of the human ecological niche around 70–50k years ago.

INSIGHT

Repeated Early Entries Into Arabia

  • Homo sapiens entered Arabia multiple times during wetter interglacial periods when the Sahara-Arabian arid belt shrank.
  • Fossils (e.g., a finger bone ~85–90 ka) and stone tools show repeated human presence but uneven preservation hides earlier arrivals.
INSIGHT

Green Arabia Enabled Long-Distance Movement

  • Arabian deserts hosted large lakes and hippos during wetter periods, creating 'Green Arabia' corridors.
  • These waterways would have enabled humans and other animals to disperse deep into the peninsula.
INSIGHT

Multiple Routes Into And Across Arabia

  • Northern (Sinai) and southern (Bab al-Mandab) routes both offered access to Arabia, but northern inland waterways were more consistently passable.
  • Wadis, lakes and western highlands provided multiple interior dispersal routes across the peninsula.
