WASHINGTON — Huw Groucutt passes rolling sand dunes as far as his eye can see when traveling to archaeological sites in the northern Arabian Peninsula.
But the Arabian Peninsula may have also played an important role as a bridge between Africa and Eurasia, a study published Wednesday in the journal“Arabia has not been part of the story of early human migration because so little work was done there before,” said co-author Michael Petraglia, a paleolithic archaeologist at the Max Planck Institute for the Science of Human History in Jena, Germany.
Extensive excavations over a decade revealed stone tools from multiple periods of prehistoric settlement by early human groups, the oldest 400,000 years ago. Analysis of sediment samples from the ancient lakes and remains from hippos and other animals revealed that during several periods in the distant past, the peninsula hosted year-round lakes and grasslands.
“What this research group has done is really exquisitely combine archaeology and climate records going back 400,000 years to show that early humans moved across this landscape when the climate changed,” said paleoanthropologist Rick Potts, who directs the Human Origins Program at the Smithsonian’s National Museum of Natural History.
