Phys · · 704 words · By Spanish National Research Centre

Researchers from several Spanish and European institutions have discovered stone tools at Revilleja de Valparaíso in Spain dating back approximately 700,000 years. The findings suggest that Acheulean technological traditions from North Africa reached the Iberian Peninsula earlier than previously believed.
