The corridor shows human occupation in 5 of 6 tested epochs spanning 130,000 BP to the present. The single gap (LGM, 26–14k BP) is expected — Arabia was impassable during peak glaciation.
Bronze Age monuments sit ∼55× closer to early Holocene campsites than chance (p = 0.004), confirming the corridor was inherited, not invented.
