From Migration to Monumentality: The Alison Great Circle as a 60,000-Year Human Corridor

This preprint presents twelve independent statistical analyses testing the mechanism behind a monument-settlement divergence along a specific great circle (pole: 59.682122°N, 138.646087°W). The corridor shows archaeological enrichment across five of six tested epochs spanning 60,000 years. Monumental sites cluster at 2.52× the expected rate (Z = 6.74, land-constrained baseline) while settlements do not (Z = −2.91). In Egypt, the circle intersects the Ahramat Branch near-perpendicularly at the densest pyramid concentration (p = 0.00016). Fifteen alternative hypotheses return null results. We propose the corridor is consistent with the southern coastal Out-of-Africa dispersal route. Companion study: doi.org/10.5281/zenodo.19212669
