M_5_07 — Impossible Ancient Maps of Antarctica: Critical Assessment

Among the most provocative claims in alternative history is the assertion that several medieval and Renaissance-era maps depict Antarctica — a continent not officially discovered until 1820 and not mapped until the 20th

M_4_13 — Earth Crustal Displacement: Hapgood's Theory and Its Legacy

Earth crustal displacement (ECD) — the hypothesis that the Earth's lithosphere can shift as a relatively intact shell over the underlying asthenosphere, rapidly relocating the geographic positions of continents relative

ZF_4_11 — Sea Ice Dynamics and Polar Oceanography

Sea ice — frozen seawater that forms a thin crust (typically 1–4 m thick) over polar and subpolar oceans — is one of Earth's most dynamic and climate-sensitive features, playing a disproportionate role in global climate

L_2_05 — Americas Peopling Genetics

The peopling of the Americas is one of the clearest cases where ancient DNA and archaeology have converged to overturn an older narrative. The core model now favored by genetics is that the main ancestry of Indigenous Am

L_2_09 — Genetic History of the Americas: Clovis to Contact

The genetic history of the Americas — from the initial peopling of the New World to the devastating population collapse after European contact — is one of the most intensively studied and rapidly evolving areas of paleog

F_1_22 — Peopling of the Americas: Routes & Chronology

The peopling of the Americas — when, how, and by whom the Western Hemisphere was first colonized by modern humans — is one of the most actively debated questions in archaeology, genetics, and paleoanthropology, with the

F_1_07 — First Americans Debate — Clovis, Pre-Clovis, and Coastal Routes

The question of when and how humans first reached the Americas has been transformed in the 21st century by a series of discoveries that have demolished the long-reigning "Clovis-first" paradigm. For decades, the archaeol
