M_4_12 — Pre-Clovis Sites Compilation: Monte Verde to Cerutti Mastodon
For most of the 20th century, the "Clovis First" paradigm held that the first humans to enter the Americas were the bearers of the Clovis culture — characterized by distinctive fluted stone points — who arrived via the i
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_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
F_1_10 — Kennewick Man and the Pre-Clovis Debate
The question of when and how humans first reached the Americas has been one of archaeology's most contentious debates for over a century. For decades, the Clovis First model dominated: the earliest Americans were big-gam
H_2_06 — Successful Paradigm Shifts in Archaeology: Cases Where Orthodoxy Was Wrong
The history of science contains well-documented cases where firmly held orthodoxies were overturned by new evidence, often after decades of resistance from established authorities. Thomas Kuhn's The Structure of Scientif
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
M_4_09 — Younger Dryas Impact and Lost Civilization Hypothesis
The Younger Dryas Impact Hypothesis (YDIH) proposes that a cosmic impact or airburst event approximately 12,800 years ago (12.8 ka BP) triggered the Younger Dryas cold reversal — a ~1,300-year return to near-glacial cond
E_3_18 — Black Mat: Younger Dryas Boundary Layer Geochemistry
The "black mat" is a thin, dark, organic-rich sedimentary layer found at dozens of archaeological and geological sites across North America, dating to the onset of the Younger Dryas stadial (~12,800 cal BP). First system
E_3_03 — Ice Age Civilizations — Evidence for Complexity During the Last Glacial Maximum
The Last Glacial Maximum (LGM, ~26,500-19,000 BP) — when ice sheets covered ~32% of the global land surface and sea levels dropped ~120 meters below present — was not a period of human stagnation but of remarkable cultur
E_4_26 — Younger Dryas Impact Evidence: A Comprehensive Review
The Younger Dryas Impact Hypothesis (YDIH) proposes that one or more extraterrestrial objects (comet or asteroid fragments) struck or exploded over the Earth approximately 12,900 years ago (12.9 ka BP), triggering the Yo
E_1_01 — The Younger Dryas Impact Hypothesis (YDIH)
This document examines The Younger Dryas Impact Hypothesis (YDIH), a topic within the Cataclysms and Chronology research area. Notable findings include: Greenland ice-core data confirm rapid cooling at onset and abrupt w
INTERDOC_26 — Forbidden Archaeology and Paradigm Gatekeeping
Thomas Kuhn (The Structure of Scientific Revolutions, 1962) demonstrated that science does not progress by smooth accumulation of knowledge but through paradigm shifts: periods of "normal science" (working within accepte
O_2_22 — Carolina Bay Anomalies
The Carolina bays are a collection of approximately 500,000 shallow, elliptical depressions concentrated along the Atlantic Coastal Plain of the southeastern United States, from New Jersey to northern Florida, with the h
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
H_2_15 — Re-Dating Controversies: Sites Older Than Thought
The history of archaeology and prehistory is punctuated by re-dating controversies — cases where new evidence or improved dating technology revealed that sites, artifacts, or traditions were significantly older than prev
F_1_16 — Coastal Migration Hypothesis: Kelp Highway and Pacific Rim
The coastal migration hypothesis (also known as the "Kelp Highway" hypothesis) proposes that the initial human colonization of the Americas occurred not via the traditional ice-free corridor through the interior of North
F_1_12 — Beringia: Land Bridge, Migration, and Lost Landscape
Beringia — the vast landmass that periodically connected northeastern Asia to northwestern North America across what is now the Bering Strait and the shallow Chukchi and Bering Seas — was one of the most consequential ge
F_1_09 — Austronesian Expansion: The Greatest Maritime Migration
The Austronesian expansion is the most extensive pre-modern maritime migration in human history, covering over half the globe — from Taiwan to Madagascar, Easter Island, Hawaii, and New Zealand — over approximately 5,000
