ZB_5_19 — The Anthropocene: Human Dominance of Earth Systems and Epoch Dating

The Anthropocene — a proposed geological epoch defined by the dominant influence of human activity on Earth's geology, climate, and ecosystems — has become one of the most consequential and contentious concepts in modern

E_5_06 — Holocene Sixth Mass Extinction: Current Biodiversity Crisis

The Holocene "Sixth Mass Extinction" hypothesis holds that current species loss rates are 100–1,000 times the normal background extinction rate, driven primarily by human activity: habitat destruction, overexploitation,

INTERDOC_57 — Cascade Pattern Across Civilization Resets

Three civilization-altering events — the Younger Dryas climate reversal (c. 12,800 years ago), the Late Bronze Age Collapse (c. 1177 BCE), and the Justinianic Plague (541–549 CE and centuries of recurrence) — share struc

R_1_03 — Mass Extinction Events

Life on Earth has endured at least five catastrophic mass extinctions in 540 million years, each eliminating 60–96% of all species. The "Big Five" are: End-Ordovician (~443 Mya, ~85% species lost), Late Devonian (~372 My
