E_2_11 — Snowball Earth Hypothesis

The Snowball Earth hypothesis proposes that Earth's surface was entirely or nearly entirely covered by ice on at least two occasions during the Neoproterozoic era (c. 720–635 million years ago): the Sturtian glaciation (

E_5_07 — Post-Extinction Recovery Patterns: Adaptive Radiation After Mass Dying

Mass extinctions are not merely episodes of destruction — they fundamentally reshape the trajectory of life through the recovery dynamics that follow. Post-extinction recovery is typically slow (5–10 million years for fu

E_5_05 — Late Devonian Mass Extinction: Kellwasser and Hangenberg Events

The Late Devonian mass extinction (~372–359 Ma) was not a single catastrophe but a series of extinction pulses spanning approximately 25 million years, making it unique among the "Big Five" mass extinctions. The two most

INTERDOC_64 — Cross-Cultural Constellations: Independent Invention vs. Diffusion as a Knowledge-Transmission Probe

The 88 modern IAU constellations are a cultural product — 48 from Ptolemy (~150 CE, derived from Mesopotamian/Babylonian sources), 12 from Keyser and de Houtman (~1596, Dutch East Indies), and 28 filled in by 17th–18th c

ZD_2_12 — Generative AI: Large Language Models, Diffusion, and the Transformer Revolution

Generative AI refers to artificial intelligence systems capable of creating new content — text, images, audio, video, code, 3D models — that is novel, coherent, and often indistinguishable from human-created work. The fi

The question of whether mass extinctions follow a periodic pattern — recurring at regular intervals driven by astronomical or geological cycles — has been one of the most provocative and contentious hypotheses in paleont
