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

ZB_5_06 — Mass Extinction Ecology: Catastrophe, Recovery, and Evolutionary Reset

Mass extinctions — episodes in which >75% of species disappear within a geologically brief interval — have profoundly shaped the history of life on Earth, acting as ecological and evolutionary resets that eliminate domin

R_2_05 — Missing Fossil Record and Punctuated Equilibrium

Darwin himself called the fossil record "the most obvious and gravest objection which can be urged against my theory" — because if evolution occurred through gradual transformation, we should find smooth transitional seq

ZB_5_05 — Extinction Biology and De-Extinction

Extinction — the complete disappearance of a species — is a permanent event that has shaped life's history as profoundly as origination. Background extinction (the normal, continuous loss of species) proceeds at ~0.1–1 s

R_5_20 — Mass Extinction Recovery: Post-Crisis Adaptive Radiation

Life on Earth has survived at least five major mass extinctions — the "Big Five" — each eliminating 75–96% of species. Yet each catastrophe was followed by a remarkable recovery phase in which surviving lineages radiated
