Primes

• Continuity vs. Rupture
  • Historiography (the Renaissance, Industrial Revolution, 1789, 1917, 1989 debates), political history (regime change vs. regime continuity under new leadership), economic history (industrial take-off vs. long-accumulation models), art history (movement boundaries), philosophy of science (Kuhnian revolutions vs. gradualist alternatives), evolutionary biology (Eldredge-Gould punctuated equilibrium debate), physics (continuous vs. first- order phase transitions), organizational change management (incremental vs. transformation initiatives), and software engineering (patch vs. major-version vs. ground-up-rewrite decisions), with Eldredge and Gould (1972) extending the dimension into evolutionary biology.

    This sourceFoundational paleobiological argument that species evolution shows long stasis punctuated by rapid speciation rather than smooth gradualism; canonical biological transfer of the continuity-vs-rupture dimension (supports D41-021 extension into biology and D41-025 resolution-dependent reading of the fossil record).

• Critical Juncture
  • What seems like a small geographic separation becomes an irreversible divergence in trait distributions, reproductive compatibility, and adaptive radiation paths, the punctuated-equilibrium dynamic Eldredge and Gould (1972) identified in the fossil record.

    This sourceArgues species evolution shows long stasis punctuated by rapid speciation; supports the evolutionary speciation/branching example.

• Metasystem Transition
  • Additional canonical reference:

    This sourceFreeman, Cooper. Foundational paleobiological argument that species evolution shows long stasis punctuated by rapid speciation rather than smooth gradualism; canonical biological transfer of the continuity-vs-rupture dimension and template for cross-domain "punctuated equilibrium" analogies.

• Punctuated Equilibrium
  • A gradualist model predicts a uniform or normal distribution of increments; a punctuated model predicts a heavy-tailed distribution, most increments near zero and rare giant ones.
