Phyletic Gradualism
Updated 2026-08-02
INTRODUCTION
English translation pending.
CORE DEFINITION
Phyletic gradualism holds that species evolve through small, incremental variations accumulated over long stretches of geological time, so the rate of change is roughly uniform. Because fossil preservation is sparse and the intervals are enormous, transitional forms are seldom recorded, which makes change look abrupt in the rocks.
SCAFFOLDING EFFECT
Reduce cognitive load
- Assume a slow build: when success looks sudden, look for the long accumulation beneath it - Trace the small steps: reconstruct the tiny gains that preceded the visible leap - Keep compounding: invest in small improvements whose payoff only appears after a long delay
Anchor fast decisions
Small heritable variations accumulate generation by generation, so the rate of change is roughly steady rather than bursty. Because rock sequences capture only occasional snapshots across immense intervals, the intermediate steps are rarely preserved, and the record appears to jump. The apparent discontinuity is a sampling artifact rather than evidence of sudden origins.
