Persistence Selection Between Simulated Biogeochemical Cycle Variants For Their Distinct Effects On The Earth System

The average long-term impact of Darwinian evolution on Earth’s habitability remains extremely uncertain. Recent attempts to reconcile this uncertainty by “Darwinizing” nonreplicating biogeochemical processes subject to persistence-based selection conform with […]
