Spermatophyta Molecular Clock: Time Drift and Recent Acceleration

open access: yesPlant-Environment Interactions, Volume 6, Issue 5, October 2025.
Exponential increase in the base substitution rate in recent geologic time. ABSTRACT Angiospermae radiation is widely recognized as a mid‐Cretaceous event, but the adaptive radiation of Asarum and Viola as spring ephemerals also occurred during the Quaternary. To better understand the evolution of Angiospermae through geological time, a robust and well‐
