Implication

Methodological review uncovers advances in molecular clock calibration across diverse lineages, highlighting the necessity of robust model testing for accurate divergence estimation.

Key Points

Review statistical and conceptual developments in estimating evolutionary divergence times from molecular data spanning phylogenetic and population genetic timescales.
Evaluated nucleotide substitution models and analytical strategies addressing among-site and among-lineage evolutionary rate variation.
Assessed population genetic frameworks that integrate ancestral demographic processes into divergence dating for closely related species.
Accounting for rate heterogeneity across lineages and genetic sites significantly reduces error in phylogenetic divergence time estimates.
Incorporating ancestral coalescent processes into dating analyses resolves time-scale discrepancies when separating recent speciation events from gene divergence.
