Fossil-calibrated Bayesian analyses combine clock-like exons and broader RAG sampling; divergence times and biogeographic histories are model outputs, not direct fossil observations.
Claim ledger
divergence-time · mediumBayesian fossil-calibrated analyses of clock-like exons and broader RAG sampling infer a modern-bird common ancestor near 95 Ma and rapid diversification around the K–Pg boundary; dates and geographic histories are model outputs conditioned on topology, calibrations and priors.
