PhD student in molecular evolution / phylogenetics / palaeobiology @ University of Bristol. Interested in providing a timescale for the tree of life to elucidate major evolutionary innovations in Earth history. 🧬
@sidney-davies.bsky.socialTake home message: driven by priors, different methods support competing scenarios for croc evolution.
To find out which method we think is closest to the truth, follow the link to the paper!

@sidney-davies.bsky.socialWhy? Running analyses without sequence data showed that strategy-specific priors strongly influence the posterior, potentially biasing estimates.
@sidney-davies.bsky.socialWe found the age of Crocodylia 🐊 was heavily influenced by dating method: Node calibration: ~95–78 Ma FBD: ~118–95 Ma Tip calibration: ~125–102 Ma
@sidney-davies.bsky.socialOur new paper is out! We find that different molecular clock methods recover distinct evolutionary timescales.
