Best Practices for Justifying Fossil Calibrations?
-----------------------------------------------------------------------------------2011/9/21 Systematic Biology
The lack of rigorous protocols for assigning calibrations based on fossils raises serious questions about the credibility of divergence dating results (e.g.,?Shaul and Graur 2002;?Brochu et al. 2004;?Graur and Martin 2004;?Hedges and Kumar 2004;?Reisz and Müller 2004a,?2004b;?Theodor 2004;?van Tuinen and Hadly 2004a,?2004b;?van Tuinen et al. 2004;?Benton and Donoghue 2007;?Donoghue and Benton 2007;?Parham and Irmis 2008;?Ksepka 2009;?Benton et al. 2009;?Heads 2011).
挑選化石校正點(diǎn)，來推斷物種分歧時(shí)間这吻〉醯担化石校正點(diǎn)如何挑選的，我真的是不懂唾糯，所以就來讀讀文章了怠硼。
We do not deny that a posteriori methods are a useful means of evaluating calibrations, but there can be no substitute for a priori assessment of the veracity of paleontological data.
posteriori 和 priori是什么意思
?We likewise encourage biologists relying on nonfossil calibrations for molecular divergence estimates (e.g., ages of island or mountain range formations, continental drift, and biomarkers) to develop their own set of rigorous guidelines so that their calibrations may also be evaluated in a systematic way.
還可以不通過化石，通過島或者山的形成時(shí)間移怯，板塊漂移香璃，生物標(biāo)志物。（太深奧了舟误，感覺自己像白癡）
