On the instability and evolutionary age of deep-sea chemosynthetic communities (2013, background): “Variability also exists in the conditions necessary for fossilization; thus, initial appearance in the fossil record will undoubtedly be younger than a taxon’s origin (Smith and Peterson, 2002).”
Systematic Revision of Symbiodiniaceae Highlights the Antiquity and Diversity of Coral Endosymbionts. (2018, background): “The reliability of molecular dating is not only dependent on accurate calibration points but also on a relatively robust phylogeny [44].”
The origin and evolution of model organisms (2002, background): “However, counter-arguments to that hypothesis have been mad”
Tempo and mode of early animal evolution: inferences from rocks, Hox, and molecular clocks (2005, result): “Although problems exist with certain aspects of molecular clock analyses (Smith and Peterson 2002; Benton and Ayala 2003), two recent analyses came to the same conclusion: bilaterians arose ca. 600–630 Ma, and nephrozoans arose ca. 560–580 Ma (Aris-Brosou and Yang 2002, 2003; Peterson et al. 2004;…”
The modern molecular clock (2003, background): “The evolutionary dates measured by molecular clocks have been controversial, particularly if they clash with estimates taken from more traditional sources such as the fossil recor”
The New View of Animal Phylogeny (2004, background): “Several workers (e.g., Philippe et al. 1994, Smith & Peterson, 2002; see Graur & Martin 2004 for a particularly colorful discussion) have highlighted some of the problems with using a molecular clock to date deep divergences.”
Clades, Clocks, and Continents: Historical and Biogeographical Analysis of Myrtaceae, Vochysiaceae, and Relatives in the Southern Hemisphere (2004, background): “Issues with these approaches are known (Doyle and Donoghue 1993; Smith and Peterson 2002), but the use of multiple independent fossil calibration points can provide increased confidence in resulting dates.”
