Title: the Impact of Fossils and Taxon Sampling on Ancient Molecular Dating Analyses
The number and complexity of molecular dating studies has increased over the past decade. Along with a broadening acceptance of their utility has come significant controversy over the methods and models that are appropriate, as well as the accuracy of the estimates yielded by molecular clock analyses. Radically different age estimates have been published for the same divergences from analyses o...

متن کاملFit of Fossils and Mammalian Molecular Trees: Dating Inconsistencies Revisited
Divergence time estimation requires the reconciliation of two major sources of data. These are fossil and/or biogeographic evidence that give estimates of the absolute age of nodes (ancestors) and molecular estimates that give us estimates of the relative ages of nodes in a molecular evolutionary tree. Both forms of data are often best characterized as yielding continuous probability distributi...
متن کاملMultigene Analyses of Monocot Relationships: a Summary
We present an analysis of supra-familial relationships of monocots based on a combined matrix of nuclear 18S and partial 26S rDNA, plastid atpB, matK, ndhF, and rbcL, and mitochondrial atp1 DNA sequences. Results are highly congruent with previous analyses and provide higher bootstrap support for nearly all relationships than in previously published analyses. Important changes to the results of...
متن کاملEffects of taxon sampling on molecular dating for within-genus divergence events, when deep fossils are used for calibration
A universal method of molecular dating that can be applied to all families and genera regardless of their fossil records, or lack thereof, is highly desirable. A possible method for eudicots is to use a large phylogeny calibrated using deep fossils including tricolpate pollen as a fixed (124 mya) calibration point. This method was used to calculate node ages within three species-poor disjunct b...
