Including autapomorphies is important for paleontological tip-dating with clocklike data, but not with non-clock data

Matzke, Nicholas; Irmis, Randall B.

Description

Tip-dating, where fossils are included as dated terminal taxa in Bayesian dating inference, is an increasingly popular method. Data for these studies often come from morphological character matrices originally developed for non-dated, and usually parsimony, analyses. In parsimony, only shared derived characters (synapomorphies) provide grouping information, so many character matrices have an ascertainment bias: they omit autapomorphies (unique derived character states), which are considered...[Show more]
