Understanding the Tripartite Approach to Bayesian Divergence Time Estimation

By: Rachel C. M. Warnock,April M. Wright

Placing evolutionary events in the context of geological time is a fundamental goal in paleobiology and macroevolution. In this Element we describe the tripartite model used for Bayesian estimation of time calibrated phylogenetic trees. The model can be readily separated into its component models: the substitution model, the clock model and the tree model. We provide an overview of the most widely used models for each component and highlight the advantages of implementing the tripartite model within a Bayesian framework.

Literary History Writing, 1770-1820

By: April London

This investigation of literary history writing between 1770 and 1820 identifies the mode's distinction from canon formation as central to its cultural vitality. Using secret history, memoir and the novel, amongst other sources, it invites a re-thinking of literary history's place in late eighteenth and early nineteenth-century print culture.

Testing Character Evolution Models in Phylogenetic Paleobiology

A case study with Cambrian echinoderms

By: April Wright,Peter J. Wagner,David F. Wright

Macroevolutionary inference has historically been treated as a two-step process, involving the inference of a tree, and then inference of a macroevolutionary model using that tree. Newer models blend the two steps. These methods make more complete use of fossils than the previous generation of Bayesian phylogenetic models. They also involve many more parameters than prior models, including parameters about which empiricists may have little intuition. In this Element, we set forth a framework for fitting complex, hierarchical models. The authors ultimately fit and use a joint tree and diversification model to estimate a dated phylogeny of the Cincta (Echinodermata), a morphologically distinct group of Cambrian echinoderms that lack the fivefold radial symmetry characteristic of extant members of the phylum. Although the phylogeny of cinctans remains poorly supported in places, this Element shows how models of character change and diversification contribute to understanding patterns of phylogenetic relatedness and testing macroevolutionary hypotheses.
