Phylogenetics provides a practical introduction to phylogenetic trees, including the kinds of data and methods used to construct them, and their uses across many fields of modern biology. The text is aimed at undergraduate and postgraduate students new to the subject area.· Oxford Biology Primers are the only resource to introduce prospective and current students of undergraduate-level bioscience to a range of topics from this dynamic experimental science, enticing readers to study further· Its titles directly support two key transitions in the student journey: from school to undergraduate-level study, and from undergraduate to independent researcher· Its modular format offers a high degree of flexibility, with teachers being able to draw on specific volumes that augment the post-16 curriculum, university lecturers being able to draw on specific volumes at different stages of the undergraduate curriculum · All titles in the series are available for students and institutions to purchase in a variety of formats: the e-book and Science Trove offer a mobile experience and convenient access along with functionality tools, navigation features, and links that offer extra learning support.

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.
