The geography of speciation has long been contentious. In recent years, phylogenetic
approaches have been proposed to determine the geographical mode of speciation. If …

We introduce a general approach for investigating the role of geography in speciation,
based on analyzing the geography of sister clades across all nodes in a species-level …

The tradition of classifying cases of speciation into discrete geographic categories
(allopatric, parapatric and sympatric) fuelled decades of fruitful research and debate. Not …

Speciation has been a major focus of evolutionary biology research in recent years, with
many important advances. However, some of the traditional organising principles of the …

Species-level phylogenies derived from molecular data provide an indirect record of the
speciation events that have led to extant species. This offers enormous potential for …

This article considers the statistical issues relevant to the comparative method in
evolutionary biology. A generalized linear model (GLM) is presented for the analysis of …

▪ Abstract Polymorphism, or variation within species, is common in all kinds of data and is
the major focus of research on microevolution. However, polymorphism is often ignored by …

For the last five decades the theory of geographic or allopatric speciation has enjoyed
overwhelming acceptance; the burden of proof, with the exception of polyploidy and similar …

Systematists and population geneticists can both use molecular data sets to construct
evolutionary trees (species and gene trees, respectively), and then use the resulting …
