Knowing phylogenetic relationships among species is fundamental for many studies in
biology. An accurate phylogenetic tree underpins our understanding of the major transitions …

Alleles that introgress between species can influence the evolutionary and ecological fate of
species exposed to novel environments. Hybrid offspring of different species are often unfit …

Genome-scale sequence data have invigorated the study of hybridization and introgression,
particularly in animals. However, outside of a few notable cases, we lack systematic tests for …

Phylogenomics has revealed the remarkable frequency with which introgression occurs
across the tree of life. These discoveries have been enabled by the rapid growth of methods …

Analyses of genome sequence data have revealed pervasive interspecific gene flow and
enriched our understanding of the role of gene flow in speciation and adaptation. Inference …

Insects comprise over half of all described animal species. Together with the Protura
(coneheads), Collembola (springtails) and Diplura (two-pronged bristletails), insects form …

Species tree estimation is a basic part of many biological research projects, ranging from
answering basic evolutionary questions (eg, how did a group of species adapt to their …

Species delimitation is the process of determining which groups of individual organisms
constitute different populations of a single species and which constitute different species …

Cross-species introgression can have significant impacts on phylogenomic reconstruction of
species divergence events. Here, we used simulations to show how the presence of even a …

In the past two decades, genomic data have been widely used to detect historical gene flow
between species in a variety of plants and animals. The Tamias quadrivittatus group of North …
