Introduction The notion that species boundaries can be porous to introgression is increasingly
accepted. Yet the broader role of introgression in evolution remains contentious and …

Speciation events often occur in rapid bursts of diversification, but the ecological and genetic
factors that promote these radiations are still much debated. Using whole transcriptomes …

When multiple speciation events occur rapidly in succession, discordant genealogies due to
incomplete lineage sorting (ILS) can complicate the detection of introgression. A variety of …

Premise of the Study Phylogenetic support has been difficult to evaluate within the green
plant tree of life partly due to a lack of specificity between conflicted versus poorly informed …

When speciation events occur in rapid succession, incomplete lineage sorting (ILS) can cause
disagreement among individual gene trees. The probability that ILS affects a given locus …

Understanding the types and functions of genes that are able to cross species boundaries—and
those that are not—is an important step in understanding the forces maintaining species …

Identifying the molecular process of complex trait evolution is a core goal of biology.
However, pinpointing the specific context and timing of trait-associated changes within the …

Adaptive evolution requires both raw genetic material and an accessible path of high fitness
from one fitness peak to another. In this study, we used an introgression line (IL) population …

The evolution of a pair of chromosomes that differ in appearance between males and females
(heteromorphic sex chromosomes) has occurred repeatedly across plants and animals. …
