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 …

Hybridization is an evolutionary phenomenon that has fascinated biologists for centuries.
Prior to the advent of whole-genome sequencing, it was clear that hybridization had played …

Hybridization allows adaptations to be shared among lineages and may trigger the evolution
of new species,. However, convincing examples of homoploid hybrid speciation remain rare …

It has long been recognized that hybridization and polyploidy are prominent processes in
plant evolution. Although classically recognized as significant in speciation and adaptation …

Studies of plants have been instrumental for revealing how new species originate. For
several decades, botanical research has complemented and, in some cases, challenged …

Although species can arise through hybridization, compelling evidence for hybrid speciation
has been reported only rarely in animals. Here, we present phylogenomic analyses on …

It is increasingly realized that homoploid hybrid speciation (HHS), which involves no change
in chromosome number, is an important mechanism of speciation. HHS will likely increase in …

Much of what we know about speciation comes from detailed studies of well‐known model
systems. Although there have been several important syntheses on speciation, few (if any) …

Understanding the processes of population divergence and speciation remains a core
question in evolutionary biology. For nearly a hundred years evolutionary geneticists have …

Using a combination of DNA barcodes and morphology, we examine species boundaries in
bees of the genus Andrena subgenus Taeniandrena in Europe. First, we solve the long …
