In the past decade, advances in genome sequencing have allowed researchers to uncover
the history of hybridization in diverse groups of species, including our own. Although the …

Hybridization may drive rare taxa to extinction through genetic swamping, where the rare
form is replaced by hybrids, or by demographic swamping, where population growth rates …

Groundbreaking research on the universality and diversity of microorganisms is now
challenging the life sciences to upgrade fundamental theories that once seemed …

Intrinsic postzygotic barriers can play an important and multifaceted role in speciation, but
their contribution is often thought to be reserved to the final stages of the speciation process …

As populations diverge, genetic differences accumulate across the genome. Spurred by
rapid developments in sequencing technology, genome-wide population surveys of natural …

Background Polyploidy or whole-genome duplication is now recognized as being present in
almost all lineages of higher plants, with multiple rounds of polyploidy occurring in most …

Speciation is a fundamental evolutionary process, the knowledge of which is crucial for
understanding the origins of biodiversity. Genomic approaches are an increasingly …

Fruit flies of the genus Drosophila have been an attractive and effective genetic model
organism since Thomas Hunt Morgan and colleagues made seminal discoveries with them …

The prevalence of autopolyploids in angiosperms has long been a subject of debate.
Müntzing (1936) and Darlington (1937) concluded that autopolyploids were common and …

Background Taxonomy is the biological discipline that identifies, describes, classifies and
names extant and extinct species and other taxa. Nowadays, species taxonomy is …
