Genome-scale data and the development of novel statistical phylogenetic approaches have
greatly aided the reconstruction of a broad sketch of the tree of life and resolved many of its …

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 …

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 …

Over 100 years of studies in Drosophila melanogaster and related species in the genus
Drosophila have facilitated key discoveries in genetics, genomics, and evolution. While high …

The origin of a land flora fundamentally shifted the course of evolution of life on earth,
facilitating terrestrialization of other eukaryotic lineages and altering the planet's geology …

The Viridiplantae comprise two main clades, the Chlorophyta (including a diverse array of
marine and freshwater green algae) and the Streptophyta (consisting of the freshwater …

Antimicrobial peptides are host-encoded immune effectors that combat pathogens and
shape the microbiome in plants and animals. However, little is known about how the host …

Facultative parthenogenesis enables sexually reproducing organisms to switch between
sexual and asexual parthenogenetic reproduction. To gain insights into this phenomenon …

A recurring feature of oceanic archipelagos is the presence of adaptive radiations that
generate endemic, species-rich clades that can offer outstanding insight into the links …

Species are the fundamental units of life and evolution. Their recognition is essential for
science and society. Molecular methods have been increasingly used for the identification of …
