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 …

Traditionally, cognitive and computer scientists have viewed intelligence solipsistically, as a
property of unitary agents devoid of social context. Given the success of contemporary …

Although some lineages of animals and plants have made impressive adaptive radiations
when provided with ecological opportunity, the propensities to radiate vary profoundly …

Explaining broad molecular, phenotypic and species biodiversity patterns necessitates a
unifying framework spanning multiple evolutionary scales. Here we argue that although …

Adaptive radiation is the likely source of much of the ecological and morphological diversity
of life,,–. How adaptive radiations proceed and what determines their extent remains unclear …

After decades of debate, biologists today largely agree that most speciation events require
an allopatric phase (that is, geographic separation), but the role of adaptive ecological …

Vocalizations of anuran amphibians have received much attention in studies of behavioral
ecology and physiology, but also provide informative characters for identifying and …

The species concept is the cornerstone of biodiversity science, and any paradigm shift in the
delimitation of species affects many research fields. Many biologists now are embracing a …

Species diversification—the balance between speciation and extinction—is fundamental to
our understanding of how species richness varies in space and time and throughout the …

We used 20 de novo genome assemblies to probe the speciation history and architecture of
gene flow in rapidly radiating Heliconius butterflies. Our tests to distinguish incomplete …
