Coupling has emerged as a concept to describe the transition from differentiated
populations to newly evolved species through the strengthening of reproductive isolation …

Skin pigment patterns of vertebrates are stunningly diverse, and nowhere more so than in
teleost fishes. Several species, including relatives of zebrafish, recently evolved cichlid …

Adaptive radiations represent some of the most remarkable explosions of diversification
across the tree of life. However, the constraints to rapid diversification and how they are …

The genetic architecture of speciation, ie, how intrinsic genomic incompatibilities promote
reproductive isolation (RI) between diverging lineages, is one of the best-kept secrets of …

Endogenous retroviruses (ERVs) record past retroviral infections, providing molecular
archives for interrogating the evolution of retroviruses and retrovirus-host interaction …

The phylogeny and speciation of subterranean zokors in China are unclear, as previous
studies on morphology and limited molecular markers have generated conflicting results …

The formation of new species generates biodiversity and is often driven by evolution through
natural selection. However, the number of genetic changes involved in speciation is largely …

When challenged by similar environmental conditions, phylogenetically distant taxa often
independently evolve similar traits (convergent evolution). Meanwhile, adaptation to extreme …

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 …

A major unresolved issue in biology is why phenotypic and genetic variation is sometimes
continuous, yet other times packaged into discrete units of diversity, such as morphs …
