Domestication, a process of increasing mutual dependence between human societies and
the plant and animal populations they target, has long been an area of interest in genetics …

Asexual organisms usually have larger and more northern distributions than their sexual
relatives. This phenomenon, called geographical parthenogenesis, has been controversially …

The role of hybridization in adaptive evolution is contentious. While many cases of adaptive
trait introgression have been proposed, the relevant traits have rarely been identified …

The importance of geographic isolation in speciation has been debated since the 19th
century. Since the beginning of the 20th century, the consensus has been that most …

The idea that natural hybridization has served as an important force in evolutionary and
adaptive diversification has gained considerable momentum in recent years. By combining …

Understanding the genetic architecture of reproductive barriers and the evolutionary forces
that drove their divergence represents a considerable challenge towards understanding …

Recent attempts to address the long-debated 'origin'of the angiosperms depend on a
phylogenetic framework derived from a matrix of taxa versus characters; most assume that …

Determining the genetic structure of isolated or fragmented species is of critical importance
when planning a suitable conservation strategy. In this study, we use nuclear and …

The swordlike exaggerated caudal fin extensions of male swordtails are conspicuous traits
that are selected for through female choice. Swords are one of only few examples where the …

Background and Aims Paris (Melanthiaceae) is a temperate genus of about 24 perennial
herbaceous species distributed from Europe to eastern Asia. The delimitation of the genus …
