Hybridization has long been recognized as a fundamental evolutionary process in plants
but, until recently, our understanding of its phylogenetic distribution and biological …

Studies of plants have been instrumental for revealing how new species originate. For
several decades, botanical research has complemented and, in some cases, challenged …

It is increasingly realized that homoploid hybrid speciation (HHS), which involves no change
in chromosome number, is an important mechanism of speciation. HHS will likely increase in …

Hybridization can drive speciation. We examine the hypothesis that Castanea henryi var.
omeiensis is an evolutionary lineage that originated from hybridization between two near …

Although more frequently discussed recently than previously, the role of ecology in
homoploid hybrid and allopolyploid speciation has not been subjected to comparative …

Cytogenetics and genomics have completely transformed our understanding of evolutionary
genome change since the early 1950s. The point of this paper is to outline some of the …

Genome change does not occur accidentally. The conventional Modern Synthesis view of
gradual evolution guided solely by natural selection fails to incorporate many important …

Hybridisation is well documented in many species, especially plants. Although hybrid
populations might be short-lived and do not evolve into new lineages, hybridisaiton could …

Two major developments have made it possible to use examples of ecological radiations as
model systems to understand evolution and ecology. First, the integration of quantitative …

Hybridisation can lead to homoploid hybrid speciation, ie, the origin of new species without
change in chromosome number between parents and offspring. Central to homoploid hybrid …
