Hybridization in plants and animals is more common and has more complex outcomes than
previously realized. Genome-wide analyses of introgression in organisms ranging from oaks …

While homoploid hybridization was viewed as maladaptive by zoologists, the possibility that
it might play a creative role in evolution was explored and debated by botanists during the …

The origin of novelty is a critical subject for evolutionary biologists. Early geneticists
speculated about the sudden appearance of new species via special macromutations …

Hybridization and polyploidization are important processes for plant evolution. However,
classification of hybrid or polyploid species has been notoriously difficult because of the …

Biologists have assumed that heritable variation due to DNA sequence differences (ie,
genetic variation) allows populations of organisms to be both robust and adaptable to …

Homoploid hybrid speciation has been recognized for its potential rapid completion, an idea
that has received support from experimental and modeling studies. Following initial …

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

Long a major focus of genetic research and breeding, sunflowers (H elianthus) are
emerging as an increasingly important experimental system for ecological and evolutionary …

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 …

Habitats that differ in soil resource availability are expected to differ for selection on resource‐
related plant traits.• Here, we examined spatial and temporal variation in phenotypic …
