The origin of new homoploid species via hybridization is theoretically difficult because it
requires the development of reproductive isolation in sympatry. Nonetheless, this mode is …

Although the evolutionary importance of natural hybridization has been debated for
decades, it has become increasingly clear that hybridization plays a fundamental role in the …

The importance of hybridization in plant speciation and evolution has been debated for
decades, with opposing views of hybridization as either a creative evolutionary force or …

The concept that species may arise through the gradual divergence of races has been and
remains widely accepted by plant evolutionists. Evidence in its favor is circumstantial. It is …

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 …

Most diploid species have unique polygenic systems; since they are complex and
coadapted throughout the genome, their integrity is not easily perturbed. A recent theory …

Homoploid hybrid speciation is the origin of a hybrid species without change in chromosome
number. Although currently thought to be a rare form of speciation, especially relative to the …

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

Studies of natural hybridization have generally addressed evolutionary ques-tions using one
of the three following frameworks:(i) taxonomy or systematics (57, 59, 73, 79, 111, 172);(ii) …

Natural hybridization between closely related taxa is a common phenomenon in both plants
and animals. Hybridization has often been viewed as a destructive force that could erode …
