Hybridization, or interbreeding between different taxa, was traditionally considered to be
rare and to have a largely detrimental impact on biodiversity, sometimes leading to the …

Main conclusion This article provides an up-to-date review concerning from basic issues of
polyploidy to aspects regarding the relevance and role of both natural and artificial …

Polyploidy is a key mechanism of genome evolution and speciation, particularly in plants.
Many aspects of polyploidy have been elucidated with the tools that have become available …

Hybridization has many and varied impacts on the process of speciation. Hybridization may
slow or reverse differentiation by allowing gene flow and recombination. It may accelerate …

Investigators have long searched for a polyploidy paradigm—rules or principles that might
be common following polyploidization (whole‐genome duplication, WGD). Here we attempt …

Many organisms are currently polyploid, or have a polyploid ancestry and now have
secondarily'diploidized'genomes. This finding is surprising because retained whole-genome …

Most flowering plants have been shown to be ancient polyploids that have undergone one
or more whole genome duplications early in their evolution. Furthermore, many different …

Despite the importance of polyploidy and the increasing availability of new genomic data,
there remain important gaps in our knowledge of polyploid population genetics. These gaps …

Species are generally viewed by evolutionists as 'real'distinct entities in nature, making
speciation appear difficult. Charles Darwin had originally promoted a very different …

Explaining the evolution of species geographical ranges is fundamental to understanding
how biodiversity is distributed and maintained. The solution to this classic problem in …
