Polyploidy has been hypothesized to be both an evolutionary dead-end and a source for
evolutionary innovation and species diversification. Although polyploid organisms …

Polyploidy, or the duplication of entire genomes, has been observed in prokaryotic and
eukaryotic organisms, and in somatic and germ cells. The consequences of polyploidization …

▪ Abstract Changes in ploidy occurred early in the diversification of some animal and plant
lineages and represent an ongoing phenomenon in others. While the prevalence of …

Polyploidy is an evolutionary innovation for many animals and all flowering plants, but its
impact on selection and domestication remains elusive. Here we analyze genome evolution …

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 …

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 …

Domesticated food crops are derived from a phylogenetically diverse assemblage of wild
ancestors through artificial selection for different traits. Our understanding of domestication …

Background Biological invasions are a major ecological and socio-economic problem in
many parts of the world. Despite an explosion of research in recent decades, much remains …

Hybridization may influence evolution in a variety of ways. If hybrids are less fit, the
geographical range of ecologically divergent populations may be limited, and prezygotic …

▪ Abstract Here we review the biology of early generation neopolyploids and discuss the
profound changes that accompany their formation. Newly formed auto-and allopolyploids …
