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 …

Neoplasms are microcosms of evolution. Within a neoplasm, a mosaic of mutant cells
compete for space and resources, evade predation by the immune system and can even …

Polyploidy has long been considered a major force in plant evolution. G. Ledyard Stebbins,
Jr., an architect of the Modern Synthesis, elegantly addressed a broad range of topics, from …

Whole genome duplication (leading to polyploidy) is widely accepted as an important
evolutionary force in plants, but it is less recognized as a driver of animal diversification …

Unreduced gametes (gametes with the somatic chromosome number) are known to facilitate
polyploid formation. Unreduced gametes result from a plethora of different mechanisms …

Although polyploidy has been involved in speciation in both animals and plants, the general
perception is often that it is too rare to have been a significant factor in animal evolution and …

The merging of distinct genomes, allopolyploidization, is a widespread phenomenon in
plants. It generates adaptive potential through increased genetic diversity, but examples …

Cancer is driven by the somatic evolution of cell lineages that have escaped controls on
replication and by the population-level evolution of genes that influence cancer risk. We …

Whole genome duplication leads to autopolyploidy and brings about an increase in cell size,
concentration of secondary metabolites and enhanced cytosine methylation. The increased …

The last decade highlighted polyploidy as a rampant evolutionary process that triggers
drastic genome reorganization, but much remains to be understood about their causes and …
