TL;DR: New estimates for the incidence of polyploidy in ferns and flowering plants are presented based on a simple model describing transitions between odd and even base chromosome numbers, and it is indicated that ploidy changes may represent from 2 to 4% of speciation events in flowering plants and 7% in f Ferns.
Abstract: ▪ 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 polyploid lineages indicates that this phenomenon is a common and successful evolutionary transition, whether polyploidization itself has a significant effect on patterns and rates of diversification remains an open question. Here we review evidence for the creative role of polyploidy in evolution. We present new estimates for the incidence of polyploidy in ferns and flowering plants based on a simple model describing transitions between odd and even base chromosome numbers. These new estimates indicate that ploidy changes may represent from 2 to 4% of speciation events in flowering plants and 7% in ferns. Speciation via polyploidy is likely to be one of the more predominant modes of sympatric speciation in plants, owing to its potentially broad-scale effects on gene regulation and developmental processes, effects that can produce immed...
TL;DR: This volume presents the newest findings from their studies and brings readers up to date on species concepts, modes of speciation, the nature of reproductive barriers, the forces that drive divergence of populations, the genetic control of reproductive isolation, and the role played by hybrid zones and hybridization in speciation.
Abstract: Speciation is one of the great themes of evolutionary biology. It is the process through which new species are born and diversity generated. In this volume, thirty authors at the forefront of research into speciation present the newest findings from their studies and bring readers up to date on species concepts, modes of speciation, the nature of reproductive barriers, the forces that drive divergence of populations, the genetic control of reproductive isolation, and the role played by hybrid zones and hybridization in speciation.
