Many groups of closely related species have reticulate phylogenies. Recent genomic
analyses are showing this in many insects and vertebrates, as well as in microbes and …

Biologists have forever sought to understand how species arise and persist. Historically,
species that rarely interbreed, or are reproductively isolated, were considered the norm …

Reticulate evolution, whether due to lateral gene transfer, introgression, incomplete lineage
sorting, or hybrid speciation, is a ubiquitous phenomenon, yet systematists have few tools for …

In eukaryotes, chromosomal rearrangements, such as inversions, translocations and
duplications, are common and range from part of a gene to hundreds of genes. Lineage …

Species hybridization is reviewed focusing on its role as a source of evolutionary novelties.
Contrary to the view that hybrids are lineages devoid of evolutionary value, a number of …

Background Phylogenies, ie, the evolutionary histories of groups of taxa, play a major role in
representing the interrelationships among biological entities. Many software tools for …

▪ Abstract Nonindigenous species can bring about a form of extinction of native flora and
fauna by hybridization and introgression either through purposeful introduction by humans …

" This volume captures the state-of-the-art in the study of insect-plant interactions, and marks
the transformation of the field into evolutionary biology. The contributors present integrative …

The role of natural hybridization in the evolutionary history of numerous species is well
recognized. The impact of introgressive hybridization and hybrid speciation has been …

Speciation is often thought of as a slow process due to the waiting times for mutations that
cause incompatibilities, and permit ecological differentiation or assortative mating. Cases of …
