Alleles that introgress between species can influence the evolutionary and ecological fate of
species exposed to novel environments. Hybrid offspring of different species are often unfit …

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 …

Speciation, the evolution of reproductive isolation among populations, is continuous,
complex, and involves multiple, interacting barriers. Until it is complete, the effects of this …

Hybridisation and introgression can dramatically alter the relationships among groups of
species, leading to phylogenetic discordance across the genome and between populations …

PhyloNet was released in 2008 as a software package for representing and analyzing
phylogenetic networks. At the time of its release, the main functionalities in PhyloNet …

Introgression is emerging as an important source of novel genetic variation, alongside
standing variation and mutation. It is adaptive when such introgressed alleles are …

Phylogenomics has revealed the remarkable frequency with which introgression occurs
across the tree of life. These discoveries have been enabled by the rapid growth of methods …

Hybridization has played an important role in the evolution of many lineages. With the
growing availability of genomic tools and advancements in genomic analyses, it is becoming …

Owing to their taxonomic, phenotypic, ecological and behavioural diversity and propensity
for explosive diversification, the assemblages of cichlid fish in the East African Great Lakes …

The species problem has triggered the publication of an almost infinite number of theoretical
and practical studies, including quite a number of books. I should, therefore, perhaps briefly …
