The study of genetic exchange resulting from natural hybridization, horizontal gene transfer,
and viral recombination has long been marked by controversy between researchers holding …

Genetic exchange between divergent evolutionary lineages, from introgressive hybridization
between locally adapted populations to insertion of retroviral sequences into eukaryotic …

Crossing over is well known to have profound effects on patterns of genetic diversity and
genome evolution. Far less direct attention has been paid to another distinct outcome of …

Coupling has emerged as a concept to describe the transition from differentiated
populations to newly evolved species through the strengthening of reproductive isolation …

Introgressed DNA is often deleterious at many loci in the recipient species' genome, and is
therefore purged by selection. Here, we use mathematical modeling and whole-genome …

Chromosomal inversions disrupt recombination in heterozygotes by both reducing crossing-
over within inverted regions and increasing it elsewhere in the genome. The reduction of …

Accumulating prokaryotic gene and genome sequences reveal that the exchange of genetic
information through both homology-dependent recombination and horizontal (lateral) gene …

Since Darwin first proposed that new species could arise without geographic separation,
biologists have debated whether or not divergence occurs in the presence of gene …

Data supporting the occurrence of adaptive trait transfer (ie the transfer of genes and thus
the phenotype of an adaptive trait through viral recombination, lateral gene transfer or …

A recipe for dissolving incipient species into a continuum of phenotypes is to recombine their
genetic material. Therefore, students of speciation have become increasingly interested in …
