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 …

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 …

A long-debated question concerns the fate of archaic forms of the genus Homo: did they go
extinct without interbreeding with anatomically modern humans, or are their genes present …

In this New York Times bestseller and longlist nominee for the National Book Award,“our
greatest living chronicler of the natural world”(The New York Times), David Quammen …

Ecology affects each of the three principal processes leading to speciation: genetic
differentiation among populations within species, acquisition of reproductive isolation …

Since the time of Charles Darwin, studies of interspecific hybridization have been a major
focus for evolutionary biologists. Although this phenomenon has often been viewed as …

Baboons (genus Papio) are a morphologically and behaviorally diverse clade of catarrhine
monkeys that have experienced hybridization between phenotypically and genetically …

Variation in gene content has been hypothesized to be the primary mode of adaptive
evolution in microorganisms; however, very little is known about the spatial and temporal …

Hybridization, the interbreeding of different species, plays an important role in several
evolutionary processes, such as adaptive trait transfer (Arnold 2006, Arnold et al. 2008 …

Recent research shows that introgression between closely-related species is an important
source of adaptive alleles for a wide range of taxa. Typically, detection of adaptive …
