Hybridization may drive rare taxa to extinction through genetic swamping, where the rare
form is replaced by hybrids, or by demographic swamping, where population growth rates …

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

Ancient DNA is transforming our ability to reconstruct historical patterns and mechanisms
shaping modern diversity and distributions. In particular, molecular data from extinct …

" One of the most spectacular facets of the newer studies of evolution has been the
demonstration that evolution has not proceeded by slow, even steps but that seen in the …

Interspecific hybridization can lead to adaptation and speciation, especially in the context of
recent radiations. The emblematic Crocodylus (true crocodiles) is the most broadly …

Hybrid zones represent natural laboratories to study gene flow, divergence and the nature of
species boundaries between closely related taxa. We evaluated the level and extent of …

In Fennoscandia, mountain hare (Lepus timidus) and brown hare (Lepus europaeus)
hybridize and produce fertile offspring, resulting in gene flow across the species barrier …

The Siamese crocodile (Crocodylus siamensis) and Saltwater crocodile (C. porosus) are two
of the most endangered animals in Thailand. Their numbers have been reduced severely by …

Recent empirical studies have demonstrated that speciation with gene flow is more common
than previously thought. From a conservation perspective, the potential negative effects of …

The evolutionary consequences of natural introgression provide a rare opportunity to
retrospectively evaluate how the introduction of exotics or genetic rescue efforts may impact …
