Speciation with gene flow could be common

Editorial: Could Speciation Across Evolution be Governed by Genetic Switch Codes at Short Tandem Repeats?

How the WTO Could Be Improved

AbstractThis paper examines the impasse in the current Doha Development Round negotiations andasks how the rules of the WTO could be changed to facilitate multilateral negotiations andto increase the welfare of the Member countries. It considers possible changes to the methodof negotiation. As examples of rules which are outdated, it considers the rules relating toregional trade agreements and ...

Speciation with Gene Flow in North American Myotis Bats.

Growing evidence supports the idea that species can diverge in the presence of gene flow. However, most methods of phylogeny estimation do not consider this process, despite the fact that ignoring gene flow is known to bias phylogenetic inference. Furthermore, studies that do consider divergence-with-gene-flow typically do so by estimating rates of gene flow using a isolation-with-migration mod...

Speciation with gene flow and the genetics of habitat transitions.

Whether speciation can advance to completion in the face of initially high levels of gene flow is a very controversial topic in evolutionary biology. Extensive gene exchange is generally considered to homogenize populations and counteract divergence. Moreover, the role of introgressive hybridization in evolution remains largely unexplored in animals, particularly in freshwater zooplankton in wh...

Speciation with gene flow in equids despite extensive chromosomal plasticity.

Horses, asses, and zebras belong to a single genus, Equus, which emerged 4.0-4.5 Mya. Although the equine fossil record represents a textbook example of evolution, the succession of events that gave rise to the diversity of species existing today remains unclear. Here we present six genomes from each living species of asses and zebras. This completes the set of genomes available for all extant ...
