Evolution: Speciation in the presence of gene flow
E-Mail Spatial isolation is known to promote speciation - but researchers at Ludwig-Maximilians-Universitaet (LMU) in Munich have now shown that, at least in yeast, the opposite is also true. New ecological variants can also evolve within thoroughly mixed populations. The idea that speciation is based on the selection of variants that are better adapted to the local environmental conditions is at the heart of Charles Darwins theory of the origin of species - and it is now known to be a cent...
