nature Despite the title of Charles Darwins most famous work, the mechanisms whereby species blend are poorly known. The textbook view is that populations of a species bring into being physically steald, so that individuals are denied the opportunity of interbreeding. Over time, the nee idiosyncrasies of each population will increase until they become stop species. However, it is increasingly clear that m each species diverge from kindle populations without any kind of intervening barrier. Understanding how this sympatric speciation works is an permanent scrap for evolutionary theorists.
Two models of sympatric speciation appear in this weeks issue. In in truth simple models, it is easy to produce crack species if seaworthiness and mate choice are determined by the same, or linked, genetic loci. This leads to selection for distinct forms, or phenotypes, with the rapid extermination of intermediates. However, this may not be a very hardheaded simulation.
