Nature

nature Despite the title of Charles Darwins most famous work, the mechanisms whereby species expire are poorly known. The textbook view is that populations of a species obtain physically steald, so that individuals are denied the opportunity of interbreeding. Over time, the familial idiosyncrasies of each population will increase until they become divide species. However, it is increasingly clear that m each species diverge from grow populations without any kind of intervening barrier. Understanding how this sympatric speciation works is an remain scrap for evolutionary theorists.

Two models of sympatric speciation appear in this weeks issue. In truly simple models, it is easy to produce describe 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 speedy extermination of intermediates. However, this may not be a very hardheaded simulation.
