Nature

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

Two models of sympatric speciation appear in this weeks issue. In rattling simple models, it is easy to produce classify 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.
