Allopatric speciation results from geographic isolation between populations. In the absence of gene flow, reproductive isolation arises gradually and incidentally as a result of mutation, genetic drift and the indirect effects of natural selection driving local adaptation. 2, record 2, English, - allopatric%20speciation

Spéciation qui se produit lorsque deux populations d'une même espèce sont séparées par une barrière biogéographique qui fait qu'elles ne peuvent plus échanger leurs gènes. 2, record 2, French, - sp%C3%A9ciation%20allopatrique

Dans la spéciation allopatrique, des populations initialement interfécondes perdent cette interfécondité (deviennent de nouvelles espèces) [à la suite d'un] isolement géographique. Il s'agit du mode de spéciation le plus fréquent chez les animaux. La spéciation allopatrique peut se produire lorsqu'une barrière géographique (rivière, montagne, vallée, océan, etcetera), coupe l'aire de répartition d'une espèce en différentes zones. Les populations évoluent indépendamment des autres dans chaque zone pouvant donner naissance à une nouvelle espèce. 3, record 2, French, - sp%C3%A9ciation%20allopatrique
