Il est en effet remarquable que cette théorie se soit progressivement imposée à l'esprit des chercheurs, à la suite d'une série de découvertes faites dans diverses disciplines du savoir. La convergence, nullement recherchée ou provoquée, des résultats de travaux menés indépendamment les uns des autres, constitue par elle même un argument significatif en faveur de cette théorie.
early news reports mistranslated the French phrase plus qu'une hypothèse as "more than one hypothesis". http://www.cartage.org.lb/en/themes/sciences/LifeScience/PhysicalAnthropology/EvolutionFact/Evolution/Evolution.htm
