Il peut être difficile d’envisager que la complexité observée dans les génomes aujourd’hui, et la diversité des organismes vivants aient pu être générées uniquement par des modifications aléatoires sur les génomes. Mais il faut garder à l’esprit que ces phénomènes ont eu pour se produire un temps extrêmement long, sur un très grand nombre d’individus. Ces chiffres sont très difficiles à appréhender pour les humains.</lom:string>
