A mon humble avis d'=E9tudiant, il n'y a pas de meilleur m=E9thode.
N'essayez pas de savoir qu'elle est LA meilleure m=E9thode pour la
reconstruction phylog=E9n=E9tique. Les diff=E9rentes approches permettent=
tester les arbres obtenus les uns avec les autres.
La CONGRUENCE permet de juger de la meilleure phylog=E9nie concensuelle...
